Towards an effective field theory on the light-shell

So, classically, in the very high energy limit, everything lies on an expanding sphere at t = r, which we call the light-shell. It is worth m ...

Different observers will observe particles in different ways. The only way one could reconcile this with common sense was to acc ...

A New Constraint on Strongly Coupled Field Theories

Under these circumstances we see that f is a constant, and fIR is equal to fU V . Of course the theories that we are interested in are not ...

Effective field theory methods applied to the 2-body

The existence of gravitational waves (GW) is an unavoidable prediction of General Relativity (GR): any change to a gravitating source must be communicated to distant observers no faster than the speed of light, c, leading to the existence of gravitational radiation, or GWs.

Quantum Field Theory in Curved Spacetime and Horizon
... In sections 1 and 2 we discuss how a large class of metrics with horizons can be approximated locally as a Rindler horizon. In section 3, we discuss Lanczos-Lovelock gravity and some results related to them. Much of the discussion in sections 1 and 2 is based on [3] and section 3 is based on [1]. ...
