Transverse spherocity is an event shape observable which is capable of separating pQCD-dominated jetty events from soft QCD-dominated isotropic events. Recent studies show that transverse spherocity can be applied not only in pp collisions but in heavy-ion collisions, which are relatively dominated by soft-QCD processes. We take this scope of transverse spherocity to exploit its use to probe...

The expansion rate of the Universe is modified when the total energy density receives a substantial contribution from a new scalar field, along with the standard radiation energy. This results in a few crucial changes in the set of Boltzmann equations for leptogenesis, governing the evolution of abundance of decaying particle and the lepton asymmetry. Thus the analytical solution of Boltzmann...

We use the optimal observable technique to determine the statistical accuracy to which the coupling of such fermions to the Z gauge boson (vector, axial or chiral) can be measured in case of signal-only hypothesis as well as in presence of non-interfering SM background.

A core-collapse supernova explosion releases 99\% of the progenitor star's gravitational energy in the form of neutrinos resulting in emission of a huge number of MeV neutrinos ($\sim \mathcal{O}(10^{56})$). This neutrino emission takes place in three different phases, namely the {\it neutronisation burst, accretion and cooling} pertaining to different physical processes. Interestingly,...

The phenomena of neutrino oscillation is an excellent platform to study new-physics beyond the Standard Model, popularly known as BSM. The unknown couplings involving neutrinos, termed non-standard interactions (NSI), may appear as `new-physics' in different neutrino experiments. The neutrino NSIs may have significant effects on neutrino oscillations and CP-sensitivity, which may be studied in...

To cope with severe radiation dosage and increased event pileup in a high luminosity environment, the existing endcap calorimeters of the CMS experiment will be replaced by a high granularity calorimeter (HGCAL). To make the most of the increased granularity, a precise placement of detector modules into the sampling planes is of utmost importance. This requires the module components’ physical...

We study the quantisation of $\kappa$-deformed Dirac field by adopting a quantisation method that uses only equations of motion for quantising the field. Starting from $\kappa$-deformed Dirac equation, valid up to first order in the deformation parameter $a$, we derive deformed unequal time anti-commutation relation between deformed field and its adjoint, leading to an undeformed oscillator...

However, in this model 'ad-hoc' $Z_2$ symmetry is needed to explain the DM stability and it does not shed any light on the flavor structure of neutrino, that's why for the explanation of flavor structure of neutrino one has to add...

Cosmic rays interacting with air molecules produce cascades of particles which have hadronic, electromagnetic, and muonic components. Among these, muons can reach deep underground. These are used to study cosmic rays at different underground depths. As muons are mainly produced from the decay of pions and kaons, the muon rate depends on the probability of mesons to decaying versus...
