Improved factorization for threshold resummation in heavy quark to heavy quark decays
Abstract We consider the resummation of soft-gluon effects in heavy quark to heavy quark decays, namely the processes $$Q_1 \rightarrow Q_2 \, + \, \mathrm {(non\,QCD\, partons)}$$ Q 1 → Q 2 + ( non QCD partons ) , where $$Q_1$$ Q 1 and $$Q_2$$ Q 2 are two different heavy quarks. We construct a new...
