Topological susceptibility with a single light quark flavour
Julien Frison, Ryuichiro Kitano, Norikazu Yamada
One of the historical suggestions to tackle the strong CP problem is to take the up quark mass to zero while keeping finite. The angle is then supposed to become irreleva…
in gauge theories
Ryuichiro Kitano, Takao Suyama, Norikazu Yamada
In gauge theory, it is argued recently that there exists a "mixed anomaly" between the CP symmetry and the 1-form symmetry at , and the anomaly matching…
High-energy Neutrinos from Multi-body Decaying Dark Matter
Nagisa Hiroshima, Ryuichiro Kitano, Kazunori Kohri +1
Since the report of the PeV-TeV neutrinos by the IceCube Collaboration, various particle physics models have been proposed to explain the neutrino spectrum by dark matter particles…
More on Electroweak-Skyrmion
Ryuichiro Kitano, Masafumi Kurachi
We discuss the properties of the topological soliton, or the Electroweak-Skyrmion, in the system of the Standard Model Higgs Lagrangian with addition of general O(p^4) terms. We sh…
