S. Aid et al., MEASUREMENT OF THE Q(2) DEPENDENCE OF THE CHARGED AND NEUTRAL-CURRENTCROSS-SECTIONS IN E(+ -)P SCATTERING AT HERA/, Physics letters. Section B, 379(1-4), 1996, pp. 319-329
The Q(2) dependence and the total cross sections for charged and neutr
al current processes are measured in e(+/-)p reactions for transverse
momenta of the outgoing lepton larger than 25 GeV. Comparable size of
cross sections for the neutral current process and for the weak charge
d current process are observed above Q(2) approximate to 5000 GeV2. Us
ing the shape and magnitude of the charged current cross section we de
termine a propagator mass of m(w) = 84(-7)(+10) GeV.
