Femtoscopy of identified particles at STAR

We present new measurements of Λ - Λ correlations, which are closely related to the H-dibaryon: a six quark state predicted by Jaffe [R. Jaffe, Phys. Rev. Lett. 38 (1977) 195], in Au + Au collisions at sNN=200 GeV from the STAR experiment. Fits to different potential models are discussed and the extracted scattering length and effective range are also presented. We also present a spherical harmonic decomposition of the pion-kaon correlation function for 0-5% centrality in Au + Au collisions at sNN=200 GeV. Finally, we discuss results from azimuthal HBT for collision energies in the range 7.7-200 GeV.
