Abstract

The first measurements of the longitudinal polarization of positrons emitted by polarized107In are reported. The positron polarization is deduced from the time-resolved decay spectrum of positronium hyerfine states. Our result is in agreement with the standard electroweak model and provides a new lower limit for the mass of an eventual, predominantly right-handed charged W gauge boson of 220 GeV/c 2.
