The TESLA Technical Design Report Part III: Physics at an e+e- Linear Collider
The four LEP collaborations, ALEPH, DELPHI, L3 and OPAL, have searched for pair-produced charged Higgs bosons in the framework of Two Doublet Models (2HDMs). data experiments been statistically combined. results are interpreted within 2HDM Type I II benchmark scenarios. No significant excess has observed when compared to Standard Model background prediction, combined exclude large regions model parameter space. Charged with mass below 80 \({\rm GeV}/c^{2}\) (Type scenario) or 72.5 scenario,...
This report contains the results of Workshop on CKM Unitarity Triangle, held at CERN 13-16 February 2002 to study determination matrix from available data K, D, and B physics. is a coherent document with chapters covering elements tree level decays K meson mixing global fits unitarity triangle parameters. The impact future measurements also discussed.
During massive data reprocessing operations an ATLAS Conditions Database application must support concurrent access from numerous processing jobs running on the Grid. By simulating realistic work-flow, database scalability tests provided feedback for Db software optimization and allowed precise determination of required distributed resources. In one take into account chaotic nature Grid computing characterized by peak loads, which can be much higher than average rates. To validate...
B physics results from e+e- annihilation at the Z0 resonance are reviewed. A vast programme is summarized, including study of B+, B0d, B0s and b baryon lifetimes, time dependence Bd0-Bd0 Bs0-Bs0 oscillations, width difference in system, measurements magnitudes CKM matrix elements {Vcb} {Vub}.
A new scalar resonance, called the radion, with couplings to fermions and bosons similar those of Higgs boson, is predicted in framework Randall–Sundrum models, proposed solutions hierarchy problem one extra dimension. An important distinction between radion boson that would couple directly gluon pairs, particular its decay products include a significant fraction jets. The has same quantum numbers as Standard Model (SM) therefore they can mix, resulting mass eigenstates having properties...
It has been suggested to realize a factory for 10^9 Z^0 through linear e^+e^- collider with polarized beams. Very likely the relevant CP studies B mesons will already have performed at factories by that time, hence GIGA-Z be third generation b physics experiment. Yet such facility would provide us unique opportunities in domain of beauty essential significance even 2010: (1) Production and decay baryons; (2) searching probing transitions driven --> q ν\barν; (3) detailed comprehensive...
Measurements of top quark properties performed at the Large Hadron Collider are reviewed, with a particular emphasis on top-pair charge asymmetries, spin correlations and polarization measurements by ATLAS CMS collaborations. The generally in good agreement predictions from next-to-leading-order QCD calculations, no deviations Standard Model expectations have been seen.
Separate collider experiments observe the top quark without its usual antiparticle partner in unique processes that could give insight into new physics, such as additional sets of quarks.
Top quark physics measurements performed using data from the ATLAS detector at LHC rely on efficient reconstruction and precise calibration of leptons, jets missing transverse energy. A review techniques used to reconstruct such objects is given, with an emphasis uncertainties achieved for energy efficiency measurements, illustrated their impact key top results.
