Hard-photon production at s = 161 and 172 GeV at LEP
Abstract
We have studied the process e+e− → nγ (n ≥ 2) at centre-of-mass energies of 161.3 GeV and 172.1 GeV. The analysis is based on a sample of events collected by the L3 detector in 1996 corresponding to total integrated luminosities of 10.7 pb−1 and 10.1 pb−1 respectively. The observed rates of events with two and more photons and the characteristic distributions are in good agreement with the Standard Model expectations. This is used to set lower …
