Electroweak phase transition, critical bubbles and sphaleron decoupling condition in the MSSM
Koichi Funakubo, Eibun Senaha
The electroweak phase transition and the sphaleron decoupling condition in the MSSM are revisited taking the latest experimental data into account. The light Higgs boson scenario a…
Sphalerons in the NMSSM
Koichi Funakubo, Akira Kakuto, Shuichiro Tao +1
We study sphaleron solutions in the next-to-minimal supersymmetric standard model. We find that the boundary condition on the singlet field at the origin of the radial coordinate i…
Phase Transitions in the NMSSM
Koichi Funakubo, Shuichiro Tao, Fumihiko Toyoda
We study phase transitions in the Next-to-Minimal Supersymmetric Standard Model (NMSSM) with the weak scale vacuum expectation values of the singlet scalar, constrained by Higgs sp…
The Higgs sector in the Next-to-MSSM
Koichi Funakubo, Shuichiro Tao
We study the Higgs sector in the Next-to-Minimal Supersymmetric Standard Model with and without explicit CP violation, focusing on the case of weak scale expectation value of the s…
CP Violation in the Higgs Sector and Phase Transition in the MSSM
K. Funakubo, S. Tao, F. Toyoda
We investigate the electroweak phase transition in the presence of a large CP violation in the squark sector of the MSSM. When the CP violation is large, scalar-pseudoscalar mixing…
Spontaneous CP Violation at Finite Temperature in the MSSM
K. Funakubo, A. Kakuto, S. Otsuki +1
By studying the effective potential of the MSSM at finite temperature, we find that CP can be spontaneously broken in the intermediate region between the symmetric and broken phase…
