We report the results of the femtoscopic analysis of pairs of identical pions measured in p-Pb collisions at
√sNN = 5.02 TeV. Femtoscopic radii are determined as a function of event multiplicity and pair momentum in
three spatial dimensions. As in the pp collision system, the analysis is complicated by the presence of sizable
background correlation structures in addition to the femtoscopic signal. The radii increase with event multiplicity
and decrease with pair transverse momentum. When taken at comparable multiplicity, the radii measured in p-Pb
collisions, at high multiplicity and low pair transverse momentum, are 10%–20% higher than those observed in
pp collisions but below those observed in A-A collisions. The results are compared to hydrodynamic predictions
at large event multiplicity as well as discussed in the context of calculations based on gluon saturation.

Azimuthally-differential pion femtoscopy relative to the third harmonic event plane in Pb–Pb collisions at √sNN = 2.76 TeV
ALICE Collaboration (Elsevier B.V., 2018)Azimuthally-differential femtoscopic measurements, being sensitive to spatio-temporal characteristics of the source as well as to the collective velocity fields at freeze out, provide very important information on the ... -
One-dimensional charged kaon femtoscopy in p-Pb collisions at √sNN = 5.02 TeV
ALICE Collaboration (American Physical Society, 2019)The correlations of identical charged kaons were measured in p-Pb collisions at √sNN=5.02 TeV by the ALICE experiment at the LHC. The femtoscopic invariant radii and correlation strengths were extracted from one-dimensional ... -
Investigation of the p–Σ0 interaction via femtoscopy in pp collisions
ALICE Collaboration (Elsevier, 2020)This Letter presents the first direct investigation of the p–Σ0 interaction, using the femtoscopy technique in high-multiplicity pp collisions at s=13 TeV measured by the ALICE detector. The Σ0 is reconstructed via the ... -
Scattering Studies with Low-Energy Kaon-Proton Femtoscopy in Proton-Proton Collisions at the LHC
ALICE Collaboration (American Physical Society, 2020)The study of the strength and behavior of the antikaon-nucleon ((K) over bar N) interaction constitutes one of the key focuses of the strangeness sector in low-energy quantum chromodynamics (QCD). In this Letter a unique ... -
Pion–kaon femtoscopy and the lifetime of the hadronic phase in Pb−Pb collisions at √sNN = 2.76 TeV
ALICE Collaboration (Elsevier B.V., 2021)In this paper, the first femtoscopic analysis of pion–kaon correlations at the LHC is reported. The analysis was performed on the Pb–Pb collision data at √sNN=2.76 TeV recorded with the ALICE detector. The non-identical ...
