Abstract
The Large Hadron Collider (LHC) has been successfully delivering proton-proton collision data at the unprecedented center of mass energy of 13 TeV. An upgrade is planned to increase the instantaneous luminosity delivered by the LHC in what is called HL-LHC, aiming to deliver a total of about 3000 fb −1 of data per experiment. To cope with the expected data-taking conditions ATLAS and CMS are planning major upgrades of the detectors. Additionally, ATLAS and CMS are preparing inputs to a CERN Yellow Report that aims to summarize the physics reach for HL-LHC and will be submitted as input to the European Strategy before the end of 2018. This contribution focusses on the physics reach expected for a wide range of measurements and searches at the HL-LHC for the ATLAS and CMS experiments, including Higgs coupling, di-Higgs boson production sensitivity, Vector Boson Scattering prospects as well as discovery potential for electroweak SUSY and other exotic benchmark scenarios.
Highlights
Introduction to the HLLHC The ATLAS [1] and CMS [2] collaborations at the Large Hadron Collider (LHC) announced the discovery of a 125 GeV Higgs-like boson on 4 July 2012 [3, 4]
Further measurements and studies by both collaborations of the mass [5], the spin and parity [6, 7] as well as the production and decay rates have found no significant deviations from the Standard Model (SM) expectations [8]
In the SM, all properties of the Higgs boson are defined once its mass is known
Summary
Introduction to the HLLHC The ATLAS [1] and CMS [2] collaborations at the Large Hadron Collider (LHC) announced the discovery of a 125 GeV Higgs-like boson on 4 July 2012 [3, 4]. For a centre-of-mass energy of 14 TeV, the production cross section of pairs of 125 GeV Higgs bosons is estimated to be 39.6 fb [27].
