Signatures of Invisible Fermions in $Λ_{b}^{0} \to Λ_{c}^{+} ℓ^{-} X ˉ_{inv}$ Decays

Shantanu Sahoo, Soumitra Nandi

We investigate the effects of a massive invisible fermion in $Λ_{b}^{0} \to Λ_{c}^{+} ℓ^{-} X ˉ_{inv}$ decays using a model-independent weak effective theory. Through a comprehens…

Precision Study of Semileptonic and Non-Leptonic $B_{c}$ Decays to $η_{c}$ and P Wave Charmonia

Aritra Biswas, Soumitra Nandi, Shantanu Sahoo

We analyse semileptonic and non-leptonic decays of the $B_{c}$ meson into P wave charmonium states. The analytic expressions for the transition form factors are taken from NRQCD, whi…

A Comprehensive Analysis of $B_{s} \to D_{s}^{**} ℓ ν_{ℓ}$ Decays Within and Beyond the Standard Model

Karthik Jain, Tarun Kumar, Barilang Mawlong +1

We examine the exclusive semileptonic decays $B_{s} \to D_{s}^{**} ℓ ν_{ℓ}$ , with $D_{s}^{**} =$ ${D_{s 0}^{*}, D_{s 1}^{*}, D_{s 1}, D_{s 2}^{*}}$ , within the Standard Model and beyo…

Probing Invisible Fermions in $B \to D^{*} ℓ X_{inv}$ via Angular Observables

Lipika Kolay, Soumitra Nandi, Shantanu Sahoo

Semileptonic decays $B \to D^{*} ℓ X_{inv}$ provide a sensitive probe of light invisible particles, such as sterile neutrinos or dark-sector fermions. Within a general we…

Probing Light Dark Fermions in $B \to D^{(*)} ℓ X_{inv}$ via Rate Distributions

Lipika Kolay, Soumitra Nandi, Shantanu Sahoo +1

Experimental analyses of the semileptonic decays $B \to D^{(*)} ℓ ν ˉ$ typically rely on the assumption that the missing energy originates from a massless neutrino, as predic…
