Query: Cumulants of event-by-event net-strangeness distributions in Au+Au
  collisions at $\sqrt{s_\mathrm{NN}}$=7.7-200 GeV from UrQMD model   Fluctuations of conserved quantities, such as baryon, electric charge and
strangeness number, are sensitive observables in heavy-ion collisions to search
for the QCD phase transition and critical point. In this paper, we performed a
systematical analysis on the various cumulants and cumulant ratios of
event-by-event net-strangeness distributions in Au+Au collisions at
$\sqrt{s_{NN}}$=7.7, 11.5, 19.6, 27, 39, 62.4 and 200 GeV from UrQMD model. We
performed a systematical study on the contributions from various strange
baryons and mesons to the net-strangeness fluctuations. The results demonstrate
that the cumulants and cumulant ratios of net-strangeness distributions
extracted from different strange particles show very different centrality and
energy dependence behavior. By comparing with the net-kaon fluctuations, we
found that the strange baryons play an important role in the fluctuations of
net-strangeness. This study can provide useful baselines to study the QCD phase
transition and search for the QCD critical point by using the fluctuations of
net-strangeness in heavy-ion collisions experiment. It can help us to
understand non-critical physics contributions to the fluctuations of
net-strangeness.
