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…
Supercool with PPO: Exploring Supercooled Phase Transitions via Reinforcement Learning
Wan-Zhe Feng, Zong-Huan Ye, Zi-Hui Zhang
Gravitational waves from cosmological first-order phase transitions provide a powerful probe of hidden sectors and beyond the Standard Model physics. However, identifying phenomeno…
Annihilating to the Darker: Thermal Relic Dark Matter with an Ultraweak Portal to the Standard Model
Wan-Zhe Feng, Zi-Hui Zhang
Thermal relic dark matter has been severely constrained in recent years by direct and indirect dark matter searches, as well as multi-messenger probes of dark sectors. At the curre…
Gauge-independent Gravitational Waves from Cogenesis in a Conserving Universe
Wan-Zhe Feng, Jinzheng Li, Pran Nath +1
An analysis of baryogenesis and stochastic gravitational wave production is presented for an extension of the standard model where the dark sector consists of dark matter particles…
Darker matter generating from the dark
Wan-Zhe Feng, Zi-Hui Zhang
The non-detection of dark matter may be attributed to the dark matter residing in a darker hidden sector. We explore the possibility that a hidden sector produced through the freez…
