This thesis presents the first search for a neutral Minimal Supersymmetric Standard
Model Higgs boson decaying to a pair of hadronic taus in proton-proton collisions with
a center-of-mass energy of √s = 7 TeV. Results are presented for an integrated lumi-
nosity of 1.056 fb−1 using data from the ATLAS detector at the Large Hadron Collider.
After signal selection, 245 events are observed. The number of events is consistent the
background estimate of 256 ± 26. An exclusion limit for the Higgs boson production is
derived as a function of (cross-section)×(branching ratio). This limit is presented as a
function of two parameters: mA and tanβ in the mmax scenario. A point in the (mA, h
tanβ) phase space is excluded if the signal hypothesis is rejected at the 95% confidence level.
