e+e- PHYSICS NEAR CHARM THRESHOLD VIA THE CRYSTAL BALL
نویسنده
چکیده
We discuss the use of the Crystal Ball detector for the study of e+eannihilations near charm threshold: at the $(3097), $'(3685), $"(3770) and in the "continuum" 37701&<4500 MeV. This paper will concentrate on the special techniques available to the Crystal Ball which allow measurement of inclusive y, noand n cross sections. Preliminary results for these processes at particular center of mass energies are presented. An update of the inclusive and exclusive evidence for the nc(2980), for the sake of completeness, is given in the Appendix.

→ τ + τ − at the threshold and beyond
The excitation curve for the τ τ− production in electron positron annihilation near the threshold is revisited with the aim of updating and extending a previous work. We find that the corrections of the relative magnitude O(α) near the threshold are significantly contributed by the radiative modification of the Coulomb interaction between the τ leptons. The interpolation between the Coulomb eff...
متن کاملSLAC-PUB-4996 June 1989 (T/E) PHYSICS OF A HIGH LUMINOSITY COLLIDER OPERATED NEAR CHARM AND TAU PAIR THRESHOLDS
The current plans for a high luminosity e+ecollider operated between 3.0 and 4.4 GeV/c2 are described. Such a dedicated facility (The Tau-Charm Factory), operating near tau-pair and charm thresholds would allow studies of the decay of the third generation tau-lepton and the second generation c-quark with unprecedented precision and control of systematics. The charm physics of such a facility is...
متن کاملCharm and Bottom Quark Production Cross Sections Near Threshold
The cross sections for charm and bottom quark production in the threshold region are discussed. We consider the effects of an all order resummation of initial state soft-plus-virtual gluon radiation on the total cross sections compared to the order αs results. This work was supported in part by the Director, Office of Energy Research, Division of Nuclear Physics of the Office of High Energy and...
متن کاملTau Physics Prospects at the Tau-charm Factory and at Other Machines
The prospects for tau physics at future high-luminosity facilities are briefly discussed. Although important (and often complementary) contributions will be made from other machines, the unique experimental environment near threshold makes the Tau-Charm Factory the best experimental tool for τ physics. Talk given at the Marbella Workshop on the Tau-Charm Factory Marbella, Spain, June 1993 ∗ On ...
متن کاملThreshold Effects on Heavy Quark Production in γγ Interactions
The exchange of gluons between heavy quarks produced in e + e − interactions results in an enhancement of their production near threshold. We study QCD threshold effects in γγ collisions. The results are relevant to heavy quark production by beam-strahlung and laser back-scattering in future linear collider experiments. Detailed predictions for top, bottom and charm production are presented.
