A refined HIJING initial-condition model with geometric bias from impact-parameter effects, combined with Boltzmann jet transport, describes the centrality dependence of charged-hadron suppression in 5.02 TeV Pb+Pb collisions.
CMS sets an observed upper limit of 4.4 on the HH signal strength μ_HH in the 4b final state at 13.6 TeV, improving prior LHC results by more than a factor of two in the resolved topology.
No significant excess observed in search for vector-like quark single production to Wb, setting 95% CL upper limits on κ_W as low as 0.086 near 1.4 TeV mass and excluding masses below 2.4 TeV at κ_W=0.2.
Recursive Jigsaw Reconstruction is applied to reconstruct toponium at the ttbar threshold, with two variables proposed to improve signal sensitivity.
A PINN constrained by the two-component multiplicity model learns the hard-scattering fraction from Zr+Zr events and predicts N_ch more accurately than a data-driven NN on unseen Ru+Ru and Au+Au collisions.
FASER is now running at the LHC and has started delivering first collider-based neutrino data along with searches for new light particles.
The ISO-BREAK 25 workshop report summarizes evidence and discussions on unexplained isospin symmetry breaking in nucleus-nucleus collisions and sets priorities for further work.
