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…
The 3.5 keV Line from Stringy Axions
Michele Cicoli, Victor A. Diaz, Veronica Guidetti +1
An interesting result in particle astrophysics is the recent detection of an unexplained 3.5 keV line from galaxy clusters. A promising model, which can explain the morphology of t…
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…
