Z. Hioki, ELECTRON P(T)-CUT EFFECTS ON LAMBDA(C) ENERGY ASYMMETRY IN POLARIZED-LAMBDA(B) DECAY TO LAMBDA(C) E(NU)OVER-BAR-E, Physical review. D. Particles and fields, 48(7), 1993, pp. 3404-3407
Electron p(t)-cut effects on the LAMBDA(c) energy spectrum are studied
in the decay LAMBDA(b)-->LAMBDA(c)enu(e)BAR where LAMBDA(b) is polari
zed along the direction of its motion. The differential width calculat
ed in the heavy quark effective theory is applied to the LAMBDA(c)-ene
rgy asymmetry introduced recently by Tanaka to probe the V, A structur
e of the b-c charged current. These effects are found to be significan
t and therefore it is indispensable to take them into account in actua
l analyses.
