Anisotropic flow in fixed-Target 208Pb+20Ne collisions as a probe of quark-gluon plasma

The System for Measuring Overlap with Gas (SMOG2) at the LHCb detector enables the study of fixed-target ion-ion collisions at relativistic energies (√𝑠NN∼100 GeV in the center of mass). With input from ab initio calculations of the structure of 16O and 20Ne, we compute 3+1⁢D hydrodynamic prediction...

Riassunto:The System for Measuring Overlap with Gas (SMOG2) at the LHCb detector enables the study of fixed-target ion-ion collisions at relativistic energies (√𝑠NN∼100 GeV in the center of mass). With input from ab initio calculations of the structure of 16O and 20Ne, we compute 3+1⁢D hydrodynamic predictions for the anisotropic flow of Pb+Ne and Pb+O collisions to be tested with upcoming LHCb data. This will allow the detailed study of quark-gluon plasma formation as well as experimental tests of the predicted nuclear shapes. Elliptic flow (𝑣2) in Pb+Ne collisions is greatly enhanced compared to the Pb+O baseline due to the shape of 20Ne, which is deformed in a bowling-pin geometry. Owing to the large 208Pb radius, this effect is seen in a broad centrality range, a unique feature of this collision configuration. Larger elliptic flow further enhances the quadrangular flow (𝑣4) of Pb+Ne collisions via nonlinear coupling, and impacts the sign of the kurtosis of the elliptic flow vector distribution (𝑐2⁡{4}). Exploiting the shape of 20Ne proves thus an ideal method to investigate the formation of quark-gluon plasma in fixed-target experiments at LHCb, and demonstrates the power of System for Measuring Overlap with Gas as a tool to image nuclear ground states.
