Abstract We present an extension of the SM involving three triplet fermions, one triplet scalar and one singlet fermion, which can explain both neutrino masses and dark matter. One triplet of fermions and the singlet are odd under a Z 2 symmetry, thu

In this work, we investigated mass ordering sensitivity using a combination of three experiments (ICAL, T2HK, and JUNO). All three differ in terms of baselines, energy range, and oscillation channels. All three have some limitations that can be addre

Abstract We explore invisible neutrino decay in which a heavy active neutrino state decays into a light sterile neutrino state and present a comparative analysis of two baseline options, 540 km and 360 km, for the ESSnuSB experimental setup. Our anal

Abstract In presence of non standard interactions (NSI), the solar neutrino data is consistent with two solutions, one close to the standard LMA solution with sin2 θ 12 ≃ 0.31 and another with sin 2 θ 12 D ≃ 0.69 = 1 − sin 2 θ 12 $$ {\sin}^2

Abstract Active-sterile neutrino mixing is known to affect the neutrino oscillation probabilities at both short as well as long-baselines. In particular, constraints on active-sterile neutrino oscillation parameters can be obtained from long-baseline

Abstract We explore the thermal light sterile neutrino situation from cosmological perspective in the $$\Lambda \text {CDM} + r_{0.05} + N_{\text {eff}} + m^{\text {eff}}_{\text {s}}$$ ΛCDM+r0.05+Neff+mseff model using combinations of latest data se

Abstract There is a proposal to send a neutrino beam from the Protvino accelerator complex located in Russia to the detector facility called ‘Oscillation Research with Cosmics in the Abyss’ (ORCA) in the Mediterranean sea to study neutrino oscill

Abstract The non-thermal dark matter (DM) production via the so-called freeze-in mechanism provides a simple alternative to the standard thermal WIMP scenario. In this work, we consider a popular U(1) B−L extension of the standard model (SM) in the

Abstract In this work, we explain three beyond standard model (BSM) phenomena, namely neutrino masses, the baryon asymmetry of the Universe and Dark Matter, within a single model and in each explanation the right handed (RH) neutrinos play the prime
