Most of the free parameters in the Standard Model (SM)—a quantum field theory which has
successfully elucidated the behaviors of strong, weak and electromagnetic interactions of all …

We discuss the quark mass matrices in the A 4 modular symmetry, where the A 4 triplet of
Higgs is introduced for each up-quark and down-quark sectors, respectively. The model has …

A bstract An attractive feature of New Physics models with multiple Higgs fields is that they
are equipped with discrete symmetry groups in the Higgs and flavour sectors. These …

We propose a renormalizable multi-Higgs model with A 4⊗ Z 2⊗ Z 2′ symmetry accounting
for the experimental deviation from the tribimaximal mixing pattern of the neutrino mixing …

A bstract Multi-Higgs models equipped with global symmetry groups, either exact or softly
broken, offer a rich framework for constructions beyond the Standard Model and lead to …

A flavor-dependent model (FDM) is proposed in this work. The model extends the Standard
Model by an extra U (1) F local gauge group, two scalar doublets, one scalar singlet and two …

Abstract We propose a 3-3-1 model where the SU (3) _ C ⊗ SU (3) _ L ⊗ U (1) _ X SU (3)
C⊗ SU (3) L⊗ U (1) X symmetry is extended by S_ 3 ⊗ Z_ 3 ⊗ Z_ 3^ ′ ⊗ Z_ 8 ⊗ Z_ 16 S 3⊗ …

Abstract We construct a viable 3-3-1 model with two SU (3) _L SU (3) L scalar triplets,
extended fermion and scalar spectrum, based on the T^ ′ T′ family symmetry and other …

Abstract We build the first 3-3-1 model based on the Δ (27) discrete group symmetry,
consistent with fermion masses and mixings. In the model under consideration, the neutrino …

The LHC Higgs data are showing a gradual inclination towards the standard model (SM)
result, and realization of a SM-like limit becomes essential for beyond the SM scenarios to …
