摘要：

We estimate the amount of collective "elliptic flow" expected at mid-rapidity in proton-proton (p-p) 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 p-p 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 p-p collisions at root s = 14 TeV.
