Abstract:
It is an interesting time in particle physics. On the one hand the
discovery of the Higgs boson at the LHC has been a tremendous success
for consolidating the Standard Model. On the other hand, many questions
remain unanswered. Why is the Higgs boson mass so light and where is the
"new physics" we expect at the TeV scale? Can we produce dark matter at
colliders and is the Higgs boson somehow connected to the dark sector?
Recent results from LHCb and other experiments measuring decays of
b-quarks show hints of possible lepton flavour universality violation.
What does this imply for the search program at ATLAS? During Run 2 of
the LHC, the ATLAS experiment has collected an unprecedented sensitive
dataset to answer many of these questions. In this talk, I will discuss
some of the highlights of the new results released by ATLAS so far in
the areas listed above, including searches using long-lived and
challenging unconventional signatures. I will also give a brief outlook
on what's in store for Run 3 and beyond.
