Vub, Vcb and Decay Constants in Effective Field Theory of Heavy Quarks
Abstract
A new framework of heavy quark effective field theory (HQEFT) is studied and compared with the usual heavy quark effective theory (HQET). |Vub|, |Vcb| and heavy meson decay constants are extracted in the new framework. HQEFT can yield reasonable results for both exclusive and inclusive decays.
