FXGAR Mass Matrices: A Unique Viable Set for Quarks and Leptons

FXGAR mass matrices (to be defined later) are a particular class of texture 4 zero hermitian mass matrices, known to be quite successful in explaining the quark mixing data. Following the spirit of quark lepton symmetry as well as assuming neutrinos to be Dirac particles, an attempt has been made to examine the viability of FXGAR mass matrices for the lepton sector. Our analysis reveals that Inverted Ordering (IO) of neutrino masses is ruled out while Normal Ordering (NO) continues to be viable.
