| Description: |
Whether or not femto-scale droplets of quark-gluon plasma (QGP) are formed in so-called small systems at high-energy colliders is a pressing question in the phenomenology of the strong interaction. For proton-proton or proton-nucleus collisions the answer is inconclusive due to the large theoretical uncertainties plaguing the description of these processes. While upcoming data on collisions of O16 nuclei may mitigate these uncertainties in the near future, here we demonstrate the unique possibilities offered by complementing O16 + O16 data with collisions of Ne20 ions. We couple both nuclear lattice effective field theory (NLEFT) and projected generator coordinate method (PGCM) ab initio descriptions of the structure of Ne20 and O16 to hydrodynamic simulations of O16 + O16 and Ne20 + Ne20 collisions at high energy. We isolate the imprints of the bowling-pin shape of Ne20 on the collective flow of hadrons, which can be used to perform quantitative tests of the hydrodynamic QGP paradigm. In particular, we predict that the elliptic flow of Ne20 + Ne20 collisions is enhanced by as much as 1.174(8)stat(31)syst for NLEFT and 1.139(6)stat(39)syst for PGCM relative to O16 + O16 collisions for the 1% most central events. At the same time, theoretical uncertainties largely cancel when studying relative variations of observables between two systems. This demonstrates a method based on experiments with two light-ion species for precision characterizations of the collective dynamics and its emergence in a small system. |
