Joint probes of dark matter annihilation from neutrino detectors and CMB targets

Ruifeng Leng, Shao-Ping Li

Dark matter (DM) annihilation into neutrinos provides a promising observational channel targeted by current and forthcoming neutrino detectors. However, the detection of such neutr…

Self-Interaction Bounds on Ultralight Dark Matter Couplings to Matter

Mohammad Aghaie, Shao-Ping Li

Ultralight dark matter (ULDM) couplings to matter fields and ULDM self-interactions are typically treated as independent probes. However, since the ULDM-matter couplings unavoidabl…

Dominant Thermal Resonant Mechanism for Low-Scale Leptogenesis

Shao-Ping Li, Apostolos Pilaftsis

We explicitly demonstrate the importance of a new thermal resonant channel in the context of low-scale leptogenesis, which goes beyond the well-known mixing and oscillation of mass…

The mass-coupling effect in leptogenesis

Shinya Kanemura, Shao-Ping Li

Particle decay in leptogenesis provides a simple avenue to explain the baryon asymmetric universe, where the decaying particle can provide the out-of-equilibrium condition to creat…

Bounds and detection of MeV-scale dark matter annihilation to neutrinos

Shinya Kanemura, Shao-Ping Li, Dibyendu Nanda

Current and most upcoming neutrino detectors can only reach a dark matter annihilation cross section to neutrinos larger than the standard freeze-out value, but they open intriguin…

Forbidden neutrinogenesis

Shinya Kanemura, Shao-Ping Li

The origin of neutrino masses can be simply attributed to a new scalar beyond the Standard Model. We demonstrate that leptogenesis can explain the baryon asymmetry of the universe…

Resonant Forbidden CP Asymmetry from Soft Leptons

Shinya Kanemura, Shao-Ping Li

To explain the baryon asymmetry in the early universe via leptogenesis, quantum corrections to new particles are commonly invoked to generate the necessary CP asymmetry. We demonst…

Observability of CMB spectrum distortions from dark matter annihilation

Shao-Ping Li

Even after dark matter chemically freezes out in the early universe, electromagnetic cascades from dark matter annihilation can still perturb the background photon spectrum when th…

A cosmological sandwiched window for lepton-number breaking scale

Shao-Ping Li, Bingrong Yu

A singlet majoron can arise from the seesaw framework as a pseudo-Goldstone boson when the heavy Majorana neutrinos acquire masses via the spontaneous breaking of global ${\rm U}(1…

Dark phase transition from WIMP: complementary tests from gravitational waves and colliders

Shinya Kanemura, Shao-Ping Li

A dark sector is an interesting place where a strong first-order phase transition, observable gravitational waves and/or a dark matter candidate could arise. However, the experimen…
