Impact of Inclusive Electron Ion Collider Data on Collinear Parton Distributions
/ Armesto, Néstor (Santiago de Compostela U., IGFAE) ; Cridge, Thomas (DESY) ; Giuli, Francesco (CERN) ; Harland-Lang, Lucian (University Coll. London) ; Newman, Paul (Birmingham U.) ; Schmookler, Barak (UC, Riverside) ; Thorne, Robert (University Coll. London) ; Wichmann, Katarzyna (DESY)
A study is presented of the impact of simulated inclusive Electron Ion Collider Deep Inelastic Scattering data on the determination of the proton and nuclear parton distribution functions (PDFs) at next-to-next-to-leading and next-to-leading order in QCD, respectively. The influence on the proton PDFs is evaluated relative to the HERAPDF2.0 set, which uses inclusive HERA data only, and also relative to the global fitting approach of the MSHT20 PDFs. [...]

Overview of the LHeC and FCC-he accelerator concepts
/ Holzer, B J (CERN) ; André, K D J (CERN) ; Armesto, N (Santiago de Compostela U., IGFAE) ; Bogacz, S A (Jefferson Lab) ; Hanstock, D (Liverpool U.) ; Hounsell, B (Liverpool U.) ; Klein, M (CERN ; Liverpool U.) ; Kostka, P (CERN ; Liverpool U.) ; Smith, M W R (Liverpool U.) ; von Witzleben, T (CERN)
The Large Hadron–Electron Collider (LHeC) is designed to move the field of deep inelastic scattering (DIS) to the energy and intensity frontier of particle physics. Exploiting energy- recovery technology, it collides a novel, intense electron beam with a proton or ion beam from the High-Luminosity Large Hadron Collider (HL-LHC). [...]

Snowmass 2021 whitepaper: Proton structure at the precision frontier
/ Amoroso, S. (DESY) ; Apyan, A. (Brandeis U.) ; Armesto, N. (Santiago de Compostela U., IGFAE) ; Ball, R.D. (U. Edinburgh, Higgs Ctr. Theor. Phys.) ; Bertone, V. (IRFU, Saclay) ; Bissolotti, C. (Argonne) ; Bluemlein, J. (DESY) ; Boughezal, R. (Argonne) ; Bozzi, G. (Cagliari U. ; INFN, Cagliari) ; Britzger, D. (Munich, Max Planck Inst.) et al.
An overwhelming number of theoretical predictions for hadron colliders require parton distribution functions (PDFs), which are an important ingredient of theory infrastructure for the next generation of high-energy experiments. This whitepaper summarizes the status and future prospects for determination of high-precision PDFs applicable in a wide range of energies and experiments, in particular in precision tests of the Standard Model and in new physics searches at the high-luminosity Large Hadron Collider and Electron-Ion Collider [...]

An Experiment for Electron-Hadron Scattering at the LHC
/ André, K.D. J. (CERN ; Liverpool U.) ; Aperio Bella, L. (DESY) ; Armesto, N. (Santiago de Compostela U., IGFAE) ; Bogacz, S.A. (Jefferson Lab) ; Britzger, D.

Novel considerations are presented on the physics, apparatus and accelerator designs for a future, luminous, energy frontier electron-hadron ($eh$) scattering experiment at the LHC in the thirties for which key physics topics and their relation to the hadron-hadron HL-LHC physics programme are discussed. Demands are derived set by these physics topics on the design of the LHeC detector, a corresponding update of which is described. [...]

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. [...]

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 $v_2$. [...]
