A closer look at observables from exclusive semileptonic $B \to (π, ρ) ℓ ν_{ℓ}$ decays

Aritra Biswas, Soumitra Nandi

This article analyses the available inputs in $\btopilnu$ and $\btorholnu$ decays which include the measured values of differential rate in different $q^{2}$ -bins (lepton invariant m…

A closer look at the extraction of $∣ V_{u b} ∣$ from $B \to π l ν$

Aritra Biswas, Soumitra Nandi, Sunando Kumar Patra +1

To extract the Cabibbo-Kobayashi-Maskawa (CKM) matrix element $∣ V_{u b} ∣$ , we have re-analyzed all the available inputs (data and theory) on the $B \to π l ν$ decays including the newly…

Exhaustive Model Selection in $b \to s ℓℓ$ Decays: Pitting Cross-Validation against AIC $_{c}$

Srimoy Bhattacharya, Aritra Biswas, Soumitra Nandi +1

In the light of recent data, we study the new physics effects in the exclusive $b \to s ℓ^{+} ℓ^{-}$ decays from a model independent perspective. Different combinations of the dim…

An in-depth analysis of $b \to c (s)$ semileptonic observables with possible $μ - τ$ mixing

Srimoy Bhattacharya, Aritra Biswas, Zaineb Calcuttawala +1

In a couple of recent publications ( arXiv:1706.08437 and arXiv:1712.01593 ), the authors attempted to achieve simultaneous explanation of the persistent flavor anomalies in $b\to…

Collider signature of $V_{2}$ Leptoquark with $b \to s$ flavour observables

Aritra Biswas, Avirup Shaw, Abhaya Kumar Swain

The Leptoquark model has been instrumental in explaining the observed lepton flavour universality violating charged ( $b \to c$ ) and neutral ( $b \to s$ ) current anomalies that have be…

$b \to c l ν$ anomalies in light of vector and scalar interactions

Aritra Biswas

We perform a model independent analysis of the charged current $b \to c l ν$ anomalies under the presence of scalar and vector interactions. The analysis is carried out in two stages:…
