Time Reversal Violation in Nuclear Effective Field Theory

Hockings, William Hill January 2006 (has links)
The lack of invariance with respect to time reversal (T) of the weak interactions has long been known. However, T violation has yet to be observed from flavor-diagonal sources, where the primary quantities of interest are electric dipole moments (EDMs). Weak T violation gives EDMs that are far too small, but strong T violation via flavor-diagonal sources could give EDMs strong enough to be detected in the near future. It is thus important to understand precisely how various quark-level sources of T violation manifest themselves in hadronic physics.A useful technique for dealing with low-energy phenomena involving nucleons, nuclei, and various mesons, is effective field theory (EFT). The formalism and methodology of EFT are presented, followed by an introduction to the construction of chiral Lagrangians.A motivation for the study of T violation beyond the weak interactions is then given, with brief introductions to the most important sources of T violation.The QCD theta term is looked at using two differentapproaches. First, enforcing vacuum stability at quark level, a series of T-violating interactions ensue. Second, enforcing vacuum stability at hadronic level via field redefinitions, spurious interactions are demonstrated to be avoidable. Both approaches involve a constraining relationship between theta-term T violation and up-down quark-mass-difference isospin violation. The quark chromo-EDMs are shown to be identical to the theta term in their chiral symmetry properties. The quark EDMs and Weinberg operator,conversely, are shown to generate new interactions in addition to those generated by the theta term, differing nucleon EDM contributions in particular.The electric dipole form factor (EDFF) of the nucleon, with a theta term source, is calculated in both leading and subleading orders in chiral perturbation theory, with the momentum dependence at both orders given entirely by contributions from the pion cloud. Theleading result is purely isovector, while an isoscalar result appears in subleading order. The isoscalar EDM is used as a lower-bound estimate of the deuteron EDM. The momentum dependence of the EDFF for small momentum transfer is related to the electromagnetic nucleonSchiff moment, which is computed to subleading order.

Angular analysis and search for CP violation in the decay B0 → J/ΨK*0

Sparkes, Ailsa January 2013 (has links)
LHCb is a precision heavy-flavour experiment at the Large Hadron Collider and in 2011 collected just over 1 fb-1 of data at a centre-of-mass energy of √s = 7 TeV. The Ring Imaging Cherenkov (RICH) detectors allow LHCb to identify charged hadrons by measuring their velocity. The system uses Hybrid Photon Detectors to detect rings of single photons emitted by particles travelling through the RICH radiators. The performance-monitoring of these photon detectors whilst data-taking is presented and discussed. LHCb aims to perform precise measurements of Charge-Parity violation in B and D mesons. The final state of B0 → J/Ψ(→μ=μ-)K*(→K=π-) is an admixture of parity-odd and parity-even final states, which are either longitudinally or transversely polarized. These contributions can be separated by performing an angular analysis. The polarization amplitudes and phases of the final state are measured. No difference is observed between the B0 and B0 flavour eigenstates which indicates that Charge-Parity symmetry has been conserved. The ambiguity in the measurement of the strong phase has been resolved by studying the P-wave and S-wave interference in the K/π mass system. The deviation from zero or π in the measurement of the strong phases indicates that final state interactions have occurred. In addition, the prediction that the polarization amplitudes should be similar to those of B0s→ J/Ψo is confirmed.

La condamnation symbolique / The symbolic condemnation

Brunie, Juliette 05 April 2017 (has links)
Malgré une référence expresse faite à la condamnation symbolique par le législateur, cette notion demeure méconnue en droit français. Pouvant être définie comme une décision rendue par une autorité ayant pouvoir de juridiction prononçant, à l'égard d'un individu ou d'un acte, une sanction morale dépourvue d'incidences matérielles réelles exprimant la reconnaissance de la violation d'un droit ou du Droit imputable à cet individu ou à cet acte, la condamnation symbolique est présente de manière diffuse dans le droit français : droit civil, droit administratif et droit pénal. Si les dommages et intérêts symboliques en sont l'illustration la plus évidente, ils n'en sont pas la seule. Annulations dans l'intérêt de la loi, exemptions légale et judiciaire de peine, admonestation … sont aussi des condamnations symboliques. L'étude de l'ensemble de ces illustrations a permis de constater que toutes les condamnations symboliques ne sont pas guidées par la même logique. Quand certaines peuvent être qualifiées de normatives, d'autres sont recognitives ou mitigatives. / Despite a reference do to the symbolic condemnation by the lawmaker, this notion remains unknown in French law. It can be defined as a decision taken by an authority having jurisidiction power pronouncing, towards a person or an act, a moral sanction without material impact expressing the recognition of a right or rule of law's violation accountable to this person or act, the symbolic condemnation is present diffusely in French law : civil law, administrative law and criminal law. If nominal damages are the more obvious illustration, it's not the only. Cancellations in interest of law, absolute discharge, reprimand… are also symbolic condemnation. The study of all of these illustrations has enabled to notice that all the symbolics condemnation are not guided by the same logical. When some can be qualified as normatives, others are recognitives or mitigatives.

Sexual and Nonsexual Boundary Violations Between Sport Psychology Professionals and Their Client-athletes

Moles, Troy 05 1900 (has links)
Sexual attraction (SA), as well as sexual (SBVs) and nonsexual boundary violations (NSBVs), have been identified as matters of ethical concern, being viewed as harmful within mental health or counseling relationships. Much of the literature in the area of SA and SBVs has focused on the counselor-client relationship, but it has been investigated only minimally in the field of sport psychology and specifically with regard to sport psychology professionals (SPPs). Because SA, SBVs, and NSBVs between SPPs and their client-athletes seem to be potentially problematic concerns in need of empirical investigation and practical scrutiny, the aim of this study was to examine: (a) the incidence of SBV and NSBV beliefs and behaviors among SPPs; (b) SPPs' feelings regarding SA for and from client-athletes; and (c) SPPs' willingness to seek supervision to manage their SA beliefs and behaviors towards client-athletes. SPPs (n = 365) completed the Survey of Applied Sport Psychologists (SASP) via e-mail or regular mail. As expected, SPPs experienced SA (40.6%) and generally did not experience strong feelings as a result of the SA. However, of the SPPs experiencing SA, 13.5% of males and 13.8% of females engaged in a SBV with a client-athlete. NSBV behaviors and beliefs are also reported. Chi-squared analyses revealed male SPPs engaged in nonsexual touching with their client-athletes more frequently than female SPPs. T-tests suggested ethically trained SPPs were more likely to seek supervision as a result of SA and view certain NSBVs as good professional behavior in comparison to non-ethically trained SPPs. Appropriate supervision and ethical training for SPPs experiencing SA could be helpful in the management of potential future SBV or NSBV behaviors. Implications for SPPs working with athletes, limitations of the present study, and recommendations for future research are discussed.

The Effects of Body Violation on the Lived Experiences of Young Women

Mirian, Raha 19 July 2012 (has links)
The experience of one’s self as ‘living in and through the body’ has been coined embodiment. The interactions between felt inner states and interactions with one’s environment mutually construct the level and quality of this experience. Embodiment relies on a sense of safety and ownership over one’s body territory. Existing research cites the emotional, psychological,physical, and interpersonal effects of violence against women, yet the underlying disruption to body ownership that follows such violation has largely remained unidentified. Using the framework offered by the groundbreaking Developmental Theory of Embodiment, this study examines the effects of a broader spectrum of violation to body ownership than what has been examined to date. Three interviews of each of seven women, over a period of two years, provide insights into experiences of living in and with the female body as this relates to various forms of trauma.
