S. Matsumoto et al., HEAVY-QUARK POLARIZATION AND ENERGY-SPECTRA OF DECAY PRODUCTS IN SEMILEPTONIC DECAYS, International journal of modern physics A, 8(6), 1993, pp. 1153-1179
We calculate in the free quark model energy distributions of final lep
ton and quark pairs from c and b quark semileptonic decays in e-e+ col
liders. Polarizations and spin-spin correlations of heavy quark pair a
re discussed, which will test the vector and axial vector couplings of
the Weinberg-Salam model especially near the Z peak.
