dc.description.abstractSeesaw mechanism is a popular approach to give a viable explanation to the source of non-zero neutrino mass and to the cause of matter dominance of the Universe - two of the most important open problems that could not be answered in the Standard Model (SM) of Particle Physics. A minimal extension of the SM is studied, incorporating type-I+II seesaw mechanism with only one right-handed neutrino and one Higgs triplet scalar. Both of these heavy particles contribute to the generation of tiny neutrino mass, the contribution being inversely proportional to the corresponding heavy particle masses.Considering the leptogenesis is being achieved by the decay of the right-handed neutrino, the new source of CP violation is getting generated solely from the decay of the right-handed neutrino by one-loop vertex correction in the presence of the Higgs triplet scalar. The predictability of the model is further enhanced by introducing Fritzsch type 2-zero and 3-zero textures for the neutrino mass matrix and the non-diagonal charged lepton mass matrix, respectively. The parameter space study is executed following the latest neutrino oscillation parameter data and the phenomenological importance of thishybrid texture is analysed. Leptogenesis is successfully achieved in flavoured regime within the temperature range T ⊂ [1010, 1012] GeV.en_US
