Abstract

We determine the number of light neutrinos directly from data on (i) the production of W and Z bosons in pp collisions and (ii) deep-inelastic scattering of leptons on hydrogen and deuterium. Ambiguities related to the use of structure functions are avoided. We conclude that at 95% confidence level, N3 and m(top)60 GeV. N=4 is allowed if the fourth neutrino is accompanied by a heavy charged lepton lighter than MW.. AE
