DOI: 10.1103/physrevc.97.054322
Abstract: Equation of state (EOS) of pure neutron matter (PNM) is studied in QCD sum rules (QCDSR). It is found that the QCDSR results on EOS of PNM are in good agreement with predictions by current… read more here.

DOI: 10.1103/physrevd.104.054030
Abstract: Form factors of the weak Ξc → Ξ(Λ) transitions are calculated within the light cone QCD sum rules. The pollutions coming from the contribution of the negative parity Ξc baryon is eliminated by considering the… read more here.

DOI: 10.5506/aphyspolb.48.2013
Abstract: In this article, we construct the scalar-diquark-axialvector-diquark-antiquark type interpolating currents, and study the masses and pole residues of the $J^{P}=\frac{3}{2}^{\pm}$ hidden-charmed pentaquark states with the QCD sum rules. In calculations, we use the formula $\mu=\sqrt{M^2_{P}-(2{\mathbb{M}}_c)^2}$… read more here.
