Measurement of $γ$ from three-body B decays

Bhubanjyoti Bhattacharya, Maxime Imbeault, David London

Using the BaBar measurements of the Dalitz plots for the decays $B^{0} \to K^{+} π^{0} π^{-}$ , $B^{0} \to K^{0} π^{+} π^{-}$ , $B^{+} \to K^{+} π^{+} π^{-}$ , $B^{0} \to K^{+} K^{0} K^{-}$ , and $B^{0} \to K^{0} K^{0} K ˉ^{0}$ …

Searching for New Physics with bbar -> sbar Bs -> V_1 V_2 Penguin Decays

Bhubanjyoti Bhattacharya, Alakabha Datta, Murugeswaran Duraisamy +1

We present the most general (six-helicity) angular analysis of Bs -> V_1 (-> P_1P'_1) V_2 (-> P_2P'_2) (V_i is a vector meson, and P_i, P'_i are pseudoscalars). We focus on final s…

CP asymmetries in three-body B+- decays to charged pions and kaons

Bhubanjyoti Bhattacharya, Michael Gronau, Jonathan L. Rosner

CP asymmetries have been measured recently by the LHCb collaboration in three-body $B^{+}$ decays to final states involving charged pions and kaons. Large asymmetries with opposite s…

Z-pole observables in an effective theory

Debajyoti Choudhury, Anirban Kundu, Pratishruti Saha

There are two Z-peak observables related to the pair production of bottom quarks that show a deviation of about 2.5σ each from Standard Model expectations. While the discrepancy in…

Extraction of the CP-violating phase $γ$ using $B \to K π π$ and $B \to K K K ˉ$ decays

Bhubanjyoti Bhattacharya, Maxime Imbeault, David London

Using the B{\sc a}B{\sc ar}\ measurements of the Dalitz plots for $B^{0} \to K^{+} π^{0} π^{-}$ , $B^{0} \to K^{0} π^{+} π^{-}$ , $B^{+} \to K^{+} π^{+} π^{-}$ , $B^{0} \to K^{+} K^{0} K^{-}$ , and $B^0 \to K^0 K^0 {\bar K…

Shift in weak phase $γ$ due to CP asymmetries in $D$ decays to two pseudoscalar mesons

Bhubanjyoti Bhattacharya, David London, Michael Gronau +1

A difference of several tenths of a percent has been observed between the direct CP asymmetries of $D^{0} \to K^{+} K^{-}$ and $D^{0} \to π^{+} π^{-}$ . It has been noted recently that CP asymmetri…
