Cosmological Phase Transitions in Composite Higgs Models
Kohei Fujikura, Yuichiro Nakai, Ryosuke Sato +1
We investigate cosmological phase transitions in various composite Higgs models consisting of four-dimensional asymptotically-free gauge field theories. Each model may lead to a co…
A Large Muon EDM from Dark Matter
Kim Siang Khaw, Yuichiro Nakai, Ryosuke Sato +2
We explore a model of dark matter (DM) that can explain the reported discrepancy in the muon anomalous magnetic moment and predict a large electric dipole moment (EDM) of the muon.…
ALP Dark Matter from Kinetic Fragmentation: Opening up the Parameter Window
Cem Eröncel, Ryosuke Sato, Geraldine Servant +1
The main mechanism responsible for Axion-Like-Particle (ALP) production in the early universe is the so-called misalignment mechanism. Three regimes have been investigated in this…
Muon Electric Dipole Moment as a Probe of Flavor-Diagonal CP Violation
Yuichiro Nakai, Ryosuke Sato, Yoshihiro Shigekami
Electric dipole moments (EDMs) of elementary particles are powerful probes of new physics with flavor-diagonal CP violation. The reported discrepancy in the muon anomalous magnetic…
Baryon Asymmetric Universe from Spontaneous CP Violation
Kohei Fujikura, Yuichiro Nakai, Ryosuke Sato +1
Spontaneous CP violation, such as the Nelson-Barr (NB) mechanism, is an attractive scenario for addressing the strong CP problem while realizing the observed phase of the Cabibbo-K…
Chiral Symmetry Breaking and Quark Bilinear Condensate in Large N QCD
Ryosuke Sato
We discuss spontaneous chiral symmetry breaking and quark bilinear condensate in large QCD. It has been known that the existence of meson is implied in large QCD a…
