title: "Aux Figure 7h" of "Two-particle Bose-Einstein correlations in pp collisions at ${\sqrt{s} = 13}$ TeV measured with the ATLAS detector at the LHC"

description: The single-ratio two-particle correlation functions, C<sub>2</sub><sup>data</sup>(Q), at 7 TeV for the minimum-bias (MB) events using the unlike-charge particle (UCP) pairs reference sample for n<sub>ch</sub> - intervals∶ (a) 2 &lt; n<sub>ch</sub> ≤ 9, (b) 10 &lt; n<sub>ch</sub> ≤ 18, (c) 19 &lt; n<sub>ch</sub> ≤ 27, (d) 28 &lt; n<sub>ch</sub> ≤ 36, (e) 37 &lt; n<sub>ch</sub> ≤ 45, (f) 46 &lt; n<sub>ch</sub> ≤ 54, (g) 55 &lt; n<sub>ch</sub> ≤ 63, (h) 64 &lt; n<sub>ch</sub> ≤ 72, (i) 73 &lt; n<sub>ch</sub> ≤ 81, (j) 82 &lt; n<sub>ch</sub> ≤ 90, (k) 91 &lt; n<sub>ch</sub> ≤ 113, and (l) 114 &lt; n<sub>ch</sub> ≤ 136.

description: Two-particle Bose-Einstein correlations in pp collisions at √s=13 TeV measured with the ATLAS detector at the LHC.

This paper presents studies of Bose-Einstein correlations (BEC) in proton-proton collisions at a centre-of-mass energy of 13 TeV, using data from the ATLAS detector at the CERN Large Hadron Collider. Data were collected in a special low-luminosity configuration with a minimum-bias trigger and a high-multiplicity track trigger, accumulating integrated luminosities of 151 $\mu$b$^{-1}$ and 8.4 nb$^{-1}$ respectively. The BEC are measured for pairs of like-sign charged particles, each with $|\eta|$ &lt; 2.5, for two kinematic ranges: the first with particle $p_T$ &gt; 100 MeV and the second with particle $p_T$ &gt; 500 MeV. The BEC parameters, characterizing the source radius and particle correlation strength, are investigated as functions of charged-particle multiplicity (up to 300) and average transverse momentum of the pair (up to 1.5 GeV). The double-differential dependence on charged-particle multiplicity and average transverse momentum of the pair is also studied. The BEC radius is found to be independent of the charged-particle multiplicity for high charged-particle multiplicity (above 100), confirming a previous observation at lower energy. This saturation occurs independent of the transverse momentum of the pair.
