Comment on "QCD-factorization amplitudes from flavour symmetries: beyond the $S U (3)$ symmetric case''

Bhubanjyoti Bhattacharya, David London

Recently, a fit to $B \to P P$ decays ( $P \in {I ¨ , K, I^\cdot, I^\cdot^{'}}$ ) was performed (arXiv:2604.19612, "QCD-factorization amplitudes from flavour symmetries: beyond the $S U (3)$ symmetr…

Axion-like particles and sterile neutrinos solve the $B \to K ν ν ˉ$ and $B \to π K$ puzzles

Bhubanjyoti Bhattacharya, Alakabha Datta, Girish Kumar +1

The recent measurement of the branching ratio of $B^{+} \to K^{+} + inv$ (where ``inv'' denotes invisible states) by the Belle II collaboration is enhanced relative to the sta…

New physics searches via angular distributions of $B ˉ \to D^{*} (\to D I ¨ ) I ¨ (\to ℓ I^½_{I ¨} I^ˉ ½_{ℓ}) I^ˉ ½_{I ¨} $ decays

Bhubanjyoti Bhattacharya, Thomas E. Browder, Alakabha Datta +3

The study of $B ˉ \to D^{*} I ¨ I^ˉ ½_{I ¨} $ angular distribution can be used to obtain information about new physics (or beyond the Standard Model) couplings, which are motivated…

The Deconstruction of Flavor in the Privately Democratic Higgs Sector

Bhubanjyoti Bhattacharya, Suneth Jayawardana, Nausheen R. Shah

The Standard Model (SM) of particle physics fails to explain the observed hierarchy in fermion masses or the origin of fermion-flavor structure. We construct a model to explain the…

Anomalies in Hadronic $B$ Decays: an Update

Bhubanjyoti Bhattacharya, Marianne Bouchard, Luke Hudy +3

Recently, $B \to P P$ decays ( $B = {B^{0}, B^{+}, B_{s}^{0}}$ , $P = {I ¨ , K}$ ) were analyzed under the assumption of flavor SU(3) symmetry (SU(3) $_{F}$ ). Although the individual fits to $…

Flavor Violations in $B$ -Mesons within Non-Minimal SU(5)

Bhubanjyoti Bhattacharya, Alakabha Datta, Gaber Faisel +2

Recent anomalies in $B$ -meson decays, such as deviations in $R_{D^{(*)}}$ and $B \to K I^½ I^ˉ ½$ , suggest possible lepton flavor universality violation and new exotic interactions.…
