New QCD Sum Rules for Nucleon Axial Vector Coupling Constants
Frank X. Lee, Derek B. Leinweber, Xuemin Jin
New QCD sum rules for the nucleon axial-vector current coupling constants are derived. One set is derived from a generalized correlator of spin-1/2 interpolating fields, and the ot…
Recovering Relativistic Nuclear Phenomenology from the Quark-Meson Coupling Model
Xuemin Jin, B. K. Jennings
The quark-meson coupling (QMC) model for nuclear matter, which describes nuclear matter as non-overlapping MIT bags bound by the self-consistent exchange of scalar and vector meson…
Isospin Breaking in the Nucleon Isovector Axial Charge from QCD Sum Rules
Xuemin Jin
The isospin breaking in the nucleon isovector axial charge, , are calculated within the external field QCD sum-rule approach. The isospin violations arising from the differe…
New QCD Sum Rules for In-Medium Nucleons
Derek B. Leinweber, Xuemin Jin, R. J. Furnstahl
New QCD sum rules for nucleons in nuclear matter are derived from a mixed correlation function of spin-1/2 and spin-3/2 interpolating fields. These sum rules allow a determination…
