 Energy Frontier DIS at CERN: the LHeC and the FCC-eh / Holzer, Bernhard (CERN) ; André, Kevin D J (CERN ; Liverpool U.) /LHeC Collaboration ; FCC-eh Study Group Collaboration The Large Hadron-electron Collider (LHeC) at CERN is a design study in the context of the LHC luminosity upgrade project, HL-LHC, to establish electron-proton/nucleus collisions with centre-of-mass energies in the TeV regime and luminosities in the order of 10^34𝑐𝑚−2𝑠−1. It implies the construction of an energy recovery linac in racetrack configuration to provide an intense 50 GeV electron beam that will collide with the HL-LHC hadron beams.

 The Gamma Factory path to high-luminosity LHC with isoscalar beams / Krasny, M W (Paris U., VI-VII ; CERN) ; Petrenko, A (Novosibirsk, IYF ; CERN) ; Płaczek, W (Jagiellonian U. (main)) There are two main ways to increase LHC luminosity without upgrading CERN injectors: (1) modification of beam-collision optics and (2) reduction of beam transverse emittance. The former is followed in the ongoing high-luminosity upgrade of the LHC (HL-LHC), while the latter, applicable only to ion beams, is described in this contribution [...] SISSA, 2021 - 6 p. - Published in : PoS ICHEP2020 (2021) 690 Fulltext: PDF; In : 40th International Conference on High Energy Physics (ICHEP), Prague, Czech Republic, 28 Jul - 6 Aug 2020, pp.690

 Noble liquid calorimetry at the LHC and prospects of its application in future collider experiments / Aleksa, Martin (CERN) Calorimetry is an important measurement technique in experimental particle physics. Although calorimeters based on liquefied noble gases were first proposed 50 years ago, they continue to play an important role in modern particle physics and have substantially contributed to the discovery of the Higgs boson at the Large Hadron Collider (LHC) at CERN in 2012.. 2021 - 4 p. - Published in : Europhys.

 Machine Detector Interface for FASER / Lefebvre, Helena (JAI, UK) ; Gibson, Stephen (JAI, UK) ; Nevay, Laurie (JAI, UK) /FASER Collaboration The ForwArd Search ExpeRiment (FASER) is a planned small-scale experiment designed for the search of light and weakly-interacting particles at the Large Hadron Collider (LHC). The FASER detector will be located along the beam collision axis, $480\,$m downstream from the ATLAS interaction point (IP), in an unused service tunnel.
