Figure 1: Fancy way of showing that R-Hadrons seem unlikely to be produced at the LHC with masses less than 1 TeV. (we have one event that accounts for the move in observed limit compared to expectations on the plots).

ATLAS Long-lived particle searches 2012

I was involved in the search for long-lived coloured particles in ATLAS, aka. R-Hadrons in 2009-2012. My main roles this year has been the design and implementation of the analysis, data-driven background estimation and statistical hypothesis testing.
