Description
Run-I at the LHC was very successful with the discovery of a new boson
with properties compatible with those of the Higgs boson predicted by
Standard Model. Precise measurements of the boson properties, and the
discovery of 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. The physics prospects with a pp centre-of-mass energy of 14 TeV are presented for 300 and 3000 fb-1 at the
high-luminosity LHC. 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.
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. A considerable fraction of the
parameter space for a wide variety of other BSM models has been probed
with the 8 TeV data and initial 13 TeV data. 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 and
di-boson production.
For all these studies, a parameterised simulation of the upgraded
ATLAS detector is used, taking into account the expected pileup
conditions.
