Abstract There is no reason why the gauge symmetry extension is family universal as in the standard model and the most well-motivated models, e.g. left-right symmetry and grand unification. Hence, we propose a simplest extension of the standard model

Abstract The $$SU(3)_L\otimes U(1)_X$$ S U ( 3 ) L ⊗ U ( 1 ) X symmetry actually studied is directly broken to the electroweak symmetry $$SU(2)_L\otimes U(1)_Y$$ S U ( 2 ) L ⊗ U ( 1 ) Y by a Higgs triplet, predicting a relevant new physics at TeV

Abstract Quark has an electric charge either $$-1/3$$ - 1 / 3 or 2/3 and a baryon number 1/3, where the divisions 3’s match the color number. Although the electric charge and the baryon number have a nature distinct from the color charge, the match

Abstract The recent precision measurement of the W-boson mass reveals an exciting hint for the new physics as of the 3-3-1 model. We indicate that the 3-3-1 model contains distinct sources by itself that may cause the W-mass deviation, as measured, s

Since the electric charge in the standard model is theoretically not quantized, we may have a variant of it, called dark charge. Similar to the electric charge, the dark charge neither commutes nor closes algebraically with SU(2)L. The condition of a

Abstract We present the features of the fully flipped 3-3-1-1 model and show that this model leads to dark matter candidates naturally. We study two dark matter scenarios corresponding to the triplet fermion and singlet scalar candidates, and we dete

Abstract It is shown that for a higher weak isospin symmetry, SU(P) L with P ≥ 3, the baryon minus lepton charge B − L neither commutes nor closes algebraically with SU(P) L similar to the electric charge Q, which all lead to a SU(3) C ⊗ SU(P)

Abstract The present matter content of our universe may be governed by a $$U(1)_{B-L}$$ U ( 1 ) B - L symmetry – the simplest gauge completion of the seesaw mechanism which produces small neutrino masses. The matter parity results as a residual gau

Abstract We argue that neutrino mass and dark matter can arise from an approximate B − L symmetry. This idea can be realized in a minimal setup of the flipped 3-3-1 model, which discriminates lepton families while keeping universal quark families a

Abstract It is well established that the SU(P)L gauge symmetry for P ≥ 3 can address the question of fermion generation number due to the anomaly cancellation, but it neither commutes nor closes algebraically with electric and baryon-minus-lepton c
