An $A_{4}$ -Symmetric Double Seesaw for Neutrino Masses and Mixing in Light of JUNO results

Swaraj Kumar Nanda, Maibam Ricky Devi, Chandini Dash +2

We discuss a double seesaw mechanism for generating light neutrino masses within the Standard Model extensions that include both right-handed neutrinos and extra gauge-singlet ster…

Exclusive nonleptonic Bc-meson decays to S-wave charmonium states

Lopamudra Nayak, P. C. Dash, Susmita Kar +1

We study the exclusive two-body nonleptonic $B_{c} \to X_{c c ˉ} M$ decays, where $X_{c c ˉ}$ is either a ground(1S) or a radially excited (2S or 3S) charmonium and $M$ is a pseu…

Lepton mass effects in exclusive semileptonic $B_{c}$ -meson decays

Lopamudra Nayak, Sonali Patnaik, P. C. Dash +2

In this work, we discuss exclusive semileptonic $B_{c}$ -meson decays: $B_{c} \to η_{c} (J / ψ) l ν$ and $B_{c} \to D (D^{*}) l ν$ in the framework of the relativistic independent quark(RIQ) model base…

Semileptonic $B_{c}$ meson decays to S-wave charmonium states

Sonali Patnaik, Lopamudra Nayak, P. C. Dash +2

We study the semileptonic decays of $B_{c}$ meson to S-wave charmonium states in the framework of relativistic independent quark model based on an average flavor-independent confinin…

Magnetic Dipole Transitions of $B_{c}$ and $B_{c}^{*}$ mesons in the Relativistic Independent Quark Model

Sonali Patnaik, P. C. Dash, S. Kar +2

We study M1-transitions involving mesons: $B_{c} (1 s)$ , $B_{c}^{*} (1 s)$ , $B_{c} (2 s)$ , $B_{c}^{*} (2 s)$ , $B_{c} (3 s)$ and $B_{c}^{*} (3 s)$ in the relativistic independent quark (RIQ) model based on a fla…
