We present the results based on the optical -band polarization observations of 280 stars distributed towards the dark globule LDN\,1225. {\it Gaia} data release 2 parallaxes alo…
Study in the noncanonical domain of Goldstone inflation
Sukannya Bhattacharya, Mayukh R. Gangopadhyay
Recent observations of the cosmic microwave background (CMB) indicate that a successful theory of cosmological inflation needs to have flat potential of the inflaton scalar field.…
Heavy quark diffusion in a Polyakov loop plasma
Balbeer Singh, Aman Abhishek, Santosh K Das +1
We calculate the transport coefficients, drag and momentum diffusion, of a heavy quark in a thermalized plasma of light quarks in the background of Polyakov loop. Quark thermal mas…
Leptoquark solution for both the flavor and ANITA anomalies
Bhavesh Chauhan, Subhendra Mohanty
The ANITA experiment has seen anomalous Earth emergent showers of EeV energies which cannot be explained with Standard Model interactions. In addition, tests of lepton flavor unive…
Anatomy of Heavy Gauge Bosons in a Left-Right Supersymmetric Model
Biplob Bhattacherjee, Najimuddin Khan, Ayon Patra
We perform a detailed study of the various decay channels of the heavy charged and neutral gauge bosons ( and respectively) in a left-right supersymmetric (LRSUSY) frame…
Generalized binomial state: Nonclassical features observed through various witnesses and a measure of nonclassicality
Kathakali Mandal, Nasir Alam, Amit Verma +2
Experimental realization of various quantum states of interest has become possible in the recent past due to the rapid developments in the field of quantum state engineering. Noncl…
Collider signature of Leptoquark with flavour observables
Aritra Biswas, Avirup Shaw, Abhaya Kumar Swain
The Leptoquark model has been instrumental in explaining the observed lepton flavour universality violating charged () and neutral () current anomalies that have be…
Probing vorticity in heavy ion collision with dilepton production
Jitesh R Bhatt, Hiranmaya Mishra, Balbeer Singh
We study the effect of vorticity present in heavy ion collisions (HICs) on the temperature evolution of hot quark-gluon plasma in the presence of spin-vorticity coupling. The initi…
Why the angular distribution of the top decay lepton is unchanged by anomalous coupling
Rohini M. Godbole, Michael E. Peskin, Saurabh D. Rindani +1
We give a simple physical argument to understand the observation that the angular distribution of the top decay lepton depends only on the polarisation of the top and is independen…
NMR studies of quantum chaos in a two-qubit kicked top
V R Krithika, V S Anjusha, Udaysinh T. Bhosale +1
Quantum chaotic kicked top model is implemented experimentally in a two qubit system comprising of a pair of spin-1/2 nuclei using Nuclear Magnetic Resonance techniques. The essent…
Viscous Self Interacting Dark Matter Cosmology For Small Redshift
Abhishek Atreya, Jitesh R. Bhatt, Arvind Kumar Mishra
The viscosity of dark matter in cosmological models may cause an accelerated expansion and when this effect is sufficiently large, it can explain the dark energy. In this work, att…
Clearing certain misconception in the common explanations of the aerodynamic lift
Navinder Singh, Navinder Singh Bathinda, K. Sasikumar Raja +1
Air travel has become one of the most common means of transportation. The most common question which is generally asked is: How does an airplane gain lift? And the most common answ…
Chiral symmetry breaking, color superconductivity, and the equation of state for magnetized strange quark matter
Aman Abhishek, Hiranmaya Mishra
We investigate the vacuum structure of dense quark matter in strong magnetic fields at finite temperature and densities in a 3 flavor Nambu Jona Lasinio (NJL) model including the K…
