Abstract
We present a two-particle correlation measurement of proton- and of Λp-pairs, measured with the HADES detector in p+Nb reactions at a kinetic beam energy of 3.5 GeV. The proton-proton correlation function is used to extract the size of the region of homogeneity. Using this information together with a UrQMD transport simulation opens the possibility to study the interaction of Λp pairs in terms of spin average scattering length and effective range.
Highlights
The collision of two heavy nuclei at high energies creates a complex system, which is believed to undergo several evolution steps in time including e.g. a hydrodynamic expansion controlled by the viscosity of the system
