Query: Femtoscopy of identified particles at STAR   We present new measurements of $\Lambda-\Lambda$ correlations, which are
closely related to $H$-dibaryon: a six quark state predicted by Jaffe (1977),
in Au+Au collisions at $\sqrt{s_{NN}}$ = 200 GeV from the STAR experiment. Fits
to different potential models are discussed and extracted scattering length and
effective range are also presented.We also present spherical harmonic
decomposition of pion-kaon correlation function for 0-5% centrality in Au+Au
collision at $\sqrt{s_{NN}} = 200$ GeV. In addition, we also discuss results
from azimuthal HBT for beam energies 7.7-200 GeV.
