Renormalization group improved $m_{s}$ and $∣ V_{u s} ∣$ determination from hadronic $τ$ decays

B. Ananthanarayan, Diganta Das, M. S. A. Alam Khan

We determine the strange quark mass ( $m_{s}$ ) and quark mixing element $∣ V_{u s} ∣$ , and their joint determination from the Cabibbo suppressed hadronic $τ$ decays in various…

Prospects for precise predictions of $a_{μ}$ in the Standard Model

G. Colangelo, M. Davier, A. X. El-Khadra +79

We discuss the prospects for improving the precision on the hadronic corrections to the anomalous magnetic moment of the muon, and the plans of the Muon $g - 2$ Theory Initiative to…

Precise LHC limits on the $U_{1}$ leptoquark parameter space

Arvind Bhaskar, Diganta Das, Tanumoy Mandal +2

A TeV scale leptoquark (LQ) is one of the promising explanations of the recent anomalies in the semileptonic decays of $B$ mesons. Among the various LQs, the vector $U_{1}$ is c…

Sterile neutrinos in $Λ_{b}^{0} \to (Λ_{c}^{+}, p^{+}) ℓ_{1}^{-} ℓ_{2}^{-} ℓ_{3}^{+} ν$ decays

Diganta Das, Jaydeb Das

We study lepton number violating and lepton number conserving semi-leptonic decays of heavy baryons $Λ_{b}^{0}$ to three charged leptons and a neutrino. The decays occur through two in…

CP violation with GeV-scale Majorana neutrino in $Λ_{b} \to (Λ_{c}^{+}, p^{+}) π^{+} μ^{-} μ^{-}$ decays

Diganta Das, Jaydeb Das

We explore the possibility of CP violation in baryonic $Λ_{b} \to (Λ_{c}^{+}, p^{+}) π^{+} μ^{-} μ^{-}$ decays which are mediated by two Majorana sterile neutrino and are $∣Δ L ∣ = 2$ lepton number viola…

Precise limits on the charge- $2/3$ $U_{1}$ vector leptoquark

Arvind Bhaskar, Diganta Das, Tanumoy Mandal +2

The $U_{1}$ leptoquark is known to be a suitable candidate for explaining the semileptonic $B$ -decay anomalies. We derive precise limits on its parameter space relevant for the anoma…
