Analysis of quark mixing using binary tetrahedral flavor symmetry

Abstract

Using the binary tetrahedral group T ′ , the three angles and phase of the quark CKM mixing matrix are pursued by symmetry-breaking which involves T ′ -doublet VEVs and the Chen-Mahanthappa CPviolation mechanism. The NMRT ′ M, Next-to-Minimal-Renormalizable -T ′ -Model is described, and its one parameter comparison to experimental data is explored.

S4as a natural flavor symmetry for lepton mixing

“…Lot of theoretical models has been done to explain the mixing matrix of eq. (1) by means of non abelian flavor symmetry, such as S 3 [3,4,5,6,7,8,9,10,11,12,13], A 4 [14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29], T ′ [30,31,32,33,34], S 4 [35,36,37,38,39] and ∆ (27) [40,41,42,43]. The non abelian discrete groups have irreducible representations of dimension bigger than one [44].…”

Neutrino Oscillations in the de Sitter and the Anti-de Sitter Space-Time

“…Lambiase studied pulsar kicks induced by spin flavor oscillations of neutrinos [26], the neutrino geometrical optics in gravitational field [27] and the neutrino mass spectrum [28]. Some publications were focused on the theoretical study and experimental measurement of the mixing angle θ 13 [29][30][31]. And CP violation in neutrino oscillations were considered by some authors [32][33][34][35][36].…”

Neutrino Oscillations in the Robertson-Walker Metric and the Cosmological Blue Shift of the Oscillation Length

“…A further mechanism to generate pulsar kicks, which was based on the spin flavor conversion of neutrinos propagating in a gravitational field, and the neutrino geometrical optics in gravitational field (in particular in a Lense-Thirring background), have been proposed by Lambiase [27,28]. Some publications were centered on the theoretical study and experimental measurement of the mixing angle θ 13 [29][30][31]. And CP violation in neutrino oscillations were considered by some authors [32][33][34][35].…”
