Determination of ±s from a differential-jet-multiplicity distribution in e+e- collisions at ss =29 and 91 GeV

We measured the differential jet-multiplicity distribution in {ital e}{sup +}{ital e}{sup {minus}} annihilation with the Mark II detector. This distribution is compared with the second-order QCD prediction and {alpha}{sub {ital s}} is determined to be 0.123{plus minus}0.009{plus minus}0.005 at {radical}{ital s}{approx}{ital M}{sub {ital Z}} (at the SLAC Linear Collider) and 0.149{plus minus}0.002{plus minus}0.007 at {radical}{ital s}=29 GeV (at the SLAC storage ring PEP). The running of {alpha}{sub {ital s}} between these two center-of-mass energies is consistent with the QCD prediction.

Colliding a Linear Electron Beam With a Storage Ring Beam

P. Grosse-Wiesmann

Abstract We investigate the possibility of colliding a linear accelerator electron beam with a particle beam stored in a circular storage ring. Such a scheme allows e + e − colliders with a center-of-mass energy of a few hundred GeV and eP colliders with a center-of-mass energy of several TeV. High luminosities are possible for both colliders.

CP violation at the Zo with polarized beams

W.B. Atwood; Isard Dunietz; P. Grosse-Wiesmann

Abstract The forward-backward asymmetry in e + e − annihilation induced by neutral currents allows an effective particle-antiparticle separation. This is used to define a simple CP violating observable. At the Z o resonance, where th production rates are high, polarized electrons may increase the forward-backward asymmetries by up to a factor six. The number of events necessary to establish a CP -violating effect with neutral B mesons is reduced by about an order of magnitude compared with the usual lepton tag method.
