| dc.description | We estimate $\dg/Γ_d$, including $1/m_b$ contributions and part of the next-to-leading order QCD corrections. We find that adding the latter corrections decreases the value of $\dg/Γ_d$ 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 $\dg/Γ_d$ 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 $\dg$ seems to be possible. This measurement would be important for an accurate measurement of $\sin(2β)$ at the LHC. In addition, we point out the possibility that the measurement of the width difference leads to a clear signal for new physics. | |
