Description
Three different experimental techniques used in the measurements of two-particle, quantum-statistical (Bose-Einstein) femtoscopic correlations in proton-proton collisions at 13 TeV are introduced and discussed. Each one of them adopts a different analysis approach, with variable degrees of dependence on Monte Carlo event generator models. These are employed for estimating and correcting the non-Bose-Einstein contributions (resonances and mini-jets) that contaminate the signal sample. All of them, however, return values for the resulting one-dimensional fit parameters (lengths of homogeneity and correlation intensity) that are consistent within the experimental uncertainties in the analysis. These methods are successfully applied in the investigation of minimum bias, as well as of high multiplicity events.
