Simone Pagan Griso (LBNL) "Search for Supersymmetric Long-Lived Particles with the ATLAS Experiment"

March 24, 2016 @ 4:00 pm - 5:00 pm

Supersymmetry is a well motivated extension of the Standard Model of particle physics,
although its realization in nature has yet to be proven.
The main efforts at the Large Hadron Collider to probe for supersymmetry
at the electroweak mass scale focus on the so-called “prompt” signatures.
In these cases, the super-symmetric partners of the known Standard Model particles
either decay close to the production point, within the detector resolution, or
traverse the detector with no strong interaction, leaving usually a large imbalance
of momentum in the transverse plane.
In this seminar I will focus on searches for supersymmetric particles
with a significant lifetime, that could be either directly or indirectly measured.
Such particles can easily evade current constraints based on prompt signatures.
After a brief introduction on the main mechanisms leading to long-lived
particles in supersymmetric theories, I will review the experimental techniques
employed in these searches using the ATLAS detector.
I will then present an overview of the data analysis results, with a particular focus on
the most recent ones.
