Abstract:

We report on high statistics Bhabha scattering data taken with the TASSO experiment at PETRA at center of mass energies from 12 GeV to 46.8 GeV. We present an analysis in terms of electroweak parameters of the standard model, give limits on QED cut-off parameters and look for possible signs of compositeness. © 1988 Springer-Verlag.

Abstract:

The process γγ→π⁺π^-π⁺π^- has been investigated in reactions of the type e⁺e^-→e⁺e^-π⁺π^-π⁺π^- in the single tag mode. The range of the four momentum squared of one of the virtual photons was 0.28 GeV²/c²≦Q²≦3.6 GeV²/c², the average being 〈Q²〉=0.92 GeV²/c²; the other photon was quasi real. The reaction is mainly described by the channels γγ→��⁰��⁰ and γγ→4π (phase space), occuring with about equal probability. The Q²-dependence of the cross section is in agreement with the �� form factor. © 1988 Springer-Verlag.
