“…Track merging effects suppress the correlation function at low q inv . To eliminate this effect, we require the tracks in a pair to be well separated (the average separation in the silicon strip detector region must be greater than 100 μm) in addition to the cuts used in the previous analysis [5]. The systematic uncertainty due to the two-particle effects was estimated by varying the cuts and does not exceed 8%.…”

“…In order to achieve high kaon identification purity, only tracks with the momentum from 45 to 160 GeV/c were selected. Charged kaons were identified with the likelihood to be a kaon at least three times exceeding any other particle hypothesis [5]. The electrons were eliminated from the analysis using the transition radiation detector which was placed before RICH.…”

Abstract. The space and time extents of the particle emitting source created in collisions of particles with nuclei can be measured using a correlation femtoscopy method. In this paper we show the preliminary measurements of K ± K ± correlation functions in 600 GeV/c Σ − , π − and 540 GeV/c p interactions with carbon and copper nuclei. The one-dimensional correlation functions are parameterized by a Gaussian form. The dependencies of the charged kaon emitting source radii on the different h+A collisions are presented.

We report on the first measurement of pΛ and pp correlations via the femtoscopy method in p+Nb reactions at √ sNN = 3.18 GeV, studied with the High Acceptance Di-Electron Spectrometer (HADES). By comparing the experimental correlation function to model calculations, a source size for pp pairs of r0,pp = 2.02 ± 0.01(stat) +0.11 −0.12 (sys) fm and a slightly smaller value for pΛ of r0,Λp = 1.62 ± 0.02(stat) +0.19 −0.08 (sys) fm is extracted. Using the geometrical extent of the particle emitting region, determined experimentally with pp correlations as reference together with a source function from a transport model, it is possible to study different sets of scattering parameters. The pΛ correlation is proven sensitive to predicted scattering length values from chiral effective field theory. We demonstrate that the femtoscopy technique can be used as valid alternative to the analysis of scattering data to study the hyperon-nucleon interaction.
