Photon atomic mass

WebReal photons are measured in two varieties of electromagnetic calorimeter (see Fig. 3 ). Because virtual photons of mass M decay in times of order ℏ/ M to “di-lepton pairs” consisting of e+e− or μ + μ −, they are detected in PHENIX via charged particle spectrometers which specialize in electron or muon measurements.
