Three and Four Harmonically Trapped Particles in an Effective Field Theory Framework
J. Rotureau, I. Stetcu, B. R. Barrett +2
We study systems of few two-component fermions interacting via short-range interactions within a harmonic-oscillator trap. The dominant interactions, which are two-body, are organi…
The Nucleon Electric Dipole Form Factor From Dimension-Six Time-Reversal Violation
J. de Vries, E. Mereghetti, R. G. E. Timmermans +1
We calculate the electric dipole form factor of the nucleon that arises as a low-energy manifestation of time-reversal violation in quark-gluon interactions of effective dimension…
The Effective Chiral Lagrangian From the Theta Term
E. Mereghetti, W. H. Hockings, U. van Kolck
We construct the effective chiral Lagrangian involving hadronic and electromagnetic interactions originating from the QCD theta term. We impose vacuum alignment at both quark and h…
An effective field theory approach to two trapped particles
I. Stetcu, J. Rotureau, B. R. Barrett +1
We discuss the problem of two particles interacting via short-range interactions within a harmonic-oscillator trap. The interactions are organized according to their number of deri…
