Description
Run-I at the LHC was very successful with the discovery of a new boson
of about 125 GeV mass with properties compatible with those of the Higgs
boson predicted by Standard Model.Precise measurements of the properties of this new boson, and the
search for new physics beyond the Standard Model, are primary goals of
the just restarted LHC running at 13 TeV collision energy and all future
running at the LHC, including its luminosity upgrade, HL-LHC, that should
allow the collection of 3000 fb-1 of data per experiment.
The physics prospects with a pp centre-of-mass
energy of 14 TeV are presented for 300 and 3000 fb-1.
The ultimate precision attainable on
measurements of the couplings of the 125 GeV boson to elementary
fermions and bosons is discussed, as well as perspectives on the
searches for partners associated with it.
The electroweak sector is further studied with the analysis of the
vector boson scattering, testing the SM predictions.
Supersymmetry is one of the best motivated extensions of the Standard
Model. The current searches at the LHC have yielded sensitivity to TeV
scale gluinos and 1st and 2nd generation squarks, as well as to 3rd
generation squarks and electro-weakinos in the hundreds of GeV mass
range. Benchmark studies are presented to show how the sensitivity
improves at the future LHC runs. The prospects of searches for new
heavy bosons and dark matter candidates at 14 TeV are explored as well
as the sensitivity of searches for anomalous top decays.
For all these studies, a parameterised simulation of the upgraded
ATLAS detector is used, taking into account the expected pileup
conditions.
