Neutral Kaon Interferometry in Au+Au collisions at √sN N = 200 GeV
We present the first statistically meaningful results from two-K0s interferometry in heavy-ion collisions at sNN‾‾‾‾√=200 GeV. A model that takes the effect of the strong interaction into account has been used to fit the measured correlation function. The effects of single and coupled channels were explored. At the mean transverse mass 〈mT〉=1.07 GeV, we obtain the values R=4.09±0.46(stat)±0.31(sys) fm and λ=0.92±0.23(stat)±0.13(sys), where R and λ are the invariant radius and chaoticity parameters, respectively. The results are qualitatively consistent with mT systematics established with pions in a scenario characterized by a strong collective flow.
