The Large Hadron-Electron Collider at the HL-LHC
/ FCC-he Study Group Collaboration
The Large Hadron electron Collider, LHeC, is the means to move deep inelastic physics following HERA to the energy frontier of particle physics as it is being exploited by the HL-LHC. The paper presents a thorough update of the initial LHeC Conceptual Design Report (CDR) published in 2012. [...]

Unveiling the yoctosecond structure of the QGP with top quarks
/ Apolinário, Liliana (LIP, Lisbon ; Lisbon, CFTP) ; Milhano, Guilherme (LIP, Lisbon ; Lisbon, CFTP ; CERN) ; Salgado, Carlos A (Santiago de Compostela U., IGFAE) ; Salam, Gavin (CERN)
Top quarks have recently been measured for the first time in nuclear collisions. With most of the integrated luminosity of the LHC PbPb programme still to be recorded and promising projections for the future HL-LHC, HE-LHC or FCC, top quark observables will be measured with good precision and become an excellent probe of the QGP.

Medium-induced jet evolution for an expanding QGP
/ Adhya, Souvik Priyam (Calcutta, VECC) ; Salgado, Carlos A (CERN ; Santiago de Compostela U. ; Santiago de Compostela U., IGFAE) ; Tywoniuk, Konrad (CERN)
We will analyse the modification to the gluon distribution function for an expanding medium for Eq.(10). In addition, we will incorporate this modified gluon distributionfunction to study the kinematic rate equation to arrive at analytical expressions of the modified splitting function [3, 6]. [...]

Constraining energy loss from high-$p_{\rm T}$ azimuthal asymmetries
/ Andres, Carlota (Jefferson Lab) ; Armesto, Néstor (Santiago de Compostela U., IGFAE) ; Niemi, Harri (Jyvaskyla U. ; Helsinki Inst. of Phys.) ; Paatelainen, Risto (Helsinki Inst. of Phys. ; CERN) ; Salgado, Carlos A. (Santiago de Compostela U., IGFAE)
The nuclear modification factor $R_{\rm AA}$ has been satisfactorily described by various jet quenching models. Nonetheless, all these formalisms, until very recently, underpredicted the high-$p_{\rm T}$ (> 10 GeV) elliptic flow $v_2$. [...]

Future heavy-ion facilities: FCC-AA

The operation of the Future Circular Collider (FCC) with heavy ions would provide Pb-Pb and p-Pb collisions at sqrt{s_NN}= 39 and 63 TeV, respectively, per nucleon-nucleon collision, with projected per-month integrated luminosities of up to 110/nb and 29/pb, respectively. This document outlines the unique and broad physics opportunities with heavy ions at the energy frontier opened by FCC..

Report from Working Group 5 : Future physics opportunities for high-density QCD at the LHC with heavy-ion and proton beams
/ Citron, Z. (Ben Gurion U. of Negev) ; Dainese, A. (INFN, Padua) ; Grosse-Oetringhaus, J.F. (CERN) ; Jowett, J.M. (CERN) ; Lee, Y.-J. (MIT) ; Wiedemann, U.A. (CERN) ; Winn, M. (AIM, Saclay ; Orsay, LAL) ; Andronic, A. (Munster U.) ; Bellini, F. (CERN) ; Bruna, E. (INFN, Turin) et al.
The future opportunities for high-density QCD with ion and proton beams at the LHC are presented. Four major scientific goals are identified: the characterisation of the macroscopic long wavelength Quark-Gluon Plasma (QGP) properties with unprecedented precision, the investigation of the microscopic parton dynamics underlying QGP properties, the development of a unified picture of particle production and QCD dynamics from small (pp) to large (nucleus–nucleus) systems, the exploration of parton densities in nuclei in a broad (x, Q2) kinematic range and the search for the possible onset of parton saturation.

Factorization of in-medium parton branching beyond the eikonal approximation
/ Apolinário, Liliana (LIP, Lisbon) ; Armesto, Néstor (Santiago de Compostela U., IGFAE) ; Milhano, José Guilherme (LIP, Lisbon ; CERN) ; Salgado, Carlos A (Santiago de Compostela U., IGFAE)
The description of the in-medium modifications of partonic showers is at the forefront of current theoretical and experimental efforts in heavy-ion physics. The theory of jet quenching, a commonly used alias for the modifications of the parton branching resulting from the interactions with the QGP, has been significantly developed over the last years.

Probing jet decoherence in heavy ion collisions
/ Casalderrey-Solana, Jorge (Oxford U., Theor. Phys.) ; Mehtar-Tani, Yacine (Washington U., Seattle) ; Salgado, Carlos A (Santiago de Compostela U., IGFAE ; Santiago de Compostela U.) ; Tywoniuk, Konrad (CERN)
We suggest to use the SofDrop jet grooming technique to investigate the sensitivity of jet substructure to color decoherence in heavy ion collisions. We propose in particular to analyze the two-prong probability angular distribution as a probe of the transition between the coherent and incoherent energy loss regimes. [...]
