Description
We present a calculation of 1/m2b corrections to the lifetime differences
of Bs mesons in the heavy-quark expansion. We find that they are small
to significantly affect \Delta\GammaB_s and present the result
for lifetime difference including non-perturbative 1/mb and 1/m2b
corrections. We also analyze the generic B = 1 New Physics contributions
to the lifetime difference of Bs mesons and provide several examples.
