Neutral kaon interferometry in Au plus Au collisions at root(S)(NN) =200GeV Academic Article uri icon


  • We present the first statistically meaningful results from two-Ks0 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=4.090.46(stat)0.31(sys) fm and =0.920.23(stat) 0.13(sys), where R and 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. 2006 The American Physical Society.
