Fifth forces and broken scale symmetries in the Jordan frame
Edmund J. Copeland, Peter Millington, Sergio Sevillano Muñoz
We study the origin of fifth forces in scalar-tensor theories of gravity in the so-called Jordan frame, where the modifications to the gravitational sector are manifest. We focus o…
Non-Hermiticity: a new paradigm for model building in particle physics
Peter Millington
Non-Hermitian quantum theories have been applied in many other areas of physics. In this note, I will briefly review recent developments in the formulation of non-Hermitian quantum…
EuCAPT White Paper: Opportunities and Challenges for Theoretical Astroparticle Physics in the Next Decade
R. Alves Batista, M. A. Amin, G. Barenboim +134
Astroparticle physics is undergoing a profound transformation, due to a series of extraordinary new results, such as the discovery of high-energy cosmic neutrinos with IceCube, the…
IR/UV mixing from local similarity maps of scalar non-Hermitian field theories
Maxim N. Chernodub, Peter Millington
We propose to "gauge" the group of similarity transformations that acts on a space of non-Hermitian scalar theories. We introduce the "similarity gauge field", which acts as a gaug…
Benchmarking regulator-sourced 2PI and average 1PI flow equations in zero dimensions
Peter Millington, Paul M. Saffin
We elucidate the regulator-sourced 2PI and average 1PI approaches for deriving exact flow equations in the case of a zero dimensional quantum field theory, wherein the scale depend…
Fifth-Force Screening around Extremely Compact Sources
Clare Burrage, Benjamin Elder, Peter Millington +2
Many non-linear scalar field theories possess a screening mechanism that can suppress any associated fifth force in dense environments. As a result, these theories can evade local…
