Resonant conversion of axion dark radiation into terahertz electromagnetic radiation in a neutron star magnetosphere
Andrew J. Long, Enrico D. Schiappacasse
In the strong magnetic field of a neutron star's magnetosphere, axions coupled to electromagnetism develop a nonzero probability to convert into photons. Past studies have revealed…
Cosmological gravitational particle production of massive spin-2 particles
Edward W. Kolb, Siyang Ling, Andrew J. Long +1
The phenomenon of cosmological gravitational particle production (CGPP) is expected to occur during the period of inflation and the transition into a hot big bang cosmology. Partic…
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…
Evolution of the Baryon Asymmetry through the Electroweak Crossover in the Presence of a Helical Magnetic Field
Kohei Kamada, Andrew J. Long
We elaborate upon the model of baryogenesis from decaying magnetic helicity by focusing on the evolution of the baryon number and magnetic field through the Standard Model electrow…
