$β(ϕ_1)$ from $ B $ Decays to Charm
Abstract
Description
The measurement of $\sin {2β}$ from $B_d \to J/ψK_s$ does not resolve the discrete ambiguities in the angle $β$. A measurement of $\cos {2β}$ is therefore desirable.This talk is about measuring the CKM angle $β(ϕ_1)$ from various B decays to charm final states which also allow us a measurement of $\cos {2β}$.
