Chiral Anomaly and Schwinger Effect in Non-Abelian Gauge Theories
Valerie Domcke, Yohei Ema, Kyohei Mukaida +1
We study the production of chiral fermions in a background of a strong non-abelian gauge field with a non-vanishing Chern-Pontryagin density. We discuss both pair production analog…
Light Dark Matter at Neutrino Experiments
Yohei Ema, Filippo Sala, Ryosuke Sato
Sub-GeV Dark Matter particles upscattered by cosmic rays gain enough kinetic energy to pass the thresholds of large volume detectors on Earth. We then use public Super-Kamiokande a…
Probing Electroweakly Interacting Massive Particles with Drell-Yan Process at 100 TeV Hadron Colliders
So Chigusa, Yohei Ema, Takeo Moroi
There are many models beyond the standard model which include electroweakly interacting massive particles (EWIMPs), often in the context of the dark matter. In this paper, we study…
Unitarity constraint on the Kähler curvature
Yohei Ema, Ryuichiro Kitano, Takahiro Terada
In supersymmetric theories, the signs of quartic terms in the Kähler potential control the stability of non-supersymmetric field configurations. In particular, in supersymmetric in…
Production of Purely Gravitational Dark Matter
Yohei Ema, Kazunori Nakayama, Yong Tang
In the purely gravitational dark matter scenario, the dark matter particle does not have any interaction except for gravitational one. We study the gravitational particle productio…
Supersymmetric Flaxion
Yohei Ema, Daisuke Hagihara, Koichi Hamaguchi +2
Recently, a new minimal extension of the Standard Model has been proposed, where a spontaneously broken, flavor-dependent global U(1) symmetry is introduced. It not only explains t…
