\textit{(Color online)} Invariant mass distribution of $\mathrm{p}\pi^-$ ($\overline{\mathrm{p}}\pi^+$) to obtain the \La (\aLa) signal. The dashed lines set the selection width used in the analysis.

\textit{(Color online)} The raw correlation function compared to Pythia 6 Perugia 2011 simulations for \pP (\textit{left}), \pL (\textit{center}) and \LL (\textit{right}) pairs.

\textit{(Color online)} Comparison of radii obtained for different charged particle multiplicity intervals in the \pp collision system at $\sqrt{s}=7$\,TeV~\cite{PhysRevD.84.112004,Abelev:2012sq, 2012151}. The error bars correspond to statistical and the shaded regions to the systematic uncertainties. The black point is the radius obtained in this analysis with \pP, \pL and \LL pairs, while the gray bar corresponds to the range of covered $m_{\mathrm{T}}$ in this analysis.
\textit{(Color online)} The \pP (\textit{left}), \pL (\textit{center}) and \LL (\textit{right}) correlation function with a simultaneous fit with the NLO expansion (red line) for the scattering parameter of \pL~\cite{Haidenbauer:2013oca}. The dashed line denotes the linear baseline. After the fit is performed the LO~\cite{POLINDER2006244} parameter set (green curve) is plugged in for the \pL system and the scattering length obtained from~\cite{Adamczyk:2014vca} for the \LL system (cyan curve).
\textit{(Color online)} Number of standard deviations $n_{\sigma}$ of the modeled correlation function for a given set of scattering parameters (effective range $d_0$ and scattering length $f_0$) with respect to the data, together with various model calculations~\cite{ND, NF, NSC89, NSC97, ESC08, Ehime1, Ehime2, fss1, fss2, FG, HKMYY} and measurements~\cite{Adamczyk:2014vca}. The gray shaded area corresponds to the region where the Lednick\'{y} model predicts a negative correlation function for \pp collisions at $\sqrt{s} = 7\,$TeV.
