AbstractWe present measurements of event-by-event fluctuations on hadron multiplicity ratios (K/pi, p/pi, K/p) in Au+Au collisions at and 200 GeV using the STAR detector at RHIC. The magnitude of dynamical fluctuations sigma (dyn) for p/pi and K/p ratios change smoothly from a large negative value at 7.7 GeV to a smaller negative value at 200 GeV while that for the K/pi ratios exhibits no significant beam energy dependence. The dynamical fluctuations related to pair production sigma (dyn) (pair) dyn for the p/K, K/p, K (-)/K (+) and p/p ratios at 200 GeV all exhibit a maximum at the mid-central collisions and decrease at the most peripheral and most central collisions.
