Constraint on rho-bar, eta-bar from B to K*pi

Michael Gronau, Dan Pirjol, Amarjit Soni +1

A linear CKM relation, $η ˉ = tan Φ_{3/2} (ρ ˉ - 0.24 \pm 0.03)$ , involving a $1 σ$ range for $Φ_{3/2}$ , $2 0^{\circ} < Φ_{3/2} < 11 5^{\circ}$ , is obtained from $B^{0} \to K^{*} π$ amplitudes m…

Studying New Physics Amplitudes in Charmless B_s Decays

Robert Fleischer, Michael Gronau

A method based on flavour SU(3) is proposed for identifying and extracting New Physics (NP) amplitudes in charmless $Δ S = 1$ $B_{s}$ decays using time-dependent CP asymmetries in these…

Direct CP Violation in B Decays

Michael Gronau

We discuss several aspects of direct CP asymmetries in B decays, which are very useful in spite of hadronic uncertainties in asymmetry calculations. 1) Asymmetries in decays to $D^…

Systematic Error on Weak Phase $γ$ from $B \to π^{+} π^{-}$ and $B \to K π$

Michael Gronau, Jonathan L. Rosner

When CP asymmetries in $B^{0} (t) \to π^{+} π^{-}$ are combined using broken flavor SU(3) with decay rates for $B^{+} \to K^{0} π^{+}$ and/or $B^{0} \to K^{+} π^{-}$ , one can obtain stringent limits on th…

CP violation in beauty decays

Michael Gronau

Precision tests of the Kobayashi-Maskawa model of CP violation are discussed, pointing out possible signatures for other sources of CP violation and for new flavor-changing operato…

Enhanced effects on extracting γfrom untagged B^0 and B_s decays

Michael Gronau, Yuval Grossman, Ze'ev Surujon +1

The weak phase γcan be determined using untagged B^0\to DK_S or B_s\to Dϕ, Dη^{(')} decays. In the past, the small lifetime difference y\equiv ΔΓ/(2Γ) has been neglected in B^0, wh…
