Azimuthal Angular Decorrelation of Jets at Future High-energy Colliders / Hoş, İ. ; Saygın, H. ; Kuday, S.
The azimuthal angular decorrelation that is relevant to small-$x$ QCD physics is studied in this paper to show the BFKL effect with a recent event generator. [...]

Dual QCD Insight into BSM Hadronic Matrix Elements for $K^0$--$\bar K^0$ Mixing from Lattice QCD / Buras, Andrzej J. ; Gérard, Jean-Marc
We calculate BSM hadronic matrix elements for $K^0$--$\bar K^0$ mixing in the Dual QCD approach (DQCD). [...]

Quark Binding Potential and QGP / Pal, Shukla ; Bhattacharya, Aparajita ; Chakrabarti, Ballari ; Ghosh, Rismita
The effect of quark--antiquark potential on the dissociation energy and critical screening length of heavy meson such as $b\bar{b}$ and $c\bar{c}$ have been investigated when the respective meson is in Quark--Gluon Plasma (QGP). [...]

Massive Abelian Gauge Bosons in Front-form Hamiltonians / Głazek, Stanisław D.
It is shown how gauge bosons can be supplied with a mass term using the Higgs mechanism for the purpose of regulating Hamiltonians of Abelian gauge theories in the front form of quantum dynamics..

Transverse Momentum $p_{\mathrm {T}}$ Spectra of Strange Particles Production in Different Collisions at $\sqrt {s_{NN}}$ = 2.76, 5.02 and 7 TeV / Yassin, Hayam ; Abo Elyazeed, Eman R.
We analyse the transverse momentum $p_{\rm T}$ spectra of strange particles $K^{0}_{\mathrm s}$, ${\mit\Lambda}$, and ${\mit\Xi}^{-}$ produced in Pb+Pb collision at $\sqrt{s_{NN}}= 2.76$~TeV, $p+{\rm Pb}$ collision at $\sqrt{s_{NN}} = 5.02$~TeV, and $p+p$ collision at $\sqrt{s_{NN}}= 7$~TeV in different multiplicity events measured by the CMS experiment at the Large Hadron Collider.

2-connections, a Lattice Point of View / Bouzid, B. ; Tahiri, M.
We show that the transition laws for a 2-connection can be recovered by discretizing the base 2-space of a 2-bundle into an Euclidean hypercubic lattice. [...]

Soft Anomalous Dimension Matrices in Heavy Quark--Antiquark Hadroproduction in Association with a Gluon Jet / Szarek, E.
We compute the soft anomalous dimension (SAD) matrices for production of massive quarks $Q$ and $\bar{Q}$ in association with a gluon jet, from massless quarks $q$ and antiquarks $\bar{q}$: $q\bar{q}\rightarrow Q\bar{Q}g$, and in the gluon scattering $gg\rightarrow Q\bar{Q}g$. [...]

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..
