Resolving the Ultracollinear Paradox with Effective Field Theory
Matthew Baumgart, Panagiotis Christeas
Naive intuition about scale decoupling breaks down in the presence of fermion masses. Kinematic enhancements can greatly extend the range where one needs to keep a finite mass in c…

Manifestly Unitary Cosmological Perturbation Theory
Panagiotis Christeas, Logan Thomas
The next decade will feature an abundance of novel cosmological data, while many fundamental questions about inflation remain. Given this, there is ample need for maximally efficie…
