摘要：
It is shown how high-order cumulants of net-charge distribution in hadronic collisions at the LHC energies can be expressed via lower-order terms under the assumption that particle-antiparticle pairs are produced in the independent local processes. It is argued and tested with the HIJING model that this assumption is typically valid for net-proton fluctuations in the case when no critical behaviour is present in the system. Values estimated in such a way can be considered as baselines for direct measurements of high-order net-charge fluctuations in real data.
