The event-by-event fluctuations in net-lambda multiplicity distribution from the BES-I showed that the cumulant ratios have a similar energy and multiplicity dependence compared to those for protons, and the observed deviation from Poisson baseline can be attributed to baryon number and strangeness conservations. It is also known from the previous work that the derived freeze-out parameters show sensitivity to the quark content of the hadrons, implying a quark mass dependence in the process of hadronization. We present the lambda fluctuation analysis in Au+Au collisions at the lowest collision energy (√sNN =3.0 GeV), where we continue the comparison with proton fluctuations and study the behaviour of both baryons, specifically in terms of their difference in quark content and applicable conservation laws.
