PROBING CKM PARAMETERS THROUGH UNITARITY, ε_K AND ΔM_Bd,s

Abstract

A recently carried out unitarity based analysis [1,2] involving the evaluation of Jarlskog's rephasing invariant parameter J as well as the evaluation of the angles α, β and γ of the unitarity triangle is extended to include the effects of This range of sin2β is in agreement with the earlier result of BELLE, however has marginal overlap only with the lower limit of recent BELLE results. Interestingly, our results indicate that the lower limit of δ is mostly determined by unitarity, while the upper limit is governed by constraints from ∆m d .
