Feasibility studies of conserved charge fluctuations in Au-Au collisions with CBM

We present the CBM physics performance study for measurements of the higher order cumulants of the net-proton multiplicity distributions. These observables are proxy for net-baryon fluctuations and are commonly used to study the phase structure of QCD phase diagram. The simulation is done for Au + Au collision at beam kinetic energy E$_{lab}$ = 10 AGeV. The cumulants of net-proton distributions have been calculated at midrapidity (|Δy| = 1) for the transverse momentum range 0.2 < pT < 2.0 GeV/c. The centrality dependence of cumulants of net-proton upto order four is presented. The efficiency and detector effects are corrected using unfolding techniques. This work shows that the higher order cumulants of net-proton can be measured using the CBM detector.
