Open Access item QCD duality analysis of B^0---B^0^- mixing

Authors:Pich, Antonio
Issue Date:19-May-1988

Citation:Physics Letters B 206(2): 322-326 (1988)
Abstract:Using finite energy sum rules, the hadronic matrix element of the AB= 2 operator governing the mixing between the B^0 and B^0^- mesons is evaluated. The result is very sensitive to the input value of the bottom quark mass. Allowing it to vary in the range mb = 4.70 +/- 0.14 GeV, one finds ~B |(raiz cuadrada |bb|)= 0.13 +/- 0.05 GeV.
