Direct CP violation in decays and supersymmetry
Teppei Kitahara, Ulrich Nierste, Paul Tremper
The quantities and measure the amount of direct and indirect CP violation in decays, respectively. Using the recent lattice results from the RBC and UK…
Protophobic Light Vector Boson as a Mediator to the Dark Sector
Teppei Kitahara, Yasuhiro Yamamoto
The observation of a protophobic 16.7 MeV vector boson has been reported by a Be nuclear transition experiment. Such a new particle could mediate between the Standard Model and…
Singularity-free Next-to-leading Order Renormalization Group Evolution and in the Standard Model and Beyond
Teppei Kitahara, Ulrich Nierste, Paul Tremper
The standard analytic solution of the renormalization group (RG) evolution for the Wilson coefficients involves several singularities, which complicate analytic solutions.…
Towards a Scale Free Electroweak Baryogenesis
Kazuya Ishikawa, Teppei Kitahara, Masahiro Takimoto
We propose a new electroweak baryogenesis scenario in high-scale supersymmetric (SUSY) models. We consider a singlet extension of the minimal SUSY standard model introducing additi…
Singlino Resonant Dark Matter and 125 GeV Higgs Boson in High-Scale Supersymmetry
Kazuya Ishikawa, Teppei Kitahara, Masahiro Takimoto
We consider a singlino Dark Matter (DM) scenario in a singlet extension model of the Minimal Supersymmetric Standard Model, which is so-called the Nearly MSSM (nMSSM). We find that…
