DOI: 10.1093/ptep/ptz034
Abstract: We apply the Marchenko method of quantum inverse scattering to study nucleon scattering problems. Assuming a $\beta/r^2$ type repulsive core and comparing our results to the Reid93 phenomenological potential we estimate the constant $\beta$, determining… read more here.

DOI: 10.1103/physrevd.101.056021
Abstract: We calculate the complete T-matrices of pion-nucleon ($\pi N$) scattering to the third order in heavy baryon SU(3)-flavor chiral perturbation theory. The baryon mass in the chiral limit $M_0$ and the low-energy constants (LECs) are… read more here.

DOI: 10.1103/physrevd.102.023017
Abstract: Based on the Kompaneets approximation, we develop a robust methodology to calculate spectral redistribution via inelastic neutrino-nucleon scattering in the context of core-collapse supernova simulations. The resulting equations conserve lepton number to machine precision and… read more here.

DOI: 10.1103/physrevd.99.094505
Abstract: The lattice QCD simulation of $NJ/\psi$ and $N\eta_c$ scattering is performed at $m_\pi\simeq 266~$MeV in channels with all possible $J^P$. This includes $J^P=3/2^\pm$ and $5/2^\pm$ where LHCb discovered $P_c(4380)$ and $P_c(4450)$ pentaquark states in proton$-J/\psi$… read more here.

DOI: 10.1103/physrevlett.130.071902
Abstract: Chiral perturbation theory and its unitarized versions have played an important role in our understanding of the low-energy strong interaction. Yet, so far, such studies typically deal exclusively with perturbative or nonperturbative channels. In this… read more here.

DOI: 10.3390/sym14102090
Abstract: In the E6 inspired U(1)N extension of the minimal supersymmetric (SUSY) standard model (MSSM), a single discrete Z˜2H symmetry permits suppressing rapid proton decay and non-diagonal flavor transitions. If matter parity and Z˜2H symmetry are… read more here.
