tau lepton decays: hadronic currents from data of Belle and BaBar and new physics signatures at LHC .
Institute of Nuclear Physics PAN, Cracow Poland, Radzikowskiego 152
15-22 September 2013
Purpose of the meeting
Tau leptons, elementary constituents of matter are of fundamental importance for science. Better modelling of their decays in modern language of hadronic interactions at intermediate energies may lead to a breakthrough in understanding relation between quantum chromodynamics and effective models of hadrons interactions. This is important not only for description of hadrons interactions themselves, but also for strophysics. Evolution of stars and modelling of early Universe depends on strong interactions. Tau leptons are used for establishing signatures of New Physics at LHC measurements, better understanding of their decays may lead to better separation between signals of new physics and backgrounds.
The purpose of the meeting is to discuss work on and embed, for tau lepton decays, the theoretical predictions calculated from models like Resonance Chiral Theory, into phenomenologically useful tools. Better algorithms for confronting theoretical predictions with experimental data have to be also prepared. Then, final adaptation of theoretical predictions (fits to the data of the effective couplings and masses) has to be performed. If after the fits discrepancies remain, the model under investigation can be excluded but guidance for the further development is obtained.
Discussing tools and progressing in work within such a programme is the main purpose of the meeting. Thanks to the results of this project physics gains of high energy experiments will be improved as well, in particular of LHC experiments. Better description of the data, in form of hadronic currents consistent with theoretical models, may give new starting point for studies of QCD at low and intermediate energies. In these regimes perturbative methods are so far of limited use and need refinement. Such outcome would be of the great importance and can provide a breakthrough.
Related topics are expected to be discussed during the meeting as well and the complete frame of this workshop will be organized to stimulate present work on research concentrated around TAUOLA (in particulat TauSpinner) PHOTOS Monte Carlo programs as well as their practical use and systematic uncertainties.
