The non-linear Hartree-Fock (HF) equations are usually solved via the iterative self-consistent field method. However, there is no a priori guarantee of convergence, especially in systems with strong electron correlation where symmetry breaking occurs. This work focuses on closed- shell systems in the HF approximation and the (in)stability of the found solutions, and proposes new deterministic methods for the localization of both symmetry-adapted and broken symmetry solutions. We employ a perturbative method and show how one can always obtain a symmetry-adapted solution of the HF equations. We also determine the radius of convergence, related to the existence of at least one bound state, of the perturbative series. Next, we rederive the matrix of stability and adapt it to spin and orbital symmetry. Calculation of higher energy variations follows, first in terms of spin-orbitals and then orbitals. Motivated by the investigation of the structure of a broken-symmetry solution, we propose a new deterministic method for the localization of a broken-symmetry solution. The general expressions are verified by reformulating the stability conditions for simple cases. The proposed methods are successfully applied to helium-, beryllium- and neon-like systems.

Title: Dynamical symmetry breaking in models with strong Yukawa in- teractions Author: Petr Beneš Department: Institute of Theoretical Physics, Faculty of Mathematics and Physics, Charles University Supervisor: Ing. Jiří Hošek, DrSc., Department of Theoretical Physics, Nu- clear Physics Institute, Academy of Sciences of the Czech Repub- lic Abstract: The primary aim of the thesis is to explore the possibility of spon- taneous symmetry breaking by strong Yukawa dynamics. Tech- nically, the symmetry is assumed to be broken by formation of symmetry-breaking parts of both the scalar and the fermion prop- agators, rather than by the scalar vacuum expectation values. The idea is first introduced on an example of a toy model with the underlying symmetry being an Abelian one and later applied to a realistic model of electroweak interaction. In addition, the thesis also deals with some more general, model-independent is- sues, applicable not only to the discussed model of strong Yukawa dynamics, but to a wider class of models with dynamical mass generation. First of these issues is the problem of fermion flavor mixing in the presence of fermion self-energies with a general mo- mentum dependence. It is in particular shown how to define the CKM matrix in such models and argued that it can come out in principle...

In this thesis we introduce the spherical, central, angular, halfspace and regression symmetry of random vectors and their measures. Firstly we deal with their mutual relations and equivalent expressions. We also study the uniqueness of the center of individual symmetries and other interesting properties. Then we define the halfspace, projection, spatial and regression multidimensional median and show their properties. Finally we look at the relationships between these medians and symmetric distributions. 1

Although scoliosis is defined as a deviation of the spine in the frontal plane above 10ř according to Cobb, the spine is deformed in three planes. The chest is also affected at the same time. The most common type is idiopathic scoliosis, which has multifactorial etiopathogenesis. The thesis summarizes available information on kinesiology of the spine, classification of idiopathic scoliosis, its incidence, etiology, diagnostics, treatment and specific physiotherapeutic exercises. The practical part is devoted to assessing the symmetry of the patient's torso from the photographic documentation of the posture by SCODIAC 2.3. Indices evaluating hull asymmetry from the back or front (POTSI, ATSI) result from mathematical calculation. The smaller the number, the more symmetrical the posture. Correlation of POTSI index and Cobb angle is explored. 20 patients (18 girls and 2 boys) with idiopathic scoliosis up to 47ř according to Cobb aged between 7 to 18 years were selected for the study. All patients were subjected to anamnestic data collection, kinesiology analysis and a questionnaire. The results were statistically processed. SCODIAC software is one of the options offered to evaluate torso asymmetry and assess posture changes after therapy. It acts as a feedback for a physiotherapist and motivates...

Theme: Evaluation of stability, sensorimotor and symmetry of football players after ACL reconstruction by MFT S3 tool. Student: Bc. Simon Otto Supervisor: PhDr. Ales Kaplan, PhD. Aims: The aim of the diploma thesis is evaluation of stability, sensorimotor and symmetry of chosen group of football players (n=4) after ACL injury by MFT S3 check test. Methodology: The level of stability, sensorimotor and symmetry was measured by MFT S3 tool and then evaluated with activities during the recondition season. Results: The study proved that some activities are more or less suitable for development of stability and sensorimotor. The biggest positive effect had special workouts aimed for tight muscles and the knee joint. The lowest values were measured after the run and football trainings when the stability and the sensorimotor were impaired. The values were higher in sagittal plane due the preferable sagittal movement used during the football matches. It is important to realize that the recondition process is needs to be lead individually for every athlete after ACL surgery because there is not any universal methodological procedure. Key words: Stability, sensorimotor, symmetry, injury, knee, ACL, football, recondition.

Theme: Evaluation of stability level of athletes (14-15 years) by MFT S3 Check Aims: The aim of this diploma thesis is evaluation of stability level, sensomotor and pose symmetry of both-limb posture by MFT S3 Check system at a selected group of children attending an athletic club. I used the comparison of values between a group of girls and boys. Methodology: The level of stability, sensomotor and pose symmetry was measured in the course of the race season. The data was measured by MFT S3 Check system and further one leg stand test was used. Measurment was supplemented with a questionnaire survey. I used the comparison of values between a group of girls and boys Results: In the test MFT S3 Check the girls achieved above-average evaluation in the index values and stability sensomotorics than boys, who were evaluated in the test below average. The sum of the average values of divergences from the ideal ratio at both monitored levels were lower by 0.15 at boys. There was proved a medium dependence of body weight and BMI values on the level of stability. Shoe size, incidence of ankle injuries, nor the results of the one leg stand test had no impact on the level of stability. Key words: senzomotor, stability, symmetry, 14-15 years, athletics, testing

Diploma thesis deals with the effect of the hairstyle symmetry on the female face attractiveness. The aim of the thesis is to experimentally find out the possible relationship between the hairstyle symmetry and the attractiveness of the female face. To map out the views of attractiveness, an online questionnaire was submitted to the respondents of both sexes to evaluate female faces with a symmetrical and asymmetric hairstyles. A total of 56 images were created, which were evaluated by the respondents in terms of attractiveness on the scale of 1-10. Most respondents slightly favored the symmetrical hairstyles, only one sample of male respondents slightly favored the asymmetric hairstyles. Since the difference in symmetrical and asymmetric variations was not statistically significant in any case, it is possible to claim that the symmetry of the hairstyle does not affect the attractiveness of the female face.

La violation de CP et le problème de la génération des masses, seront les deux<br />questions fondamentales posées à la recherche en Physique des Particules à l'aube du<br />troisième millénaire. L'expérience BaBar, installée auprès de l'usine à B, PEP-II du<br />SLAC, se propose d'étudier la violation de CP dans le système des mésons beaux.<br />Elle permettra de tester la cohérence du Modèle Standard avec la violation de CP<br />mesurée ou de mettre en évidence de nouvelles sources de violation de CP.<br /><br />Pour l'étude des canaux de violation de CP avec BaBar il est fondamental<br />d'identifier les particules produites au cours des désintégrations. La première partie<br />de mon travail de thèse porte sur l'étude que nous avons effectuée sur un projet de<br />compteur Cherenkov à seuil en aérogel dans le but d'identifier les particules chargées<br />et en particulier de séparer les pions des kaons entre 0.5 et 4.3 GeV/c. Cette étude<br />inclut : les recherches préliminaires sur les matériaux employés (réflecteurs, décaleurs<br />de longueur d'onde et aérogels), la géométrie des cellules et des guides de lumière et<br />la simulation des prototypes. Des tests en faisceau ont démontré la faisabilité de ce<br />détecteur.<br /><br />La deuxième partie de mon travail de thèse porte sur l'étude du potentiel<br />d'extraction des paramètres de violation de CP de l'expérience BaBar pour le canal<br />B0 -> J/Psi K0s où le J/Psi, se désintègre en mode leptonique. Sont étudiés : l'efficacité<br />de reconstruction, le niveau du bruit de fond, les performances d'étiquetage du B<br />ainsi que les résolutions sur la position des vertex de désintégration des B. A partir<br />de cela, l'étude de l'asymétrie, par une méthode probabiliste ou d'ajustement, nous<br />permet d'estimer la résolution sur le paramètre sin ,. du triangle d'unitarité. Une<br />incertitude de 0.085 sur sin 2b pourra être atteinte par l'expérience BaBar en 1 an<br />de prise de données, à une luminosité intégrée de 30 fbarn-1.

L'expérience BABAR, située à SLAC, étudie depuis 1999 les désintégrations<br />des mésons B à partir de collisions entre électrons et positrons à une énergie égale<br />à la masse du Upsilon(4S). Le but premier de l'expérience a été de mesurer le paramètre<br />sin(2 beta) de la violation de la symétrie CP dans le modèle standard. Cette mesure<br />demande de connaître avec précision l'échelle de longueur absolue du détecteur.<br />Une méthode a été mise au point pour déterminer cette échelle, en utilisant les<br />interactions nucléaires dans la matière du détecteur et en particulier dans le tube<br />à vide de l'expérience. L'échelle de longueur du détecteur dans la direction des<br />faisceaux a ainsi été estimée avec une précision meilleure que 1 %. L'incertitude<br />liée à la détermination des longueurs par le détecteur dans les mesures des temps<br />de vie des B et de leur fréquence d'oscillation devient alors négligeable par rapport<br />aux autres erreurs systématiques.<br /><br />Le contenu en kaons chargés des désintégrations des mésons B intervient aussi<br />dans la mesure de sin(2 beta) pour étiqueter la saveur du deuxième B dans les événements<br />contenant un B se désintégrant dans un état propre de CP. La charge du<br />kaon est directement liée à la saveur du B. Une des sources de kaons de mauvais<br />signe pouvant fausser l'étiquetage provient de désintégrations de mésons D<br />de mauvais signe (B -> D X).<br />Les modes de désintégration doublement charmés<br />B -> DDbar K sont un des modes donnant des D de mauvais signe. Les vingt-deux<br />modes de désintégration sont reconstruits de façon exclusive et leurs taux<br />de branchement calculés avec une précision suffisante pour établir que les désintégrations B -> DDbar K ne sont pas les seules sources de D de mauvais signe dans les désintégrations des mésons B.
