Abstract
The most precise upper limits for the muonneutrino mass m vμ have been obtained by measuring the muon momentum p μ+ in pion decay π + →μ + ν μ at rest. The current result for the squared neutrino mass, m νμ 2 = -0.154 ± 0.045 MeV 2, negative by 3.4 standard deviations, indicates that the experimental value for at least one of the three quantities used in the (m νμ 2)- derivation (p μ +, m π+ , m μ +) is wrong.
