Analysis of the Axialvector Doubly Heavy Tetraquark States with QCD Sum Rules / Wang, Zhi-Gang
In this article, we construct the axialvector-diquark--scalar-antidiquark-type currents to interpolate the axialvector doubly heavy tetraquark states, and study them with the QCD sum rules in details by carrying out the operator product expansion up to the vacuum condensates of dimension~10..

The Large-$N$ Limit with Vanishing Leading Order Condensate for Zero Pion Mass / McLerran, Larry ; Skokov, Vladimir
It is conventionally assumed that the negative mass squared term in the linear sigma model version of the pion Lagrangian is $M^2 \sim {\mit\Lambda}_{\rm QCD}^2$ in powers of $N_{\rm c}$. [...]

Status of Exclusion Limits of the KK-parity Non-conserving Resonance Production with Updated 13 TeV LHC / Shaw, Avirup
Unequal strengths of boundary localised terms lead to non-conservation of the Kaluza--Klein (KK) parity in the 4+1 Universal Extra Dimensional model. [...]

A Ranking Method for Selection of $\eta $ Mesons in High Multiplicity Events / Bingül, A. ; Şaşmaz, U. ; Beddall, A.J.
The selection of $\eta$ mesons with a high efficiency and a high purity can be important in the formation of statistically significant invariant mass spectra in the reconstruction of short-lived particles such as $\eta' \rightarrow \pi^{+} \pi^{-} \eta$. [...]

Analysis of the $\frac {3}{2}^{\pm }$ Pentaquark States in the Diquark Model with QCD Sum Rules / Zhang, Jun-Xia ; Wang, Zhi-Gang ; Di, Zun-Yan
In this article, we construct the scalar--diquark--axialvector--diquark--antiquark-type interpolating currents, and study the masses and pole res-idues of the $J^{P}=\frac{3}{2}^{\pm}$ hidden-charmed pentaquark states with the QCD sum rules. [...]

Production of Dirac Particles in External Electromagnetic Fields / Sogut, Kenan ; Yanar, Hilmi ; Havare, Ali
Pair creation of spin-$\frac{1}{2}$ particles in Minkowski spacetime is investigated by obtaining exact solutions of the Dirac equation in the presence of electromagnetic fields and using them for determining the Bogoliubov coefficients. [...]
