# Bottom quark and tau lepton masses in a toy ${\rm SU}(6)$

@inproceedings{Chen2021BottomQA, title={Bottom quark and tau lepton masses in a toy \$\{\rm SU\}(6)\$}, author={Ning Chen and Yingdong Mao and Zhaolong Teng}, year={2021} }

We study a toy SU(6) model with the symmetry breaking pattern of the extended 331 symmetry of SU(3) c ⊗ SU(3) W ⊗ U(1) X . A “fermion-Higgs mismatching” symmetry breaking pattern is proposed for more realistic model building. Within such symmetry breaking pattern, only one Higgs doublet develops vacuum expectation value for the spontaneous electroweak symmetry breaking, and gives tree-level top quark mass. A natural VEV splittings in the 331 breaking Higgs ﬁelds gives tree-level masses to both…

We study fermion masses and mixing angles, including the generation of a seesaw mechanism for the neutrinos, in extended technicolor (ETC) theories. We formulate an approach to these problems that…

Assuming that the leptons and quarks other than top are massless at tree level, we show that their masses may be induced by loops involving the top quark. As a result, the generic features of the…

The main contribution to this result is from processes in which Higgs bosons are produced in association with a W or Z boson (VH), and are searched for in final states including 0, 1, or 2 charged leptons and two identified bottom quark jets.

We show that there is an infinite number of U(1) symmetries like Peccei-Quinn symmetry in the 3-3-1 model with minimal scalar sector---two scalar triplets. Moreover, all of them are completely broken…
