Quenching of hadron and photon spectra in heavy-ion collisions from RHIC to LHC

TL;DR

This paper discusses how parton energy loss affects hadron and photon spectra quenching in heavy-ion collisions, highlighting differences between RHIC and LHC energies and emphasizing the importance of baseline measurements in p-Pb collisions.

Contribution

It provides a comparative analysis of parton energy loss effects from RHIC to LHC and underscores the need for precise baseline measurements in p-Pb collisions.

Findings

Parton energy loss causes significant quenching of hadron spectra.

Differences in quenching effects are expected between RHIC and LHC energies.

Baseline p-Pb measurements are crucial for accurate interpretation.

Abstract

The generic features of parton energy loss effects on the quenching of single hadron spectra in heavy-ion collisions are discussed, paying attention to the expected differences from RHIC to LHC. The need for precise baseline measurements in p-Pb collisions at the LHC is also emphasized. Finally I briefly mention the production of prompt photons in heavy-ion collisions as well as some open questions.
