DOI: 10.1103/physrevc.107.045201
Abstract: In this paper, we present for the first time comprehensive and detailed results on the correspondence between the extrapolated deep inelastic structure function $g_1$ of both the proton and the neutron with the same quantity… read more here.

DOI: 10.1103/physrevc.98.064319
Abstract: We propose a particle number conserving formalism for the treatment of isovector-isoscalar pairing in nuclei with $N>Z$. The ground state of the pairing Hamiltonian is described by a quartet condensate to which is appended a… read more here.

DOI: 10.1103/physrevd.100.014509
Abstract: The electromagnetic form factors of the proton and the neutron are computed within lattice QCD using simulations with quarks masses fixed to their physical values. Both connected and disconnected contributions are computed. We analyze two… read more here.

DOI: 10.1103/physrevd.101.115041
Abstract: We analyze contributions to the electric dipole (EDM) and Schiff (SFM) moments of deuteron induced by the CP-violating three-pseudoscalar meson couplings using phenomenological Lagrangian approach involving nucleons and pseudoscalar mesons $P=\pi, K, \eta, \eta'$. Deuteron… read more here.

DOI: 10.1103/physrevlett.122.172502
Abstract: We measured the triple coincidence A(e,e^{'}np) and A(e,e^{'}pp) reactions on carbon, aluminum, iron, and lead targets at Q^{2}>1.5ββ(GeV/c)^{2}, x_{B}>1.1 and missing momentum >400ββMeV/c. This was the first direct measurement of both proton-proton (pp) and neutron-proton… read more here.
