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…

An analytic study of the tricritical line in the U(Nf)xU(Nf) sigma model
Junichiro Yasuda
The tricritical line of the first-order chiral phase transition is investigated in the U(Nf)xU(Nf) sigma model by means of the ring improved one-loop finite temperature effective p…

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…
