Completely Dark Matter from Rapid-Turn Multifield Inflation
Edward W. Kolb, Andrew J. Long, Evan McDonough +1
We study cosmological gravitational particle production as applied to "rapid-turn" models of inflation involving two scalar fields. We are interested in the production of massive s…
Snowmass Theory Frontier: Astrophysics and Cosmology
Daniel Green, Joshua T. Ruderman, Benjamin R. Safdi +84
We summarize progress made in theoretical astrophysics and cosmology over the past decade and areas of interest for the coming decade. This Report is prepared as the TF09 "Astrophy…
Quantum interference in gravitational particle production
Edward Basso, Daniel J. H. Chung, Edward W. Kolb +1
Previous numerical investigations of gravitational particle production during the coherent oscillation period of inflation displayed unexplained fluctuations in the spectral densit…
Searching for axion-like particles through CMB birefringence from string-wall networks
Mudit Jain, Ray Hagimoto, Andrew J. Long +1
Axion-like particles (ALPs) can form a network of cosmic strings and domain walls that survives after recombination and leads to anisotropic birefringence of the cosmic microwave b…
On Baryon and Lepton Number Violation
Pavel Fileviez Perez, Andrea Pocar, K. S. Babu +11
In this report we discuss the main theories to understand the origin of baryon and lepton number violation in physics beyond the Standard Model. We present the theoretical predicti…
An analytic evaluation of gravitational particle production of fermions via Stokes phenomenon
Soichiro Hashiba, Siyang Ling, Andrew J. Long
The phenomenon of gravitational particle production can take place for quantum fields in curved spacetime. The abundance and energy spectrum of gravitationally produced particles i…
