Contribution of the Darwin operator to non-leptonic decays of heavy quarks
Abstract We compute the Darwin operator contribution ( 1 / m b 3 $$ 1/{m}_b^3 $$ correction) to the width of the inclusive non-leptonic decay of a B meson (B +, B d or B s ), stemming from the quark flavour-changing transition b → q 1 q ¯ 2 q 3 $$ {q}_1{\overline{q}}_2{q}_3 $$ , where q 1 , q 2 = u,...
