A STUDY OF THE K-PLUS LIFETIME AND THE LONGITUDINAL POLARIZATION OF THE MUON IN K-PLUS MUON-2 AND K-PLUS MUON-3 DECAY.
Abstract
In a counter experiment at the Princeton-Penn Accelerator, a precise measurement was made of the K-plus lifetime and the lifetime of the K-plus muon-2 decay mode. The longitudinal polarization of the muon in K-plus muon-2 decay and at two values of the muon energy in K-plus muon-3 decay was also measured. Lifetime data was analyzed with a view toward checking for deviations from a pure exponential decay law. No evidence was found for such deviations. The longitudinal polarization of the muon in K-plus muon-2 decay was found to be -1.01 = 0.12. For the longitudinal polarization of the muon in K-plus muon-3 decay, we found P=+0.7 = 0.6 at a muon energy of (191 = 4) Mev and P= -0.6 = 0.7 at (231 = 4) Mev. These data, taken together with other recent measurements of this polarization, are consistent with the constant form factor theory with Zeta = 0.5 and with a partially conserved strangeness changing vector current theory.
