Abstract: We study the Kondo effect for a Σc (Σ ∗ c) baryon in nuclear matter. In terms of the spin and isospin (SU(2)spin × SU(2)isospin) symmetry, the heavy-quark spin symmetry and the S-wave interaction, we… read more here.

Abstract: The strong interactions among nucleons have an approximate spin-isospin exchange symmetry that arises from the properties of quantum chromodynamics in the limit of many colors, N_{c}. However this large-N_{c} symmetry is well hidden and reveals… read more here.

Abstract: Via simulating the contribution of spin-orbit interaction to nuclear masses by orthogonal Chebyshev polynomials, the mass excesses are calculated for a group of atomic nuclei characterized by the isospins of Tz = 51/2, 26, 53/2,… read more here.
