BOUNDS ON RIGHT-HANDED CURRENTS FROM A RELATIVE BETA-POLARIZATION MEASUREMENT WITH POLARIZED IN-107
Journal or Book Title
NUCLEAR PHYSICS A
The first measurements of the longitudinal polarization of positrons emitted by polarized 107In are reported. The positron polarization is deduced from the time-resolved decay spectrum of positronium hyperfine states. Our result is in agreement with the standard electro-weak model and provides a new lower limit for the mass of an eventual, predominantly right-handed charged W-gauge boson of 220 GeV/c2.
