Stop, hammer time! Using novel tools to nail down the top squark after Run 2
Date: Thursday, May 6th
Time: 3:30 pm - 4:30 pm
Place: Zoom:
Speaker: Dr. Daniel Spitzbart, Boston University
Abstract: Top squarks ("stops"), the superpartners of top quarks, could be a key to answer questions about the nature of the Higgs boson mass and shed light on the origin of dark matter. Predicted to have a mass that is accessible at the LHC themselves they are a prime target in searches for supersymmetry.
New analysis techniques were inspired and facilitated by the large available data set from Run 2 of the LHC, leading to unprecedented sensitivity to top squarks with masses up to 1.3 TeV.
I will present novel methods based on machine learning and elaborate algorithms, and show the latest results from these searches. By combining a comprehensive set of individual analysis channels we are able to further tighten these constraints, leading to results that will set a legacy for years to come.
