$B \to K_{2}^{*} (1430) ℓ^{+} ℓ^{-}$ distributions in Standard Model at large recoil

Diganta Das, Bharti Kindra, Girish Kumar +1

We study the rare decay $B \to K_{2}^{*} (1430) (\to K π) ℓ^{+} ℓ^{-}$ in the Standard Model and beyond. Working in the transversity basis, we exploit the relations between the heavy-to…

Spectral function and dilepton rate from a strongly magnetised hot and dense medium in the light of mean field models

Chowdhury Aminul Islam, Aritra Bandyopadhyay, Pradip K. Roy +1

We have calculated the electromagnetic spectral function (SF) vis-à-vis the dilepton rate (DR) by evaluating the one-loop photon polarisation tensor for a strongly magnetised hot a…

Scope of strongly self-interacting thermal WIMPs in a minimal $U (1)_{D}$ extension and its future prospects

Rahool Kumar Barman, Biplob Bhattacherjee, Arindam Chatterjee +2

In this work we have considered a minimal extension of Standard Model by a local $U (1)$ gauge group in order to accommodate a stable (fermionic) Dark Matter (DM) candidate. We have…

Fat Jet Signature of a Heavy Neutrino at Lepton Collider

Sabyasachi Chakraborty, Manimala Mitra, Sujay Shil

We explore the discovery prospect of a very heavy neutrino at the proposed $e^{+} e^{-}$ collider for two different c.m.energies $s = 1.4$ TeV and 3 TeV. We consider production of…

Unearthing the electroweak structure of warped 5D models

Abhishek M. Iyer, K. Sridhar

Heavy charged bosons, with masses in the range of a few TeV, are a characteristic of warped extra-dimensional models with bulk gauge fields. Rendering the latter consistent with el…

Tensions between the appearance data of T2K and NOvA

Mohammad Nizam, Suman Bharti, Suprabh Prakash +2

The long baseline neutrino experiments, T2K and NOvA, have taken significant amount of data in each of the four channels: (a) $ν_{μ}$ disappearance, (b) $ν ˉ_{μ}$ disappearance (c) $…

Mixed WIMP-axion dark matter

Suman Chatterjee, Anirban Das, Tousik Samui +1

We study the experimental constraints on a model of a two-component dark matter, consisting of the QCD axion, and a scalar particle, both contributing to the dark matter relic abun…

Normal-mode Analysis for Collective Neutrino Oscillations

Sagar Airen, Francesco Capozzi, Sovan Chakraborty +3

In an interacting neutrino gas, collective modes of flavor coherence emerge that can be propagating or unstable. We derive the general dispersion relation in the linear regime that…

Collisional triggering of fast flavor conversions of supernova neutrinos

Francesco Capozzi, Basudeb Dasgupta, Alessandro Mirizzi +2

Fast flavor conversions of supernova neutrinos, possible near the neutrinosphere, depends on an interesting interplay of collisions and neutrino oscillations. Contrary to naive exp…

Clockworked VEVs and Neutrino Mass

Avik Banerjee, Subhajit Ghosh, Tirtha Sankar Ray

In this paper we present an augmented version of the Abelian scalar clockwork model to generate geometrically suppressed vacuum expectation values (vev) of the pseudo Nambu-Goldsto…

Reconciling $B$ -decay anomalies with neutrino masses, dark matter and constraints from flavour violation

Chandan Hati, Girish Kumar, Jean Orloff +1

Motivated by an explanation of the $R_{K^{(*)}}$ anomalies, we propose a Standard Model extension via two scalar SU(2) $_{L}$ triplet leptoquarks and three generations of triplet Majo…

A few moments to diagnose fast flavor conversions of supernova neutrinos

Basudeb Dasgupta, Alessandro Mirizzi, Manibrata Sen

Neutrinos emitted from a supernova may undergo flavor conversions almost immediately above the core, with possible consequences for supernova dynamics and nucleosynthesis. However,…

Sterile Neutrinos with Secret Interactions -- Cosmological Discord?

Xiaoyong Chu, Basudeb Dasgupta, Mona Dentler +2

Several long-standing anomalies from short-baseline neutrino oscillation experiments -- most recently corroborated by new data from MiniBooNE -- have led to the hypothesis that ext…

Probing the scale of non-commutativity of space

Pulkit S. Ghoderao, Rajiv V. Gavai, P. Ramadevi

Examining quantum electrodynamics in non-commutative (NC) spaces along with composite operators in these spaces, we show that i) any charge g for a fermion matter field is allowed…

Observationally inferred dark matter phase-space distribution and direct detection experiments

Sayan Mandal, Subhabrata Majumdar, Vikram Rentala +1

We present a detailed analysis of the effect of an observationally determined dark matter (DM) velocity distribution function (VDF) of the Milky Way (MW) on DM direct detection rat…

Pinning down Anomalous $W W γ$ Couplings at the LHC

Disha Bhatia, Ushoshi Maitra, Sreerup Raychaudhuri

We make a careful analysis of $W^{\pm} γ$ production at the LHC, identifying the $W^{\pm}$ through leptonic decays, with a view to exploring the sensitivity of the machine to anomalous…

Active-sterile neutrino oscillations at INO-ICAL over a wide mass-squared range

Tarak Thakore, Moon Moon Devi, Sanjib Kumar Agarwalla +1

We perform a detailed analysis for the prospects of detecting active-sterile oscillations involving a light sterile neutrino, over a large $Δ m_{41}^{2}$ range of $1 0^{- 5}$ eV $^{2}$ to…
