Study of muon-pair production at centre-of-mass energies from 20 to 136 GeV with the ALEPH detector
The total cross section and the forward-backward asymmetry for the process e+e− → μ+μ−(nγ) are measured in the energy range 20–136 GeV by reconstructing the effective centre-of-mass energy after initial state radiation. The analysis is based on the data recorded with the ALEPH detector at LEP betwee...
