Description

Hadronic signatures are from the most promising in the high energy physics analysis program, broadly
used for both Standard Model measurements and searches for new physics. These signatures include generic quark
and gluon jets as well as jets originating from b-quarks or tau leptons decaying hadronically. Additionally
missing transverse momentum from non-interacting particles provide an interesting probe  to search for new
physics interactions beyond the Standard Model.
Developing trigger selections that target on these signatures
is a huge challenge in the hadron colliders, due to the enormous rates these signatures contribute.

This talk
presents an overview of how we trigger on hadronic signatures on the ATLAS experiment of the LHC, outlying the
challenges of hadronic object trigger reconstruction and describing the improvements performed for the Run-2
LHC data-taking. The performance in Run-2 data is shown. We also discuss further critical developments
envisaged for the rest for the Run-2 data taking. These include two new hardware components for topological
selections at L1 and full-scan tracking in the input of the HLT.
