$B \to D^{(*)} τ ν_{τ}$ decay properties with RIQ model

Sonali Patnaik, Lopamudra Nayak, Sanjay Kumar Swain

In this work we compute the branching fraction of $B \to D^{(*)} τ ν_{τ}$ and $B_{s} \to D_{s}^{(*)} τ ν_{τ}$ within the Relativistic Independent Quark Model, emphasizing the harmo…

Mass spectrum of S-wave mesons in the relativistic independent quark model

Lopamudra Nayak, Sonali Patnaik, Divyajyoti Pandey +1

The confining strength or model parameters and constituent quark masses are reparametrized for predicting the ground state meson masses. We analyzed these from the hyperfine splitt…

Study of exclusive decays of \texorpdfstring{ $B_{s} \to ψ (1 S, 2 S) K_{s}$ }{Lg} and \texorpdfstring{ $B_{s} \to η_{c} (1 S, 2 S) K_{s}$ }{Lg}

Lopamudra Nayak, Sonali Patnaik, Priyanka Sadangi +1

We analyze the exclusive two-body nonleptonic decays of $B_{s}$ meson to ground as well as radially excited $2 S$ charmonium state with a light meson $K_{s}$ , induced by the $b\to c\bar…

Study of angular observables in exclusive semileptonic $B_{c}$ decays

Sonali Patnaik, Lopamudra Nayak, Priyanka Sadangi +2

In this work, we investigate angular observables such as the longitudinal polarization of charged leptons, $τ$ -polarization, and forward-backward asymmetry in semileptonic $B_{c}$ de…

Assessing Lepton Flavor Universality Violations in Semileptonic Decays

Sonali Patnaik, Lopamudra Nayak, Rajeev Singh

In light of recent measurements suggesting potential lepton flavor universality violations in semileptonic decays at collider experiments, this article provides a concise study of…

The nonleptonic decays of $b$ -flavored mesons to $S$ -wave charmonium and charm meson states

Kalpalata Dash, Lopamudra Nayak, P. C. Dash +3

The detection of radially excited heavy meson \\states in recent years and measurement of heavy meson decays, particularly $B_{c}^{+} \to J / ψ D_{s}^{+}$ and $B_{c}^{+} \to J / ψ D_{s}^{*+}$ , by the LH…
