Soft photon corrections in $B \to K^{()} ℓ^{+} ℓ^{-}$ and $Λ_{b} \to Λ^{()} ℓ^{+} ℓ^{-}$ decays

Debajyoti Choudhury, Diganta Das, Jaydeb Das

We calculate QED corrections to the semileptonic decays $H_{1} \to H_{2} ℓ^{+} ℓ^{-}$ where $ℓ = e, μ$ and $H_{1, 2}$ are hadrons. The soft and/or collinear divergences are regulated i…

Veltman Criteria in Beyond Standard Model Effective Field Theory of Complex Scalar Triplet

Jaydeb Das, Nilanjana Kumar

The Higgs mass is not protected by any symmetry in the Standard Model. Hence, the self-energy corrections to the Higgs mass become large due to the quadratic divergence terms. Velt…

Study of entropy production due to electroweak phase transition in $Z_{2}$ symmetric extension of the Standard Model

Arnab Chaudhuri, Jaydeb Das

In this work we consider the simple $Z_{2}$ symmetric extension to the Standard Model (SM) and proceed to study the nature of electroweak phase transition (EWPT) in the early univers…

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…

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…
