On the nonperturbative charm effects in inclusive B -> X_c lνdecays
I. I. Bigi, N. Uraltsev, R. Zwicky
We address the nonperturbative effects associated with soft charm quarks in inclusive B decays. Such corrections are allowed by the OPE, but have largely escaped attention so far.…

SU(3) Breaking of Leading--Twist K and K* Distribution Amplitudes - a Reprise
Patricia Ball, Roman Zwicky
We review the status of the leptonic decay constants f_K and f_K^{\parallel,\perp} of the K and K*, respectively, and the SU(3) breaking quantities a_1(K) and a_{1}^{\parallel,\per…
