"The Quest for Supersymmetry: Where do we stand?"

Symmetry considerations have played a very important role in the
contemporary theory of elementary particles. Supersymmetry was introduced as
a novel symmetry that interrelates properties of bosons and fermions. If
supersymmetry is realised in nature, every known elementary particle must
have a new super-partner, many of whose properties are determined by the
underlying theoretical scenario. Supersymmetric models have been severely
constrained by recent results from the Large Hadron Collider (LHC), most
notably by direct supersymmetry searches, flavour physics and by the
discovery of a Higgs-like particle with mass close to 125 GeV. In
particular, the ATLAS and CMS experiments have conducted a broad spectrum of
searches for Supersymmetry, by analysing LHC collision data. No hint of a
super-partner has been seen yet, so a discussion on what has been ruled out
so far and which possible theoretical avenues lie ahead in the future will
be given. The connection of supersymmetry with dark matter, a yet
unidentified component of the universe, will be addressed, too.
