The ratios of bulk observables, such as harmonic flow v 2 and v 3 , between high-energy 96 Ru+ 96 Ru and 96 Zr+ 96 Zr collisions were recently argued to be a clean probe of the nuclear structure differences between 96 Ru and 96 Zr. Using a transport model simulation of isobar collisions, we quantify this claim from the dependence of the ratios v 2 , Ru / v 2 , Zr and v 3 , Ru / v 3 , Zr on various final state effects, such as the shear viscosity, hadronization and hadronic cascade. Although the v 2…

Scaling approach to nuclear structure in high-energy heavy-ion collisions

In high-energy heavy-ion collisions, the initial condition of the produced quark-gluon plasma (QGP) and its evolution are sensitive to collective nuclear structure parameters describing the shape and

Directed flow of light hadrons in Au+Au and isobar collisions at $\sqrt{s_{\textrm{NN}}}=$ 200 GeV

We study the origin of directed flow of light hadrons produced in Au+Au and isobar collisions at RHIC energy. A tilted initial source is coupled to the (3+1)-dimensional viscous hydrodynamic model

Precision tests of the nonlinear mode coupling of anisotropic flow via high-energy collisions of isobars

Valuable information on the dynamics of expanding fluids can be inferred from the response of such systems to perturbations in their initial geometry. We apply this technique in high-energy 96 Ru+ 96
