In this work, we have investigated the phenomenology of inverse neutrino mass matrix ((m_{nu }^{{ - 1}})) with one-zero textures considering neutrino mixing matrix to be of TM1 type. There are six possible patterns of (m_{nu }^{{ - 1}}) with one-zero. We have obtained the predictions for the least known neutrino sector parameters such as octant of atmospheric mixing angle, ({{theta }_{{23}}}), Dirac-type CP violating phase, δ, and effective Majorana neutrino mass, ({{m}_{{ee}}}). One of the generic feature of this class of model is the existence of necessary CP violation, i.e., Dirac CP phase δ is non-zero. For maximal value of ({{theta }_{{23}}} = 45^circ ), the model predicts maximal CP violation. The (0nu beta beta ) decay experiments have imperative consequences for viability of one-zero texture in (m_{nu }^{{ - 1}}). It will either refute a model completely or have distinguishing implications for neutrino mass ordering in a model. We have also proposed two possible scenarios in which such phenomenological conjecture may be realized using non-Abelian discrete flavor symmetry group ({{A}_{4}}) and cyclic group ({{Z}_{3}}).","PeriodicalId":730,"journal":{"name":"Physics of Particles and Nuclei Letters","volume":"21 6","pages":"1124 - 1138"},"PeriodicalIF":0.4,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142679791","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such term—in other works—has been accounted for nonlocality due to the surface deformation in the light nuclei. In the present work, we have examined the ability of the velocity-dependent potential, which contains real surface-peaked terms, to account for nonlocality. This is achieved by inspecting the case of fitting the angular distribution data for the neutron that elastically scattered from a light nucleus, carbon isotopes (10C, 12C, and 14C) in the energy range of 12–20 MeV, by using two potential models: the modified velocity optical potential (which conations real surface-term) and the conventional optical potential. A comparison between the two models has been made. Furthermore, the total elastic cross sections and the analyzing power are calculated using both models and compared to the experimental data. The volume integrals per nucleon of the real central potential and the imaginary surface potential in the modified velocity optical potential have also been determined and the results are in good agreement with the corresponding values calculated using other models. It is shown that a significant improvement in angular distributions was observed when the velocity-dependent potential was applied, specifically in the large angle scattering region and in certain energy ranges.","PeriodicalId":730,"journal":{"name":"Physics of Particles and Nuclei Letters","volume":"21 6","pages":"1190 - 1207"},"PeriodicalIF":0.4,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142679499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
