SEAL - A Symmetry EncourAging Loss for High Energy Physics

Pradyun Hebbar, Thandikire Madula, Vinicius Mikuni +3

Physical symmetries provide a strong inductive bias for constructing functions to analyze data. In particular, this bias may improve robustness, data efficiency, and interpretabili…

Decoupled Weight Decay for Any Norm

Nadav Joseph Outmezguine, Noam Levi

With the success of deep neural networks (NNs) in a variety of domains, the computational and storage requirements for training and deploying large NNs have become a bottleneck for…

Probing New Physics at Cosmic Dawn with 21-cm Cosmology

Omer Zvi Katz, Nadav Outmezguine, Diego Redigolo +1

21-cm cosmology provides an exciting opportunity to probe new physics dynamics in the early universe. In particular, a tiny sub-component of dark matter that interacts strongly wit…

On the Late-Time Evolution of Velocity-Dependent Self-Interacting Dark Matter Halos

Sophia Gad-Nasr, Kimberly K. Boddy, Manoj Kaplinghat +2

We study the evolution of isolated self-interacting dark matter (SIDM) halos that undergo gravothermal collapse and are driven deep into the short-mean-free-path regime. We assume…

Anticipating a New-Physics Signal in Upcoming 21-cm Power Spectrum Observations

Rennan Barkana, Anastasia Fialkov, Hongwan Liu +1

Dark matter-baryon interactions can cool the baryonic fluid, which has been shown to modify the cosmological 21-cm global signal. We show that in a two-component dark sector with a…
