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 $\eta' \rightarrow \pi^{+} \pi^{-} \eta$. [...]

Corrections to (Pseudo)Scalars Decay into a Fermion Pair from Gravitational Torsion / Rojas Abatte, Felipe ; Zamora-Saa, Jilberto ; Castillo-Felisola, Oscar ; Díaz, Bastian ; et al
We study the contribution of the torsion-descendent four-fermion contact interaction to the decay width of a neutral (pseudo)scalar field into a fermion pair. [...]

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. [...]
