Neutral Kaon Interferometry in Au+Au collisions at sqrt(s_NN) = 200 GeV

Abstract

We present the first statistically meaningful results from two-K0s interferometry in heavy-ion collisions. 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 channel were explored. At the mean transverse mass m_T = 1.07 GeV, we obtain the values R = 4.09 +- 0.46 (stat.) +- 0.31 (sys) fm and lambda = 0.92 +- 0.23 (stat) +- 0.13 (sys), where R and lambda are the invariant radius and chaoticity parameters respectively. The results are qualitatively consistent with m_T systematics established with pions in a scenario characterized by a strong collective flow.
