LCSR predictions for $B \to K$ Hadronic Matrix Elements

Dayanand Mishra

In this talk, I will present the calculation of LCSR predictions for the $B \to K$ Hadronic Matrix Elements (HME) at low $q^{2}$ using light meson distribution amplitudes. I will dis…

On the smallness of charm loop effects in $B \to K^{(*)} ℓℓ$ at low $q^{2}$ : light meson Distribution Amplitude analysis

Namit Mahajan, Dayanand Mishra

The non-local effects originating from the charm quark loops at dilepton invariant masses smaller than the charmonium threshold in $B \to K ℓℓ$ are evaluated with light meson…

$B \to X_{c (u)} ℓ ν ˉ_{ℓ} γ$ and determination of non-perturbative parameters

Namit Mahajan, Dayanand Mishra

This article explores the calculation of non-perturbative parameters present in the matrix element of semileptonic inclusive $B$ decays. These are important for the inclusive deter…

More on Denominator Regularization in Quantum Field Theory

Anshika Bansal, Namit Mahajan, Dayanand Mishra

Recently \cite{Horowitz:2022rpp,Horowitz:2022uak}, denominator regularisation (Den. Reg.) scheme has been proposed to handle divergences in quantum field theory. It is shown to yie…

$\frac{∣ V _{u b} ∣}{∣ V _{c b} ∣}$ and Quest for New Physics

Anshika Bansal, Namit Mahajan, Dayanand Mishra

Charged current semi-leptonic decays of $B$ -meson are important for a precise determination of the CKM elements. The CKM elements $∣ V_{u b} ∣$ and $∣ V_{c b} ∣$ show a discrepancy betwe…

On the Impact of Soft Photons on $B \to K ℓ^{+} ℓ^{-}$

Dayanand Mishra, Namit Mahajan

We give detailed results of $O (α)$ QED corrections (both real emission and virtual corrections) to $B \to K ℓ^{+} ℓ^{-}$ modes. Requiring the real emission to be gauge inv…
