Subleading corrections to semileptonic Λc decays
Abstract
The semileptonic decay Λc → Λℓ ν is considered in the framework of heavy quark effective theory beyond the leading order in the 1/ mc expansion. According to our estimate, thepolarization variable will receive only very small corrections such that αΛc ⩽ -0.95.
