Fluctuations along freeze-out in heavy ion collisions in the presence of rotation

The quest to map the phase diagram of QCD matter is facilitated jointly by theory and experiments. Heavy ion collisions at facilities like RHIC and LHC serve to unravel the properties of strongly interacting matter not only under high temperatures (T) and baryon chemical potentials (µ_B), but also for finite rotation, parameterized by angular velocity (ω) specially important in the case of peripheral collisions. The products of the moments of conserved charges relevant for our system are plotted to show their beam energy dependence. The general trend of all the quantities plotted seem to obey the expected behaviour as reported elsewhere. The variations caused due to the inclusion of rotation are shown in the adjoining figure. For central collisions multiplicities of identified hadrons can be well fitted for certain parametrizations of T and µ's with √s and this has been obtained from the literature to qualitatively check for the effects of finite rotation on net proton, charge and strangeness distributions. Since the corresponding parametrization with rotational influence is not directly available as the data is limited exclusively to central collisions, we here juxtapose the data points only for an approximate reference instead of a direct comparison with peripheral collisions data. The latter may be used in the future for a more direct comparison
