A global analysis of $B ˉ \to D P$ and $B ˉ \to D ˉ P$ decays

Bhubanjyoti Bhattacharya, Rida Boumris, David London

Recently, a fit to the 10 measured branching ratios of $B ˉ \to D P$ decays ( $B = {B^{+}, B^{0}, B_{s}^{0}}$ , $D = {D^{0}, D^{+}, D_{s}^{+}}$ , $P \in {π, K}$ ) was performed under the a…

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 ( $P \in {π, K, η, η^{'}}$ ) was performed (arXiv:2604.19612, "QCD-factorization amplitudes from flavour symmetries: beyond the $S U (3)$ symmetric…

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…

Isospin-based EWP-tree Relations

Bhubanjyoti Bhattacharya, Marianne Bouchard, Alexandre Jean +2

In 1998, it was shown that, if flavor SU(3) symmetry [SU(3) $_{F}$ ] is assumed in charmless $B \to P P$ decays ( $P$ is a light pseudoscalar meson), some reduced matrix elements involvi…

Anomalies in Hadronic $B$ Decays: an Update

Bhubanjyoti Bhattacharya, Marianne Bouchard, Luke Hudy +3

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

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…

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 $B \to K ν ν ˉ$ , suggest possible lepton flavor universality violation and new exotic interactions. I…

New physics searches via angular distributions of $B ˉ \to D^{*} (\to D π) τ (\to ℓ ν_{τ} ν ˉ_{ℓ}) ν ˉ_{τ}$ decays

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

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

Quasielastic Lepton-Nucleus Scattering and the Correlated Fermi Gas Model

Gil Paz

The future neutrino research program will require improved precision. A major source of uncertainty is the interaction of neutrinos with nuclei that serve as targets for such exper…

Neutrino Nonstandard Interactions and Lepton Flavor Universality violation at SND@LHC via charm production

Bhubanjyoti Bhattacharya, Alakabha Datta, Elena Graverini +3

In this work, we explore the effect of neutrino nonstandard interactions (NSI) involving the charm quark at SND@LHC. Using an effective description of new physics in terms of four-…

Anomalies in Hadronic $B$ Decays

Raphaël Berthiaume, Bhubanjyoti Bhattacharya, Rida Boumris +3

In this paper, we perform fits to $B \to P P$ decays, where $B = {B^{0}, B^{+}, B_{s}^{0}}$ and the pseudoscalar $P = {π, K}$ , under the assumption of flavor SU(3) symmetry [SU(3) $_{F}$ ].…
