Abstract We show how effects of compositeness emerging in a Composite 2-Higgs Doublet Model can enter Standard Model (SM)-like Higgs boson pair production at the Large Hadron Collider in both resonant and non-resonant mode. Such effects can arise fro

Abstract The Higgs portal interaction to a singlet sector of the standard model (SM) gauge group is widely-studied. In this paper, we show that a quantum effect is important if the Higgs field mixes with another singlet scalar field whose decay rate

Abstract We study phenomenological implications of an axion that arises as a pseudo Nambu-Goldstone boson due to the spontaneous breaking of anomaly-free global flavor symmetry. One interesting possibility for such anomaly-free axion to explain dark

Abstract Axion or axion-like particle (ALP) has been usually considered as a CP-odd Nambu-Goldstone boson (NGB) from the spontaneous breakdown of a global U(1) symmetry. In this paper, we point out that the NGB behaves as a CP-even particle coupled t

We calculate radiative corrections to decay rates of CP-odd Higgs boson A for various decay modes in the four types of two Higgs doublet models with the softly broken discrete Z2 symmetry. The decay branching ratios are evaluated at the next-to-leadi

Abstract The Higgs invisible decay width may soon become a powerful tool to probe extensions of the Standard Model with dark matter candidates at the Large Hadron Collider. In this work, we calculate the next-to-leading order (NLO) electroweak correc

Recently, the CDF collaboration has reported the precise measurement of the W boson mass, MW=80433.5±9.4MeV, based on 8.8 fb−1 of s=1.96 TeV pp¯ collision data from the CDF II detector at the Fermilab Tevatron. This is about 7σ away from the Sta

Abstract We evaluate the full next-to-leading order supersymmetric (SUSY) electroweak and SUSY-QCD corrections to the on-shell two-body decays of the charged Higgs bosons in the framework of the next-to-minimal supersymmetric extension of the Standar
