Dark Matter emission at Belle II and NA62 in Minimal Flavor Violation framework
Federico Mescia, Shohei Okawa, Joel Swallow +1
Minimal Flavor Violation (MFV) provides a compelling framework for exploring physics beyond the Standard Model, in which new QCD-singlet fields transforming under the global $\math…
Novel bounds on neutrino portal dark matter from leptonic meson decays
Shohei Okawa, Yuji Omura
We investigate the potential of leptonic meson decays , where is a pseudo-scalar meson, as a probe of neutrino portal dark matter. The model of our focu…
Dirac neutrino and dark matter in left-right symmetric models
Shohei Okawa, Yuji Omura, Keyun Wu
We study neutrino mass generation and dark matter in a left-right symmetric model. The model is based on an gauge theory wi…
New Constraints on Gauged U(1) Models via Mixing
Kento Asai, Coh Miyao, Shohei Okawa +1
It is known that the model based on U(1) gauge symmetry can explain not only the discrepancy between the measured value of muon and the theoretical prediction,…
Multi-Component Dark Matter from Minimal Flavor Violation
Federico Mescia, Shohei Okawa, Keyun Wu
Minimal Flavor Violation (MFV) offers an appealing framework for exploring physics beyond the Standard Model. Interestingly, within the MFV framework, a new colorless field that tr…
