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…
Exotic quark effects on the Higgs sector of the USSM at the LHC
S. W. Ham, S. K. OH
The Higgs sector of the U(1)-extended supersymmetric model is studied with great detail. We calculate the masses of the Higgs bosons at the one-loop level. We also calculate at the…
