Abstract

The measurement of sin2β\sin {2\beta} from BdJ/ψKsB_d \to J/\psi K_s does not resolve the discrete ambiguities in the angle β\beta. A measurement of cos2β\cos {2\beta} is therefore desirable.This talk is about measuring the CKM angle β(ϕ1)\beta(\phi_1) from various B decays to charm final states which also allow us a measurement of cos2β\cos {2\beta}.
