  "description": "<p>We report on the measurement of the size of the particle-emitting source from two-baryon correlations with ALICE in high-multiplicity pp collisions at $\\sqrt{s}=13$ TeV. The source radius is studied with low relative momentum p\u2013p, $\\stackrel{\u203e}{\\text{p}}\\phantom{\\rule{0.25em}{0ex}}\\text{\u2013}\\stackrel{\u203e}{\\text{p}}\\phantom{\\rule{0.25em}{0ex}}$, p\u2013\u039b , and $\\stackrel{\u203e}{\\text{p}}\\phantom{\\rule{0.25em}{0ex}}\\text{\u2013}\\stackrel{\u203e}{\\Lambda }\\phantom{\\rule{0.25em}{0ex}}$ pairs as a function of the pair transverse mass ${m}_{T}$ considering for the first time in a quantitative way the effect of strong resonance decays. After correcting for this effect, the radii extracted for pairs of different particle species agree. This indicates that protons, antiprotons, \u039b s, and $\\stackrel{\u203e}{\\Lambda }$ s originate from the same source. Within the measured ${m}_{T}$ range (1.1\u20132.2) GeV$/{c}^{2}$the invariant radius of this common source varies between 1.3 and 0.85 fm. These results provide a precise reference for studies of the strong hadron\u2013hadron interactions and for the investigation of collective properties in small colliding systems.</p>",
