Partial-wave unitarity and long-range interactions / Plestid, Ryan (CERN) ; Lasanta, Pablo Quílez (CERN)
Theories with massless particles contain $t$-channel (forward scattering) singularities that cause standard fixed order expressions for partial-wave amplitudes to be ill-defined. [...]

Observation of centrality-dependent dijet transverse momentum imbalance in O+O and Ne+Ne collisions at $\ensuremath{\sqrt{s_{\mathrm{NN}}}} = 5.36$ TeV with the ATLAS detector / ATLAS Collaboration
The ATLAS experiment presents an observation of a centrality-dependent dijet transverse momentum imbalance in O+O and Ne+Ne collisions at a nucleon–nucleon center-of-mass energy of 5.36 TeV at the Large Hadron Collider. [...]

Measurements of charged-particle pseudorapidity and transverse momentum distributions in O+O and Ne+Ne collisions at $\sqrt{s_{_\text{NN}}} = 5.36$ TeV with the ATLAS detector / ATLAS Collaboration
Measurements of charged-particle transverse momentum spectra, multiplicity, and mean transverse momentum are presented as a function of pseudorapidity and collision centrality in O+O and Ne+Ne collisions at $\sqrt{s_{_\text{NN}}}= 5.36$ TeV using 27.7 $\mu\text{b}^{-1}$ and 53.1 $\mu\text{b}^{-1}$ data sets recorded by the ATLAS experiment at the LHC.
