Topological obstructions to geometric positivity and negativity on Calabi-Yau manifolds
Ping Li
We study whether the topology underlying a Calabi-Yau manifold can support natural geometric positivity or negativity structures. In even complex dimension (assuming $b_…

Electroweak right-handed neutrino portal dark matter
Wan-Zhe Feng, Ao Li, Zong-Huan Ye +1
We study dark matter coupled to the Standard Model via electroweak scale right-handed neutrinos in a Type-I seesaw framework. We consider a minimal dark sector containing a fermion…
