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
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
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.

Constraining Neutrino Interaction Uncertainties for Neutrino Oscillation Measurements at the T2K Experiment / T2K Collaboration
In the context of neutrino oscillation measurements from the T2K experiment, the off-axis near detector ND280 plays a crucial role in constraining the incoming neutrino flux and neutrino-nucleus interaction cross sections. [...]

What makes spacetime spin in string theory? / Delgado, Matilda (Harvard U. (main) ; Garching, Max Planck Inst.) ; Eberhardt, Lorenz (Amsterdam U.) ; Tomašević, Marija (CERN)
Type II string theory in the absence of orientifolds requires the target spacetime $X$ to admit a spin structure. [...]
