Decay matrix of B- B ¯ $$ \overline{B} $$ mixing: mixing of dimension-seven operators into dimension-six operators under renormalization
Abstract The precise measurement of the width difference ∆Γ s among the mass eigenstates of the B s - B ¯ s $$ {\overline{B}}_s $$ system requires the calculation of the corresponding decay matrix to order α s /m b . QCD corrections to power-suppressed terms in the Heavy Quark Expansion involve the...
