Simulations and measurements of the transverse mode coupling instability in the LHC
Physical Review Accelerators and Beams, 2023 The High Luminosity (HL) upgrade of the Large Hadron Collider (LHC) will increase the peak luminosity at the experiments by more than a factor of 5 with respect to the LHC design value.

The role of vector boson fusion in the production of heavy vector triplets at the LHC and HL-LHC
Journal of High Energy Physics, 2022 We clarify the role of vector boson fusion (VBF) in the production of heavy vector triplets at the LHC and the HL-LHC. We point out that the presence of VBF production leads to an unavoidable rate of Drell-Yan (DY) production and highlight the subtle ...

The Evolution of Analysis Models for HL-LHC [PDF]
EPJ Web of Conferences, 2020 A quick review of how analyses were and are performed at LHC in Run1 and Run2 is proposed. A discussion then follow on how this could scale and what can be improved for Run3 and for High Lumi LHC. Critical items are highlighted and some interesting emerging technologies are discussed.

Hadron collider sensitivity to fat flavourful Z ′s for R K ∗ $$ {R}_{K^{\left(\ast \right)}} $$
Journal of High Energy Physics, 2019 We further investigate the case where new physics in the form of a massive Z ′ particle explains apparent measurements of lepton flavour non-universality in B → K (*) l + l − decays.

The CMS Trigger Upgrade for the HL-LHC [PDF]
EPJ Web of Conferences, 2020 The CMS experiment has been designed with a two-level trigger system: the Level-1 Trigger, implemented on custom-designed electronics, and the High Level Trigger, a streamlined version of the CMS offline reconstruction software running on a computer farm.

Achromatic telescopic squeezing scheme and application to the LHC and its luminosity upgrade
Physical Review Special Topics. Accelerators and Beams, 2013 A novel optics concept, the achromatic telescopic squeezing (ATS) scheme has been invented in the context of the Large Hadron Collider (LHC) upgrade studies, and chosen as the baseline scheme for the optics and layout of the recently approved high ...

, 2022 The Large Hadron-electron Collider is the opportunity for DIS at the TeV scale in the HL-LHC era. An energy recovery linac in racetrack configuration would provide 20-60 GeV electrons to collide with the HL-LHC hadron and nuclear beams, providing instantaneous luminosities around $10^{34}$ and $5\cdot 10^{32}$ cm$^{-2}$s$^{-1}$ per nucleon respectively.

Simulations of fast crab cavity failures in the high luminosity Large Hadron Collider
Physical Review Special Topics. Accelerators and Beams, 2014 Crab cavities (CCs) are a key ingredient of the high luminosity Large Hadron Collider (HL-LHC) project for increasing the luminosity of the LHC. At KEKB, CCs have exhibited abrupt changes of phase and voltage during a time period of the order of a few ...

Analysis Facilities for HL-LHC
, 2022 The HL-LHC presents significant challenges for the HEP analysis community. The number of events in each analysis is expected to increase by an order of magnitude and new techniques are expected to be required; both challenges necessitate new services and approaches for analysis facilities.

ATLAS Upgrade for the HL-LHC: meeting the challenges of a five-fold increase in collision rate
EPJ Web of Conferences, 2012 With the LHC successfully collecting data at 7 TeV, plans are actively advancing for a series of upgrades leading eventually to about five times the LHC design-luminosity some 10-years from now in the High-Luminosity LHC (HL-LHC) project. Coping with the
