At a beam energy of 1.76AGeV, the reaction Ar + KCl was studied with the High Acceptance Di-Electron Spectrometer ( HADES) at SIS18/GSI. A high-statistics and high-purity Lambda sample was collected, allowing for the investigation of Lambda p correlations at low relative momenta. The experimental correlation function is compared to corresponding model calculations allowing the determination of the space-time extent of the Lambda p emission source. The Lambda p source radius is found to be slightly smaller than the pp correlation radius for a similar collision system. The present Lambda p radius is significantly smaller than that found for Au + Au/Pb + Pb collisions in the AGS, SPS, and RHIC energy domains but larger than that observed for electroproduction from He. Taking into account all available data, we find the Lambda p source radius to increase almost linearly with the number of participants to the power of one-third.", optnote="ISI:000281017300001", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=393), last updated on Fri, 20 May 2016 14:28:35 +0000", issn="0556-2813", doi="10.1103/PhysRevC.82.021901", opturl="http://arxiv.org/abs/1004.2328", opturl="https://doi.org/10.1103/PhysRevC.82.021901", archivePrefix="arXiv", eprint="1004.2328", language="English" }
