Theoretical and Phenomenological Status of Neutrino Physics: A Brief Review
No full textWe present an overview of recent progress in the theoretical and phenomenological studies of neutrino masses, lepton avor mixing, and CP violation. Firstly, We discuss the status of neutrino mass with in the Standard Model (SM) of particle physics. Then the possible ways in which neutrino mass terms can be included in the SM are discussed. The inclusion of new physics beyond the SM inevitably brings new parameters which are not constrained by the present
experimental data on neutrino masses and mixing angles and, thus, are free parameters of the theory. We, also, discuss various theoretically motivated phenomenological approaches which can be used to reduce the number of free parameters and, thus, provide an excellent tool to understand the underlying physics of neutrino masses and mixings. Current experimental constraints on
the neutrino mass spectrum and the lepton avor mixing parameters, including the recent observation of nonzero θ13, have been summarized. Finally, We discuss the renewed interest in the possible existence of one or more sterile
neutrinos and their phenomenology
Implications of Non-unitarity on , Neutrino Mass Hierarchy and CP-Violation Discovery Reach in Neutrino Oscillation Experiments
No full textLEPTOGENESIS IN A HYBRID TEXTURE NEUTRINO MASS MODEL
No full text We investigate the CP asymmetry for a hybrid texture of the neutrino mass matrix predicted by Q8 family symmetry in the context of the type-I seesaw mechanism and examine its consequences for leptogenesis. We, also, calculate the resulting Baryon Asymmetry of the Universe (BAU) for this texture. </jats:p
Prospects for reconstruction of leptonic unitarity quadrangle and neutrino oscillation experiments
No full textAbstractAfter the observation of non-zero θ13 the goal has shifted to observe CP violation in the leptonic sector. Neutrino oscillation experiments can, directly, probe the Dirac CP phases. Alternatively, one can measure CP violation in the leptonic sector using Leptonic Unitarity Quadrangle (LUQ). The existence of Standard Model (SM) gauge singlets – sterile neutrinos – will provide additional sources of CP violation. We investigate the connection between neutrino survival probability and rephasing invariants of the 4×4 neutrino mixing matrix. In general, LUQ contain eight geometrical parameters out of which five are independent. We obtain CP asymmetry (Pνf→νf′−Pν¯f→ν¯f′) in terms of these independent parameters of the LUQ and search for the possibilities of extracting information on these independent geometrical parameters in short baseline (SBL) and long baseline (LBL) experiments, thus, looking for constructing LUQ and possible measurement of CP violation. We find that it is not possible to construct LUQ using data from LBL experiments because CP asymmetry is sensitive to only three of the five independent parameters of LUQ. However, for SBL experiments, CP asymmetry is found to be sensitive to all five independent parameters making it possible to construct LUQ and measure CP violation
Nonstandard Interactions and Prospects for Studying Standard Parameter Degeneracies in DUNE and T2HKK
No full textThe future long baseline experiments such as DUNE and T2HKK have promising prospects to determine the neutrino mass hierarchy and measuring standard CP phase δ. However, presence of possible nonstandard interactions of neutrinos with matter may intricate this picture and is the subject matter of the present work. We have studied the standard parameter degeneracies in presence of nonstandard interactions (NSI) with DUNE and T2HKK experiments. We examine the mass hierarchy degeneracy assuming (i) all NSI parameters to be nonzero and (ii) one NSI parameter (ϵeμ) and its corresponding CP phase (δeμ) to be nonzero. We find that the latter case is more appropriate to resolve mass hierarchy degeneracy with DUNE and T2HKK experiments due to relatively small uncertainties emanating from the NSI sector. We have, also, investigated the octant degeneracy with neutrino (νμ→νe) and antineutrino (ν¯μ→ν¯e) mode separately. We find that to resolve this degeneracy the long baseline experiment with combination of neutrino and antineutrino mode is essential. Furthermore, we have considered DUNE in conjunction with T2HKK experiment to study CP phase degeneracy due to standard (δ) and nonstandard (δeμ) CP phases. We find that DUNE and T2HKK, in conjunction, have more sensitivity for CP violation effects (10σ for true NH and 8.2σ for true IH)

Drying Kinetics and Modelling of Mass Transfer in Thin Layer Convective Drying of Pineapple
No full textThe aim of the investigation was to study the drying characteristics of pineapple at different
temperatures of 55, 60, 65, 70 and 75°C with 1.5 m/ s constant air velocity. In the present study, the
best drying model was selected to describe the drying behaviour, and to develop the moisture
profile using COMSOL. Based on the best criteria, Verma et al. was chosen as the best fit to the
experimental data. The predicted moisture ratio values obtained from COMSOL simulation and
Verma et al. were good agreement with the experimental data
