Nuclear Predictions for Spectroscopy without Nuclear Errors
C. P. Burgess, P. Hayman, Markus Rummel +1
Nuclear-structure effects often provide an irreducible theory error that prevents using precision atomic measurements to test fundamental theory. We apply newly developed effective…
Precision Nuclear-Spin Effects in Atoms: EFT Methods for Reducing Theory Errors
L. Zalavari, C. P. Burgess, P. Hayman +1
We use effective field theory to compute the influence of nuclear structure on precision calculations of atomic energy levels. As usual, the EFT's effective couplings correspond to…
Point-Particle Catalysis
P. Hayman, C. P. Burgess
We use the point-particle effective field theory (PPEFT) framework to describe particle-conversion mediated by a flavour-changing coupling to a point-particle. We do this for a toy…
Reduced Theoretical Error for QED Tests with 4He+ Spectroscopy
C. P. Burgess, P. Hayman, Markus Rummel +1
We apply point-particle effective field theory (PPEFT) to electronic and muonic 4He+ ions, and use it to identify linear combinations of spectroscopic measurements for which the th…
Point-Particle Effective Field Theory III: Relativistic Fermions and the Dirac Equation
C. P. Burgess, Peter Hayman, Markus Rummel +1
We formulate point-particle effective field theory (PPEFT) for relativistic spin-half fermions interacting with a massive, charged finite-sized source using a first-quantized effec…
The Proton Radius Problem and Point-Particle Effective Field Theory
C. P. Burgess, Peter Hayman, Markus Rummel +1
We argue that the proton's charge-radius contributes differently to shifts of Hydrogen-like energy levels than naively expected due to an incorrect choice for the boundary conditio…
A Time Projection Chamber with GEM-Based Readout
The LCTPC Collaboration, David Attié, Ties Behnke +67
For the International Large Detector concept at the planned International Linear Collider, the use of time projection chambers (TPC) with micro-pattern gas detector readout as the…
Magnon Inflation: Slow Roll with Steep Potentials
Peter Adshead, Diego Blas, C. P. Burgess +2
We find multi-scalar effective field theories (EFTs) that can achieve a slow inflationary roll despite having a scalar potential that does not satisfy the usual slow-roll condition…
