EXTRAORDINARIO", Notar Día y hora, "System size dependence of quantities sensitive to parton energy loss measured with ALICE at the LHC

ALICE, A Large Ion Collider Experiment, is one of the largest experiments
in the world (around 2000 people from 39 countries) devoted to study the
properties of the strongly-interacting Quark-Gluon Plasma (sQGP) produced
in heavy-ion collisions at the LHC energies. Over the last years, we have
pioneered several techniques for the characterization of the
high-multiplicity pp events, which recently unveiled unexpected
heavy-ion-like features. This motivates the extension of the ALICE
high-energy pp physics program to the full operation period during the LHC
Run 3. One of the main physics motivation is the study of high-density QCD
effects and search for sQGP in high multiplicity pp collisions.
In this seminar, I will show a set of new preliminary ALICE results aimed
at contributing to the development of a unified picture of particle
production and QCD dynamics from small (pp and p-Pb collisions) to large
(heavy nuclei collisions) systems. The charged-particle production in the
jet-like region is studied as a function of the largest transverse
momentum of the event, as well as the activity in the transverse region of
the di-hadron correlations (RT). The analysis has been performed in pp,
p-Pb and Pb-Pb data at sqrt(sNN)=5.02 TeV. The potential role of
Multiparton Interactions in p-Pb and Pb-Pb collisions will be discussed.
The search for jet quenching signatures in small systems is performed
considering hadrons at large transverse momentum. The pp and p-Pb results
are compared to analogous measurements in heavy-ion collisions.  A Monte
Carlo study aimed at extending this analysis to events with extremely high
RT will be presented. Finally, our plans for the analysis of Run 3 data
will be discussed.
