TeV-scale vector leptoquark from Pati-Salam unification with vectorlike families
Syuhei Iguro, Junichiro Kawamura, Shohei Okawa +1
In this paper, we show an explicit way to realize a TeV-scale vector leptoquark from the Pati-Salam (PS) unification with extra vectorlike families. The leptoquark mass is constrai…
Search for U(1) charged Dark Matter with neutrino telescope
Kento Asai, Shohei Okawa, Koji Tsumura
We study a simple Dirac fermion dark matter model in U(1) theory. The new light gauge boson plays important roles in both dark matter physics and the explanation fo…
Current status and muon explanation of lepton portal dark matter
Junichiro Kawamura, Shohei Okawa, Yuji Omura
In this paper, we summarize phenomenology in lepton portal dark matter (DM) models, where DM couples to leptons and extra leptons/sleptons. There are several possible setups: compl…
Electric Dipole Moments From Dark Sectors
Shohei Okawa, Maxim Pospelov, Adam Ritz
We examine the sensitivity of electric dipole moments (EDMs) to new -violating physics in a hidden (or dark) sector, neutral under the Standard Model (SM) gauge groups, and cou…
WIMP dark matter in the parity solution to the strong CP problem
Junichiro Kawamura, Shohei Okawa, Yuji Omura +1
We extend the Standard Model (SM) with parity symmetry, motivated by the strong CP problem and dark matter. In our model, parity symmetry is conserved at high energy by introducing…
Impact of the anomalies on dark matter physics
Junichiro Kawamura, Shohei Okawa, Yuji Omura
Recently, the LHCb collaboration has reported the excesses in the processes. One of the promising candidates for new physics to explain the anomalies is the extended S…
