Signatures of collective flow in high multiplicity pp collisions

Understand

A blast-wave parametrization, including a full set of hadronic resonances, is used to model a small system, with total particle multiplicity comparable to the one measured in the high-multiplicity pp collisions at the LHC.

• Calculations are preformed for three cases: with negligible, regular and strong radial flow on the blast-wave hypersurface.
• We investigate the effects of flow on inclusive p_T spectra as well as on 1D and 3D femtoscopic radii for pions.
• Special emphasis is put on the role of pions from resonance decays.
