A complete set of parity- and time-reversal conserving relativistic nucleon-nucleon contact operators is identified up to the order O(p4) expansion in soft momenta p. basis also provided for corresponding non-relativistic contributing general reference frame. We show that expansions involve twenty-six independent combinations, two starting at O(p0), seven O(p2) seventeen O(p4). This gives suppo...

We present the first calculations of proton elastic and inelastic scattering in which the Pauli blocking operator contains the leading non-spherical components as well as the usual spherical (angle-averaged) part. We develop a formalism for including the contributions to the effective nucleon-nucleon interaction from the resulting new G-matrix elements that extend the usual two-nucleon spin str...

Based on the spectator expansion of multiple scattering series we employ a chiral next-to-next-to-leading order (NNLO) nucleon-nucleon interaction same footing in structure as well reaction calculation to obtain an leading-order consistent effective potential for nucleon-nucleus elastic scattering, which includes spin struck target nucleon. As example present proton off $^{12}$C.
