The ΛΛ Correlation Function in Au+Au collisions at sqrt{s_(NN)}= 200 GeV
read the original abstract
We present $\Lambda\Lambda$ correlation measurements in heavy-ion collisions for Au+Au collisions at $\sqrt{s_{NN}}= 200$ GeV using the STAR experiment at the Relativistic Heavy-Ion Collider (RHIC). The Lednick\'{y}-Lyuboshitz analytical model has been used to fit the data to obtain a source size, a scattering length and an effective range. Implications of the measurement of the $\Lambda\Lambda$ correlation function and interaction parameters for di-hyperon searches are discussed.

Probing the hadronic molecular nature of the $\Omega(2012)$, $\Omega(2380)$, and $\Omega_c(3120)$ via femtoscopy correlation functions
Correlation function calculations with coupled-channel potentials produce low-momentum enhancements that the authors interpret as signatures of the molecular structure of Ω(2012), Ω(2380), and Ωc(3120).
