Abstract
Positron asymmetry in the decay of muons produced in K{sup +} {yields} {mu}{sup +}{nu} has been precisely measured in a search for right-handed currents. A novel technique utilizing a `K{sub {mu}2} muon beam` from the at-rest decay of positive kaons in a primary proton-beam target was employed. A limit of |{xi}P{sub {mu}}| > 0.990 (90%C.L.) was obtained from the energy-integrated positron asymmetry observed in muon spin precession under a transverse magnetic field. This limit sets a new constraint on the second weak boson mass (M{sub W2}) as well as the Cabibbo angle of the right-handed sector. (author).
