Abstract

We estimate the amount of collective “elliptic flow” expected at mid-rapidity in proton–proton (pp) collisions at the CERN Large Hadron Collider (LHC), assuming that any possible azimuthal anisotropy of the produced hadrons with respect to the plane of the reaction follows the same overlap-eccentricity and particle-density scalings as found in high-energy heavy-ion collisions. Using a Glauber eikonal model, we compute the pp eccentricities, transverse areas and particle multiplicities for various phenomenological parameterisations of the proton spatial density. For realistic proton transverse profiles, we find integrated elliptic-flow v 2 parameters below 3% in pp collisions at \(\sqrt{s}=14\)  TeV.
