Abstract
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.
