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.

Electron-positron annihilation at high energies

The experimental physics programme of PEP and PETRA is presented. The data from 11 independent experiments are collated according to subject matter and compared with theory. The author starts with a

A measurement of electroweak effects in the reactione+e− → τ+τ− at 35.0 and 42.4 GeV

We report on total cross section and forward backward charge asymmetry measurements of the reactione+e− → τ+τ− at centre of mass energies of 35.0 GeV and 42.4 GeV using the TASSO detector. Including

First observation of the Top Quark at the Large Hadron Collider

This thesis presents the measurement of the top quark pair production cross section in the CMS detector at the CERN Large Hadron Collider (LHC). At LHC, the top quark is produced predominantly

Model-Independent Bounds on Kinetic Mixing

New Abelian vector bosons can kinetically mix with the hypercharge gauge boson of the Standard Model. This letter computes the model independent limits on vector bosons with masses from 1 GeV to 1



An improved measurement of electroweak couplings frome+e−→e+e− ande+e−→μ+μ−

We present an analysis of electroweak leptonic couplings from high statistics experiments on Bhabha scattering and μ pair production at an energy of 34.5 GeV. The forward-backward charge asymmetry of

New Tests for Quark and Lepton Substructure

If quarks and leptons are composite at the energy scale ..lambda.., the strong forces binding their constituents induce flavor-diagonal contact interactions, which have significant effects at

The production and decay of Tau leptons ine+e− annihilation at PETRA energies

We have observed τ pair production at average CM energies of 13.9, 22.3, 34.5 and 43.1 GeV. The cross-sections are consistent with QED, the cut off parameters beingΛ+>161 GeV andΛ−169 GeV (95% CL).
