Figure 8

Femtoscopic radii (EGE fit) as a function of the pair transverse momentum $k_{\rm T}$ for four multiplicity classes. For comparison, radii from high-multiplicity pp collisions at $\sqrt{s}=7$ TeV are shown. Top, middle, and bottom panel show $R^{E}_{out}$, $R^{G}_{side}$, $R^{E}_{long}$ radii, respectively. The data points for the multiplicity classes 20-40% and 40-60% have been slightly shifted in $k_{\rm T}$ for visibility.
