Implications of ∆ ρ and CHARM II data for Z ′ Physics
نویسنده
چکیده
We discuss the constraints on the Z ′ model parameters coming from Zpole and low-energy νμ − e scattering data in the frame work of GUTmotivated models. We find that when the coupling constant of the extra U(1) is small (large) the parameter space is mainly determined by the Z-pole (the low-energy νμ − e scattering) data. e-mail:[email protected] Address after 1st of October: ICTP, Trieste, Italy

Rare Charm Decays
I dedicate this paper (as I did my talk) to Jean Tran Thanh Van and his wife for their valuable contributions over many years to our discipline. My talk summarized a recent paper 1 written in collaboration with Gustavo Burdman, JoAnne Hewett and Sandip Pakvasa on the topic of rare flavor-changing neutral current (FCNC) decays of D mesons. Transitions of this class include: (i) D → V γ (V = ρ, ω...
متن کاملCharm Physics with Bes-iii at Bepc-ii
We report on the charm physics potential at BES-III at BEPC-II which will make significant contribution to quark flavor physics this decade. The charm physics program will include studies of leptonic, semileptonic and hadronic charm decays, and tests for physics beyond the Standard Model. Event samples of the order of 30 million DD pairs, 2 million D S D− S pairs at threshold and 10 × 10 J/ψ de...
متن کاملNew Charm(onium) Results from Cdf
After many upgrades to the CDF detector and to the accelerator complex, Run II began in April 2001. The new detector has improved capabilities for charm physics, and first results from the analysis of early Tevatron Run II data are reported here.
متن کاملTau Charm Factory Physics
Physics from a Tau Charm Factory is presented. . T au Charm Factories proposed for future machines will provide powerful and unique facilities to study a variety of physics topics: the tau lepton, charm mesons, charmonium and the J/vdecays. These topics cover the physics of the members of the first and second quark doublets and the third lepton doublet. The number of Table. 1 Tau Charm Factory ...
متن کاملRecent Progress in PYTHIA
PYTHIA is a general-purpose event generator for multiparticle production in high-energy physics. After a general introduction and program news survey, some areas of recent physics progress are considered: the matching to matrix elements, especially for W/Z production; charm and bottom hadronization; multiple interactions; and interconnection effects. The report concludes with some words on the ...
