The $ΔB = - ΔQ$ transitions and $B_d \leftrightarrow \bar B_d$ oscillations
Abstract
Description
We estimate the product of the relative strength of the $ΔB = -ΔQ$ amplitude in the decay $B_d^0 \rightarrow D^{*} \ell \bar ν_{\ell }$ and the width-difference parameter $y$. For this we have used the data on time-dependence of $B_{d}^0\bar B_{d}^0$ oscillations in Z decays and the fraction of like-sign dilepton events at the $Υ(4S)$.
