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 QCD Static Energy using Optimal Renormalization and Asymptotic Padé-approximant Methods

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

The perturbative QCD static potential and ultrasoft contributions, which together give the static energy, have been calculated to three- and four-loop order respectively, by severa…

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…
