The strongly coupled fourth family and a first-order electroweak phase transition (I) quark sector
Y. Kikukawa, M. Kohda, J. Yasuda
In models of dynamical electroweak symmetry breaking due to strongly coupled fourth-family quarks and leptons, their low-energy effective descriptions may involve multiple composit…

First-order restoration of SU(Nf) x SU(Nf) chiral symmetry with large Nf and Electroweak phase transition
Y. Kikukawa, M. Kohda, J. Yasuda
It has been argued by Pisarski and Wilczek that finite temperature restoration of the chiral symmetry SU(Nf) x SU(Nf) is first-order for Nf >=3. This type of chiral symmetry with a…

Nontriviality of Gauge-Higgs-Yukawa System and Renormalizability of Gauged NJL Model
M. Harada, Y. Kikukawa, T. Kugo +1
In the leading order of a modified 1/Nc expansion, we show that a class of gauge-Higgs-Yukawa systems in four dimensions give non-trivial and well-defined theories in the continuum…
