Effective Field Theory of Stückelberg Vector Bosons
Graham D. Kribs, Gabriel Lee, Adam Martin
We explore the effective field theory of a vector field that has a Stückelberg mass. The absence of a gauge symmetry for implies Lorentz-invariant operators are cons…

Effective Field Theory Perspective On King Non-linearity
Benoît Assi, Benoît Assi, Sam Carey +6
Precision spectroscopic measurements of isotope shifts have recently reached a high level of accuracy. Tests of King non-linearity (NL) along isotope chains have been proposed as a…
