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. [...]

The LHC Mass Limits for the SU(2)$_{\rm L+R}$ Vector Resonance Triplet of a Strong Extension of the Standard Model / Gintner, Mikuláš ; Juráň, Josef
In this paper, we derive the mass exclusion limits for the hypothetical vector resonances of a strongly interacting extension of the Standard Model using the most recent upper bounds on the cross sections for various resonance production processes. [...]
