Meson Physics
Different ways to express the vector meson dominance (VMD) assumption are examined by analysing a wide set of data. These data cover e + e − → π + π − and e + e − → µ + µ − cross sections, the I = l = 1 ππ phase shift and the near threshold predictions of chiral perturbation theory (ChPT). We find that, of the models 1 Permanent address. 2 Present address. considered here, only that proposed by...
متن کاملSummary of Experimental Meson Physics
Meson physics is a very broad field, and this workshop covers a very large part of it, with about 25 plenary and 50 parallel talks. I can not possible attempt to summarize all that. So, I will pick and choose from what was presented, a process which is admittedly very subjective, and add some new and interesting results which were not talked about. I will also update some results which have app...
متن کاملNew Results in Vector Meson Dominance and Rho Meson Physics
Recent results by Benayoun et al. comparing the predictions of a range of existing models based on the Vector Meson Dominance hypothesis are summarized and discussed. These are compared with data on ee → ππ and ee → μμ cross-sections and the phase and near-threshold behavior of the timelike pion form factor, with the aim of determining which (if any) of these models is capable of providing an a...
متن کاملNew Physics Effects from B Meson Decays
In this talk, we point out some of the present and future possible signatures of physics beyond the Standard Model from B-meson decays, taking R-parity conserving and violating supersymmetry as illustrative examples.
متن کاملNon-perturbative QCD Modeling and Meson Physics
Using a ladder-rainbow kernel previously established for light quark hadron physics, we explore the extension to masses and electroweak decay constants of ground state pseudoscalar and vector quarkonia and heavy-light mesons in the cand b-quark regions. We make a systematic study of the effectiveness of a constituent mass concept as a replacement for a heavy quark dressed propagator for such st...
