Probing collective effects in hadronisation with the extremes of the underlying event

T Martin, P Skands, S Farrington - The European Physical Journal C, 2016 - Springer
We define a new set of observables to probe the structure of the underlying event in hadron
collisions. We use the conventional definition of the “transverse region” in jet events and, for …

Revealing the source of the radial flow patterns in proton–proton collisions using hard probes

A Ortiz, G Bencédi, H Bello - Journal of Physics G: Nuclear and …, 2017 - iopscience.iop.org
In this work, we propose a tool to reveal the origin of the collective-like phenomena
observed in proton–proton collisions. We exploit the fundamental difference between the …
