Higgs boson masses in an extension of the MSSM with vector-like quarks
S. W. Ham, Seong-A Shim, C. M. Kim +1
We study the Higgs sector of the minimal supersymmetric standard model extended with vector-like quarks, at the one-loop level. The radiative corrections to the tree-level masses o…
Electroweak phase transition in an extension of the Standard Model with scalar color octet
S. W. Ham, Seong-a Shim, S. K. Oh
In an extension of the Standard Model with a scalar color octet, the possibility of the strongly first-order electroweak phase transition is studied, by examining the finite-temper…
Electroweak baryogenesis in the MSSM with vector-like quarks
S. W. Ham, Seong-A Shim, S. K. Oh
In the minimal supersymmetric standard model (MSSM), a strongly first-order electroweak phase transition (EWPT) is only possible in a confined parameter region where one of the sca…
Study of Higgs self couplings of a supersymmetric model at the International Linear Collider
S. W. Ham, Kideok Han, Jungil Lee +1
We study the Higgs self couplings of a supersymmetric model that has two Higgs doublets and two Higgs singlets. The lightest scalar Higgs boson in the model may be heavier th…
Explicit CP violation in the Dine-Seiberg-Thomas model
S. W. Ham, Seong-a Shim, S. K. OH
The possibility of explicit CP violation is studied in a supersymmetric model proposed by Dine, Seiberg, and Thomas, with two effective dimension-five operators. The explicit CP vi…
Possibility of spontaneous CP violation in Higgs physics beyond the minimal supersymmetric standard model
S. W. Ham, Seong-a Shim, S. K. OH
The Dine-Seiberg-Thomas model (DSTM) is the simplest version of the new physics beyond the minimal supersymmetric standard model (MSSM), in the sense that its Higgs sector has just…
