A massive right-handed sterile neutrino in three-body $B ˉ \to D^{*} ℓ^{-} N ˉ_{R}$ decays - a Monte Carlo simulation study

Bhubanjyoti Bhattacharya, Thomas E. Browder, Lucien M. Cremaldi +6

We investigate the differential decay distributions of $B ˉ \to D^{*} ℓ^{-} N ˉ_{R}$ , where $N_{R}$ is a heavy right-handed neutrino (RHN) and $ℓ = e, μ$ . We employ a newly de…

Response of Hellinger-distance based coherence to weak decoherence in two-flavor neutrino oscillations

Saurabh Rai, Nilakshi Das, Tejhas Kapoor

We evaluate the Hellinger-distance coherence of the two-flavor neutrino state subject to Lindblad damping of the mass-eigenstate interference term, and obtain a closed expression i…

Massive right-handed neutrinos in $B ˉ \to D^{*} τ X ˉ$ decay

Nilakshi Das, Alakabha Datta, Tejhas Kapoor +2

We explore signatures of a massive right-handed neutrino (RHN) in angular distributions of $B ˉ \to D^{*} (\to D π) τ (\to π ν_{τ}) X ˉ$ decays, where $X$ is an invisible state. W…

Blazars as a Potential Origin of the KM3-230213A Event

The KM3NeT Collaboration

The KM3NeT collaboration has reported the detection of the highest energy neutrino event observed to date. The energy of the event is of the order of 220 PeV hinting towards a neut…

wilson: A package for renormalization group running in the SMEFT with Sterile Neutrinos

Jason Aebischer, Tejhas Kapoor, Jacky Kumar

Sterile neutrinos are well-motivated beyond the Standard Model (BSM) particles. The Standard Model Effective Field Theory (SMEFT) augmented with these new fields is known as the $ν…

New physics searches via angular distributions of $B ˉ \to D^{*} (\to D π) τ (\to ℓ ν_{τ} ν ˉ_{ℓ}) ν ˉ_{τ}$ decays

Bhubanjyoti Bhattacharya, Thomas E. Browder, Alakabha Datta +3

The study of $B ˉ \to D^{*} τ ν ˉ_{τ}$ angular distribution can be used to obtain information about new physics (or beyond the Standard Model) couplings, which are motivated by…

New physics search via angular distribution of $B \to D^{*} ℓ ν_{ℓ}$ decay in the light of the new lattice data

Tejhas Kapoor, Zhuo-Ran Huang, Emi Kou

In this article, we investigate the potential of the angular distribution of the $B \to D^{*} ℓ ν_{ℓ}$ process to search for new physics signals. The Belle collaboratio…

New physics search via CP observables in $B_{s}^{0} \to ϕϕ$ decay with Chromomagnetic operators

Tejhas Kapoor

In this work, we investigate the time-dependent angular analysis of $B_{s}^{0} \to ϕϕ$ decay to search for new physics signals via CP-violating observables. We work with a new…
