abstract = {We study the influence of global baryon number conservation
on the non-critical baseline of net baryon cumulants in
heavy-ion collisions in a given acceptance, accounting for
the asymmetry between the mean-numbers of baryons and
antibaryons. We derive the probability distribution of net
baryon number in a restricted phase space from the canonical
partition function that incorporates exact conservation of
baryon number in the full system. Furthermore, we provide
tools to compute cumulants of any order from the generating
function of uncorrelated baryons constrained by exact baryon
number conservation. The results are applied to quantify the
non-critical baseline for cumulants of net proton number
fluctuations obtained in heavy-ion collisions by the STAR
collaboration at different RHIC energies and by the ALICE
collaboration at the LHC. Furthermore, volume fluctuations
are added by a Monte Carlo procedure based on the centrality
dependence of charged particle production as measured
experimentally. Compared to the predictions based on the
hadron resonance gas model or Skellam distribution a clear
suppression of fluctuations is observed due to exact
baryon-number conservation. The suppression increases with
the order of the cumulant and towards lower collision
energies. Predictions for net proton cumulants up to the
eight order in heavy-ion collisions are given for
experimentally accessible collision energies.},
