Description
We report on the results of a femtoscopic analysis with identical pions measured by ALICE in the collisions of protons and lead ions.
The technique of femtoscopy, based on intensity interferometry (also known as Hanbury-Brown Twiss interferometry, or HBT) allows one to relate a pair momentum difference to the space-time characteristics of the sources created in particle collisions.
The femtoscopic analysis is performed using both the spherical harmonics decomposition and the 3D Cartesian representation. HBT radii, which reflect the size the source, are obtained by fitting the resulting correlation function. We present the dependence of these radii on the pair transverse momentum and the multiplicity of the event and describe the observed scalings.
