Description
In recent years heavy-ion collisions have noted that a preference for both a deformed proton and deformed nuclei are seen in comparing flow observables to relativistic viscous hydrodynamic calculations. Thus far, all deformations of nuclei have only considered the ground state of the nucleus. In the case of XeXe collisions, it was found that the deformed Xenon nucleus increase elliptical flow in very central collisions ~0-5%. In PbPb collisions a similar discrepancy was also found where triangular flow is consistently under-predicted by hydrodynamics calculations. In this talk, the first excited state of Pb nuclei that has a pear shape is considered, which has the effect of increasing triangular flow in central PbPb collisions, which aids in understanding the v3 puzzle in ultracentral PbPb collisions at the LHC.
