Measurement of the Width difference of $B_{d}$ mesons
We estimate \Delta Gamma_d/\Gamma_d, including 1/m_b contributions and part of the next-to-leading order QCD corrections, and find it to be around 0.3%. We show the methods to measure \Delta Gamma_d/\Gamma_d by using at least two different final states on the untagged B_d decay. The nonzero width di...
