Constraining the Coexistence of Primordial Black Holes and Particle Dark Matter with Neutrino Observations
Prolay Chanda, Sagnik Mukherjee, James Unwin
The paper studies how high‑energy neutrino data can limit scenarios where primordial black holes coexist with particle dark matter, focusing on enhanced annihilation in dark‑matter…
Minimal Freeze-in Dark Matter: Reviving electroweak doublet dark matter with Boltzmann suppressed freeze-in
Nicolás Bernal, Sagnik Mukherjee, James Unwin
Dark matter communicating with the Standard Model solely via electroweak interactions provides a compelling picture. However, thermal freeze-out of electroweak doublet dark matter…
VASR: Variance-Aware Systematic Resampling for Reward-Guided Diffusion
Shivanshu Shekhar, Sagnik Mukherjee, Jia Yi Zhang +1
Sequential Monte Carlo (SMC) samplers for reward-guided diffusion models often suffer from rapid lineage collapse: a few high-reward particles dominate the population within a hand…
Next-to-Minimal Freeze-in Dark Matter
Nicolás Bernal, Sagnik Mukherjee, James Unwin
If the dark matter mass exceeds the highest temperature of the thermal bath, then dark matter production is Boltzmann suppressed. This opens new possibilities for dark matter model…
Constraining the Coexistence of Freeze-in Dark Matter and Primordial Black Holes
Prolay Chanda, Sagnik Mukherjee, James Unwin
Particle dark matter and primordial black holes (PBH) might coexist with appreciable cosmic abundances, with both contributing to the observed dark matter density . La…
Boltzmann Suppressed Ultraviolet Freeze-in
Nicolás Bernal, Sagnik Mukherjee, James Unwin
If the dark matter mass exceeds the maximum temperature of the Universe (), then its production rate will be Boltzmann suppressed. The important implications o…
