Peaky Production of Light Dark Photon Dark Matter
Yuichiro Nakai, Ryo Namba, Ippei Obata
We explore a mechanism to produce a light dark photon dark matter through a coupling between the dark photon field and a spectator scalar field which plays no role in the inflation…
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.…
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…
A Natural Model of Spontaneous CP Violation
Sudhakantha Girmohanta, Seung J. Lee, Yuichiro Nakai +1
We examine the possibility of building a natural non-supersymmetric model of spontaneous CP violation equipped with the Nelson-Barr (NB) mechanism to address the strong CP problem.…
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…
Deeply Learned Preselection of Higgs Dijet Decays at Future Lepton Colliders
So Chigusa, Shu Li, Yuichiro Nakai +3
Future electron-positron colliders will play a leading role in the precision measurement of Higgs boson couplings which is one of the central interests in particle physics. Aiming…
