We investigate the two main uncertainties on the extraction of the nonperturbative matrix elements Λ̄ and λ1 from moments of the inclusive rare FCNC decay B → Xsγ. The first one is due to unknown matrix elements of higher dimensional operators which are estimated by varying the matrix elements in a range as suggested by dimensional analysis. The effect of… (More)
