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…

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…

Polarized $Λ_{b}$ baryon decay to $p π$ and a dilepton pair

Diganta Das, Ria Sain

The recent anomalies in $b \to s ℓ^{+} ℓ^{-}$ transitions could originate from some New Physics beyond the Standard Model. Either to confirm or to rule out this assumption, more tes…

Test of analyticity and unitarity for the pion form-factor data around the $ρ$ resonance

B. Ananthanarayan, Irinel Caprini, Diganta Das

High-statistics data on the $e^{+} e^{-} \to π^{+} π^{-}$ cross section and the pion vector form factor have been obtained recently by several collaborations. Unfortunately, there are some te…

The $Λ_{b} \to Λ^{*} (1520) (\to N K ˉ) ℓ^{+} ℓ^{-}$ decay at low-recoil in HQET

Diganta Das, Jaydeb Das

In this paper we discuss the Standard Model and new physics sensitivity of the $Λ_{b} \to Λ^{*} (1520) (\to N K ˉ) ℓ^{+} ℓ^{-}$ decay at low-recoil, where $ℓ^{\pm}$ are massive le…
