We propose a fermionic dark matter model by extending Standard Model with a Dirac fermion and a real pseudoscalar. The fermion dark matter particle interacts with the Standard Model sector via the Higgs portal through a dimension five interaction term as also through a pseudoscalar interaction term. The parameter space of the model is then constrained by using the vacuum stability and...

87. Non-equilibrium statistical mechanics, Fermion dark matter and SN1987A cooling

Dr PRASANTA DAS (B)

Light dark matter(1 − 30 MeV) particles which can be pair
produced in electron-positron annihilation e − e + → χ χ inside the
supernova SN1987A core, take away the energy released in the supernova
SN1987A explosion. Working within the framework of q-deformed scenario
(non-equilibrium statistics) and using the Raffelt’s criteria on the
energy loss rate and the optical depth criteria on the...

31. Confinement and de-confinement aspects of fermion in lower dimensional field theoretical model and its symmetry, e.g. BRST and field dependent BRST

Dr Anisur Rahaman (Hooghly Mohsin College)

Lower dimensional field theoretical models, e.g. Schwinger model, Chiral Schwinger model, Non-Confining Schwinger model, Thirring-Wess model and its Chiral generation known as Chiral Thirring-Wess model are of great interest because the models can explain the mass generation via dynamical symmetry breaking. It was known that the Schwinger can explain the confinement of fermions. However, in...

21. Signatures of parton saturation at small-x

Dr mayuri devee (University of Science and Technology, Meghalaya)

The parton saturation behaviour at small-x is shown in a semi-analytical solution of the nonlinear GLR-MQ equation with parton recombination corrections, which resembles the widely discussed BK saturation of gluons. The effect of gluon shadowing on the small-x and moderate-Q^2 behaviour of gluon and singlet quark distribution function is examined. The computed results are compared with...

62. Study of QCD Using Event Shape Variables in pp Collisions at /s = 13TeV

Corresponding author: skundu91phys@gmail.com

Quantum Chrmodynamics is an important subject of study at the colliding beam experiments. Event-Shape Variables (ESVs) are functions of the four-momenta of particles in hadronic final states and are theoretically robust. They are sensitive to both perturbative and non-perturbative aspects of QCD and help us understand the flow of energy in an...
