N2 - We estimate ?Gd/Gd, including 1/mb contributions and part of the next-to-leading order QCD corrections. We find that adding the latter corrections decreases the value of ?Gd/Gd computed at the leading order by a factor of almost 2. We also show that under certain conditions an upper bound on the value of ?Gd/Gd in the presence of new physics can be derived. With the high statistics and accurate time resolution of the upcoming LHC experiment, the measurement of ?Gd seems to be possible. This measurement would be important for an accurate measurement of sin(2ß) at the LHC. In addition, we point out the possibility that the measurement of width difference leads to a clear signal for new physics.
