“…Several systematic studies of textures zeros in the leptonic sector can be found in the literature; see, for instance, refs. Borgohain & Borah (2021), Cebola et al (2015), Ludl & Grimus (2014). In any search for experimentally viable texture‐zero structures for fermion mass matrices, it is important to take into account the freedom to make weak basis transformations, which do not change the physical content.…”

The existence of massive neutrinos is the first solid evidence of physics beyond the standard model of particle physics. A remarkable progress has been achieved in solar, atmospheric, reactor, and accelerator neutrino experiments during the last decades. On the theoretical side, several questions are being addressed, namely the Dirac or Majorana nature of neutrinos, the mechanisms for neutrino mass generation, and the relation between neutrinos and the matter–antimatter asymmetry observed in the Universe, among others. This article provides a brief overview on some of the current experimental and theoretical aspects in neutrino physics.

The magic textures are successful candidates of the correct texture for the Majorana neutrinos. In this study, we show that some types of magic texture for Majorana neutrinos approximately immanent in the flavor mass matrix for Dirac neutrinos. In addition, it turned out that the normal mass ordering of the Dirac neutrino masses is slightly preferable to the inverted mass ordering in the context of the magic textures.

“…The neutrino mass matrix carries the information of all the physical parameters mentioned above and the theorists in general, try to predict a promising neutrino mass matrix starting from the first principle. Several phenomenological ideas such as µ − τ symmetry [5][6][7], texture zeroes [8,9], hybrid textures [10,11], vanishing minors [12,13] etc. are attributed to the neutrino mass matrix and are studied extensively from both bottom-up and top-down viewpoints.…”
