Exploring Invisible Neutrino Decay at Long-Baseline Experiments Neutrino decay is one of the popular new physics scenario in neutrino sector. There are three active neutrinos and they can decay into lighter active neutrino state and boson(s), or it could decay into a sterile fermion and boson(s). In visible neutrinos decay, neutrinos decay into final active …

Impact of texture zeros of neutrino mass matrix on dark matter phenomenology We study an inverse seesaw ISS (2, 3) framework to explain neutrino phenomenology and dark matter simultaneously with one zero textures of neutrino mass matrix. ISS (2, 3) is obtained by the addition of two right handed neutrinos and three gauge singlets sterile …

Neutrinoless double beta decay in a flavor symmetric Scotogenic model We have studied the scotogenic model proposed by Ernest Ma, wherein the Standard Model is extended by three singlet right handed neutrinos and a scalar doublet. This model proposes that the light neutrinos acquire a non-zero mass at 1-loop level. We have done a A_4×Z_4 …

Realisation of Left right symmetric model by discrete flavor symmetries In this work, we have realised TeV scale Left-Right symmetric model (LRSM), where type I seesaw terms arises naturally using A_4×Z_2 discrete flavor symmetry. Within the model we have considered type I dominant cases to study neutrino phenomenology.Neutrinoless double beta decay is studied in the …

Improved potential approach and Masses of heavy flavour mesons In non-perturbative QCD potential models are extensively used to study several static and dynamic properties of heavy flavour mesons throughout the years with resonable phenomenological sucess. In this paper, we consider a new potential as reported recently by Hassanabadi etal., for QQ̄ system and applied quantum …

Surface Electron Microscope Based Morphological and Chemical Characterization of Atmospheric Aerosols Smoldering and Flaming combustion phases are very important combustion phases in biomass burning due to their different burning characteristics in respect to climate and health effects. In the present study, we have used scanning electron microscope (SEM) to characterize the surface morphology of the …
