Nuclear Physics Confronts Relativistic Collisions Of Isobars
read the original abstract
High-energy collisions involving the $A=96$ isobars $^{96}$Zr and $^{96}$Ru have been performed in 2018 at Brookhaven National Laboratory's Relativistic Heavy Ion Collider (RHIC) as a means to search for the chiral magnetic effect in QCD. This would manifest itself as specific deviations from unity in the ratio of observables taken between $^{96}$Zr+$^{96}$Zr and $^{96}$Ru+$^{96}$Ru collisions. Measurements of such ratios (released at the end of 2021) indeed reveal deviations from unity, but these are primarily caused by the two collided isobars having different radial profiles and intrinsic deformations. To make progress in understanding RHIC data, nuclear physicists across the energy spectrum gathered in Heidelberg in 2022 as part of an EMMI Rapid Reaction Task Force (RRTF) to address the following question. Does the combined effort of low-energy nuclear structure physics and high-energy heavy-ion physics enable us to understand the observations made in isobar collisions at RHIC?

Evidence of nuclear geometry-driven anisotropic flow in OO and Ne$-$Ne collisions at $\mathbf{\sqrt{{\textit s}_{\rm\mathbf {NN}}}}$ = 5.36 TeV
First measurements of elliptic and triangular flow in OO and Ne-Ne collisions show geometry-driven collectivity consistent with hydrodynamic predictions.

Yoctosecond imaging of the ground state of $^{129}$Xe at the Large Hadron Collider
Bayesian global fit to Xe-Xe and Pb-Pb LHC data infers nearly maximal triaxiality for the 129Xe ground state and extracts two- and three-particle correlations.

Equilibrated fraction of QCD matter in high-energy oxygen--oxygen collisions
The equilibrated core in O+O collisions overtakes the nonequilibrium corona above midrapidity multiplicity of about 20, yet corona contributions persist in central events, making pure hydrodynamics inadequate.

The size of the quark-gluon plasma in ultracentral collisions: impact of initial density fluctuations on the average transverse momentum
Volume variation with multiplicity in ultracentral collisions is small when total entropy scales with nuclear mass number, as shown by relating it to initial density fluctuation profiles.

Scaling approach to rigid and soft nuclear deformation through flow fluctuations in high-energy nuclear collisions
Triangular flow four-particle cumulants scale linearly with the fourth moment of octupole deformation, allowing the mean and variance of 238U octupole deformation to be extracted separately.

Nuclear structure and saturation effects from diffractive vector meson production
Predictions for vector meson production in light-nucleus UPCs show t-differential observables sensitive to nuclear structure models and saturation suppression that grows with nuclear mass and collision energy.
