    • Running-coupling effects in the triple-differential charmless semileptonic decay width. 

      Gambino, Paolo; Gardi, Einan; Ridolfi, Giovanni (High Energy Physics, Cavendish Laboratory, University of Cambridge, 2006-10)
      We compute the fully–differential ¯B → Xul¯ν decay width to all orders in perturbation theory in the large–β0 limit. Each of the five structure functions that build the hadronic tensor is expressed as a Borel integral, ...
