Constraining the heavy leptophilic neutral gauge bosons through the , , and decays
Bibhabasu De, Amitabha Dey
We consider the hypothetical possibility of neutral gauge bosons () with flavor-specific leptophilic couplings. For such New Physics (NP) interactions, the current experi…
Exploring the Null Results in the Direct Detection Experiments, and Neutrino Mass in an Extended Model Constrained through the Decays
Bibhabasu De
The Direct Detection~(DD) experiments are vital for probing the particle nature of Dark Matter~(DM). However, in the absence of a scattering event, DD searches result in stringent…
A New Evidence of Interplay Between Tetrahedral and Octahedral Symmetries and Symmetry Breaking: Exotic Rotational Bands in Sm
S. Basak, D. Kumar, T. Bhattacharjee +30
We report on an experimental evidence for a new, second tetrahedral band in Sm. It was populated via fusion evaporation reaction, $^{150}{\rm Nd}(α, 2n)^…
Direct Measurement of Dark Matter Mass through the Scattering of a High-Energy Matter Beam
Bibhabasu De
The traditional methods of estimating the Dark Matter (DM) mass scale crucially depend on the assumptions about the interaction mechanism between the DM and the Standard Model (SM)…
The Revival of : A Natural Solution for with a Sub-GeV Dark Matter
Bibhabasu De
The experiments searching for a hidden gauge sector with a leptophilic neutral gauge boson have already ruled out as a feasible extension of the Standard Model (SM…
Systematic study of cross section for proton-induced reactions on Neodymium up to 65 MeV using TALYS-1.96 code
A. Saha
Systematic study of theoretical estimation of nuclear cross section of charged particle induced reactions on rare earth nuclei has been carried out. The production cross section of…
Determination of electron screening potential of 6 Li(p,α)3 He reaction using MultiLayer Perceptron based neural network
D. Chattopadhyay
Background: Understanding the nuclear reactions between light charged nuclei at sub-coulomb energy region holds significant importance in several astrophysical processes. Determina…
Direct production of SM-singlet scalars at the muon collider
Bibhabasu De
The present work proposes a minimal extension of the Standard Model~(SM) where a gauge-singlet scalar~() can be directly produced at the muon colliders without relying on its mi…
Critical analysis of multiple reentrant localization in an antiferromagnetic helix with transverse electric field: Hopping dimerization-free scenario
Sudin Ganguly, Sourav Chattopadhyay, Kallol Mondal +1
Reentrant localization (RL), a recently prominent phenomenon, traditionally links to the interplay of staggered correlated disorder and hopping dimerization, as indicated by prior…
Revisiting the Scalar Leptoquark () Model with the Updated Leptonic Constraints
Bibhabasu De
The Standard Model, if extended to the energy scale of TeV, the known particle spectrum could be augmented with a scalar leptoquark. Within this minimally extended…
AstroSat observation of rapid Type-I thermonuclear burst from the low mass X-ray binary GX 3+1
Ankur Nath, Biplob Sarkar, Jayashree Roy +1
We report the results of an observation of low mass X-ray binary GX 3+1 with {\it AstroSat}'s Large Area X-ray Proportional Counter (LAXPC) and Soft X-ray Telescope (SXT) instrumen…
Critical analysis of the re-entrant localization transition in a one-dimensional dimerized quasiperiodic lattice
Shilpi Roy, Sourav Chattopadhyay, Tapan Mishra +1
A re-entrant localization transition has been predicted recently in a one-dimensional quasiperiodic lattice with dimerized hopping between the nearest-neighbour sites (Phys. Rev. L…
A stellar constraint on Eddington-inspired Born-Infeld gravity from cataclysmic variable binaries
Pritam Banerjee, Debojyoti Garain, Suvankar Paul +2
Eddington-inspired Born-Infeld gravity is an important modification of Einstein's general relativity, which can give rise to non-singular cosmologies at the classical level, and av…
Constraining modified gravity from tidal phenomena in binary stars
Pritam Banerjee, Debojyoti Garain, Suvankar Paul +2
In beyond-Horndeski theories of gravity, the Vainshtein screening mechanism might only be partially effective inside stellar objects. This results in a modification of the pressure…
Tidal disruption near black holes and their mimickers
Pritam Banerjee, Suvankar Paul, Rajibul Shaikh +1
Black holes and wormholes are solutions of Einstein's field equations, both of which, from afar, look like a central mass. We show here that although at large distances both behave…
Effect of magnetic flux advection on the dynamics of shock in accretion flow around a rotating black hole
Biplob Sarkar, Anjali Rao
We investigate the dynamical behaviour of a magnetized, dissipative, accretion flow around a rapidly rotating black hole. We solve the magnetohydrodynamic equations and calculate t…
Whether Lyra's Manifold Itself is a Hidden Source of Dark Energy
Kangujam Priyokumar Singh, Koijam Manihar Singh, Mahbubur Rahman Mollah
In the course of investigation of some interesting cosmic string universes in the five dimensional Lyra manifold it is excitingly found that the geometry itself of Lyra manifold be…
Standing shocks in magnetized advection accretion flows onto a rotating black hole
Santabrata Das, Biplob Sarkar
We present the global structure of magnetized advective accretion flow around the rotating black holes in presence of dissipation. By considering accretion flow to be threaded by t…
A re-examination of real interest parity in CEECs using old and new generations of panel unit root tests
Claudiu Tiberiu Albulescu, Dominique Pepin, Aviral Kumar Tiwari
This study applies old and new generations of panel unit root tests to test the validity of long-run real interest rate parity (RIP) hypothesis for ten Central and Eastern European…
