Relations Between Standard Model Parameters from T ′ Flavor Symmetry
Spontaneously broken flavor symmetry involving the binary tetrahedral group T ′ relates parameters in the standard model. In one example the CP violating phase δPMNS and atmospheric mixing angle θ23 of neutrinos are related to the Cabibbo mixing angle ΘC for quarks. A second formula relates a ratio of neutrino mass eigenvalues to the Cabibbo angle. [email protected] [email protected]...
متن کاملRelations Between Standard Model Parameters from T ′ Flavor Symmetry Paul
The standard model of particle physics contains a large number (28) of independently adjustable parameters mostly related to masses and mixings of the quarks and leptons. We reveal a method to provide testable formulas which relate parameters between the quark and lepton sectors by using a spontaneously broken flavor symmetry involving the binary tetrahedral group T ′ . In one formula the CP vi...
متن کاملFlavor without Flavor Symmetry
Non-trivial patterns of quark and lepton masses and mixings can arise without there being any underlying flavor symmetry that distinguishes among the three families. Two realistic examples are given.
متن کاملApproximate Flavor Symmetry in Supersymmetric Model
We investigate the maximal approximate flavor symmetry in the framework of generic minimal supersymmetric standard model. We consider the low energy effective theory of the flavor physics with all the possible operators included. Spontaneous flavor symmetry breaking leads to the approximate flavor symmetry in Yukawa sector and the supersymmetry breaking sector. Fermion mass and mixing hierachie...
متن کاملFlavor Symmetry and Quark Model of Hadrons
As discussed in the previous Chapter, when the universe cools below TC , quarks and gluons are clustered to form color-singlet hadrons. When the temperature gets sufficiently low, the anti-baryon density becomes negligible, and the excess baryon number (or baryon chemical potential) decides the density of residual baryons. Because the proton and neutrons (together called nucleons) are the lowes...
