Abstract

The Λ- \Lambda{\text -} and Ξ- \Xi{\text -}triton(t) momentum correlation functions, to be measured in high-energy heavy-ion collisions, are explored. Mainly, STAR detector acquired data provides an opportunity to explore the Λt \Lambda t correlation function. The Λt \Lambda t correlation functions are calculated using an isle-type and spin-averaged Λt \Lambda t potential, also, its sensitivity to changes in potential strength has also been investigated. % Besides, even though there is no experimental data on the Ξ- \Xi{\text -} triton interaction yet, I constructed Ξt\Xi t potentials based on the first principles HAL QCD and Nijmegen extended soft-core (ESC08c) model of spin- and isospin averaged ΞN\Xi N interactions in single-folding potentials (SFP) approach. Then, the Ξt\Xi t correlation functions are calculated for these two modern potentials as well as for Nijmegen hard-core model D (NHC-D) ΞN\Xi N potential. The numerical results predict that, with good measurement resolution, it might be possible to recognize different potentials with a correlation function at relatively small source sizes, i.e., R=13 R = 1-3 fm.
