Next-to-Leading Order QCD Corrections to the Lifetime Difference of $B_s$ Mesons
We compute the QCD corrections to the decay rate difference in the B_s-\bar{B}_s system, \Delta\Gamma_{B_s}, in the next-to-leading logarithmic approximation using the heavy quark expansion approach. Going beyond leading order in QCD is essential to obtain a proper matching of the Wilson coefficient...
