Momentum dependent nucleon-nucleon contact interaction from a relativistic Lagrangian
A complete set of parity- and time-reversal conserving relativistic nucleon-nucleon contact operators is identified up to the order O(p4) of the expansion in soft momenta p. A basis is also provided for the corresponding non-relativistic operators contributing in the general reference frame. We show...
