Dihadron production in DIS at NLO: the real corrections by Edmond Iancu, Yair Mulian

“…We first compute the tree-level cross-section for the production of the quark-antiquark-gluon system and then deduce the real NLO corrections to dihadron production by integrating out the kinematics of the gluon. …”

The complex heavy quarkonium potential with the Gribov–Zwanziger action by Manas Debnath, Ritesh Ghosh, Najmul Haque

“…The real and imaginary parts of the heavy quarkonium complex potential are obtained from the one-loop effective static gluon propagator. The one-loop effective gluon propagator is obtained by calculating the one-loop gluon self-energies containing the quark, gluon, and ghost loop. …”

Impact of parton energy loss and nPDFs on J/ψ production in proton-nucleus collisions by Li-Hua Song, Peng-Qi Wang, Yin-Jie Zhang

“…By the recent EPPS21 nPDFs, a leading order phenomenological analysis of J/ψ production cross-section ratios is performed for E866 experimental data with considering the parton energy loss effect following Landau-Pomeranchuk-Migdal (LPM) regime. The gluon transport coefficient qˆg extracted from the E866 data in 0.20<xF<0.65 region is qˆg=0.35±0.01 GeV2/fm with χ2/ndf=1.01, which indicates that the significantly better-constrained gluon distributions provided by EPPS21 contribute to accurately determining the gluon energy loss. …”

Additional moments and x-space approximations of four-loop splitting functions in QCD by S. Moch, B. Ruijl, T. Ueda, J. Vermaseren, A. Vogt

“…These results, obtained using physical quantities in inclusive deep-inelastic scattering, have been and will be used to validate conceptionally much more challenging determinations of these splitting functions from off-shell operator matrix elements (OMEs). For the quark-gluon and gluon-gluon splitting functions, which have yet to be computed to higher N using OMEs, we construct approximations based on our moments and endpoint constraints, where we present new large-x results for the gluon-gluon case. …”

A new form of QCD coherence for multiple soft emissions using Glauber-SCET by Aditya Pathak

“…Abstract Amplitude-level factorization for a soft gluon emission has long been understood in terms of a product of loop-expanded soft-gluon currents and hard scattering matrix elements, both of which are infrared (IR) divergent. …”

All-order celestial OPE in the MHV sector by Tim Adamo, Wei Bu, Eduardo Casali, Atul Sharma

“…Abstract On-shell kinematics for gluon scattering can be parametrized with points on the celestial sphere; in the limit where these points collide, it is known that tree-level gluon scattering amplitudes exhibit an operator product expansion (OPE)-like structure. …”

Measurement of the H→WW*→lvlv decay using same-flavour leptons in pp collisions at √s = 13 TeV with the ATLAS detector by Karava, K

“…Higgs boson production via gluon-gluon fusion and vector-boson fusion in the $\textit{H} \rightarrow \textit{WW*} \rightarrow l\nu l\nu$ decay mode is measured in the same-flavour channel, where the two leptons are either both electrons or both muons. …”

Unpolarized transverse-momentum dependent distribution functions of a quark in a pion with Minkowskian dynamics by W. de Paula, T. Frederico, G. Salmè

“…The Bethe-Salpeter equation for a pseudoscalar bound-system, with i) a ladder kernel with massive gluons, ii) dynamically-dressed quark mass function and iii) an extended quark-gluon vertex, is solved in Minkowski space by using the Nakanishi integral representation of the Bethe-Salpeter amplitude. …”

Transport coefficients of heavy quarkonia comparing with heavy quark coefficients by Juhee Hong, Su Houng Lee

“…For quarkonium at rest in plasmas the longitudinal gluon part of the color-singlet self-energy diagram is sufficient to determine the leading-order thermal width, whereas the momentum dependence is obtained from the transverse gluon channel. …”
