Semileptonic decays in the limit of a heavy daughter quark

  • 1. Department of Physics, University of Alberta, Edmonton, Alberta, T6G 2G7 (Canada)

Description

The rate of the semileptonic decay b→clν is calculated with O(αs2) accuracy, as an expansion around the limit of equal masses of the b and c quarks. Recent results obtained around the limit of the c-quark much lighter than b are confirmed. Details of the new expansion method are described.
