Light-cone sum rules with $B$ -meson distribution amplitudes for the $B \to p$ form factors in $B$ -mesogenesis models

Aritra Biswas, Alexander Khodjamirian, Ali Mohamed

New decay modes of $B$ -meson into a baryon and invisible dark antibaryon $I^¨$ are among the most distinctive signatures of the $B$ -mesogenesis scenario. We concentrate on the proto…

Impact on $L$ -observables of a new combined analysis of $B_{d, s} \to K^{(*)}$ form factors

Aritra Biswas, Nico Gubernari, Joaquim Matias +1

We explore the impact of a combined analysis of $B_{d, s} \to K^{(*)}$ form factors on a set of $L$ -observables. The $L$ -observables are constructed from ratios of branching fraction…

Penguin decays of B mesons

Aritra Biswas

We propose a set of optimized observables using penguin mediated $B ˉ_{d}$ and $B ˉ_{s}$ decays to $K^{(*)} K ˉ^{(*)}$ and $K^{*} I ¨ $ final states that exhibhit a reduced sensi…
