Dimension-eight operators in the weak OPE
Weak amplitude attenuation amplitude weak Hamiltonian separation
2014/12/22
We argue that there is a potential flaw in the standard treatment of weak decay amplitudes, including that of ǫ′/ǫ. We show that (contrary to conventional wisdom) dimension-eight operators d...
OPE, Heavy-Quark Mass, and Heavy-Meson Decay Constants from QCD Sum Rules
OPE Heavy-Quark Mass Heavy-Meson Decay Constants from QCD Sum Rules
2011/1/7
We present a sum-rule extraction of the decay constants of heavy-lightmesons from the two-point
correlator of pseudoscalar currents [1]. To this end, we compare the perturbative expansions for the co...
