Full textThe phenomenology of the pseudo scalar mesons Ds and Bs and of the vector mesons Ds* and Bs*, each of which contain a heavy and a light quark, was investigated in simulations of quenched lattice QCD. The work was particularly focused on the minimisation of all systematic errors within this approximation. The decay constants FDs and FDs* and the difference in the masses between the pseudo scalar Ds-meson and the corresponding vector meson Ds* were determined from the direct computer simulation of lattice QCD in large physical volume (L~1.5fm). As an aside, the renormalisation group invariant charm quark mass M_c could be obtained from the simulation results. A platform independent software was developed for the Monte-Carlo simulations of lattice QCD within the Schrödinger Functional. A number of simulations at different lattice constants allowed the extrapolation of the results to the continuum. Since comparable simulations for the Bs- and the Bs*-meson are not feasible due to the large mass of the b-meson, an interpolation in the meson mass to its physical point was carried out for the decay constant and the mass splitting. The interpolation was carried out between the static limit and the range of meson masses of order m_Ds. The desired observables were therefore determined and extrapolated to the continuum for altogether six meson masses. The functional form of the subsequent interpolation in the meson mass to the static limit was guided by the prediction of the Heavy Quark Effective Theory (HQET). In order to apply it to the results obtained in QCD, a set of conversion functions between HQET and QCD were derived and evaluated numerically with input from results in perturbation theory. The final results are FDs = 226(7)MeV, FDs* = 239(18)MeV, FBs = 198(9)MeV, m_{Ds*}-m_{Ds} = 136(9)MeV, m_{Bs*}-m_{Bs} = 63(6)MeV and M_c = 1.60(3)GeV. The result for the renormalisation group invariant charm quark mass is equivalent to mbar_c^MSbar(mbar_c) = 1.27(3)GeV. The analysis of the interpolation furthermore allowed to estimate, that the lowest order corrections to the static limit in HQET are relatively small. One therefore can expect HQET to offer a good approximation in the range of B-physics.

Full textIn this thesis a search is presented for heavy neutral pseudoscalar A and scalar H Higgs bosons, produced in gg fusion and decaying into a top-antitop quark pair. The search is conducted on the full proton-proton collisions dataset recorded by the ATLAS detector at the Large Hadron Collider at a centre-of-mass collision energy of 8 TeV and corresponding to an integrated luminosity of 20.3 fb−1. The signal process and the main background from top quark pair production via the gg fusion strong process, interfere heavily, distorting the signal shape from the pure Breit-Wigner resonance peak to a peak-dip structure. This analysis is the first one at the LHC that fully takes into account the interference between a signal and the background processes. The search relies on the statistical analysis of the top quark pair invariant mass spectrum, which is reconstructed in signal candidate events with a high-transverse momentum electron or muon, large missing transverse energy from the undetected neutrino and at least four jets. No significant deviation from the expected SM background is observed in data. Exclusion limits are derived in the context of the type-II Two-Higgs-Doublet Model, for Higgs boson masses of 500 and 750 GeV and in the low tan(\beta) parameter region, where tan(\beta) is the ratio of the vacuum expectation values of the two Higgs doublet fields. These parameter regions have been largely unexplored by searches in any final state.
