“…Above the Z peak, the e + e − → Zγ process provides a very clean photon-tagged sample of on-shell Z bosons, with which the Z properties can be measured. From the WW threshold scan alone, the cross section of about 5 pb [59][60][61][62] ensures that 10 million Zγ events will be produced in each TLEP experiment with a Z → νν decay and a high-energy photon in the detector acceptance. The three million Zγ events with leptonic Z decays will in turn provide a direct measurement of the ratio Γ inv Z /Γ lept Z , in which uncertainties associated with absolute luminosity and photon detection efficiency cancel.…”

“…out to examine the neutrino counting reaction e + e − → γνν in the SM and also to look for new particles that are long-lived or stable [65][66][67][68][69][70][71][72][73][74][75][76]. Thus the acquired data may be useful for restricting the process e + e − → γS k S * l if S k,l are long-lived or, for k, l = 3, if they decay (sequentially) into S 3 plus light neutrinos.…”

“…energies within the range 130-207 GeV, and the observed cross-sections vary also with cuts on the photon energy E γ and angle θ γ relative to the beam direction. From a collection of these data [65][66][67][68][69][70][71][72][73][74][75][76] tabulated in ref. [77], one can see that the majority of the measured and SM values of the cross section agree with each other at the one-sigma level.…”
