Farrah Simpson


Brown University

What I will be working on:

I will work on new developments in the analysis and triggers for long-lived particle (LLP) searches using displaced jets in Run 3. I will also test MaPSA prototypes at Fermilab and help establish testing of MaPSAs at Brown University. These new developments (DNN-based displaced-jet tagging, triggers for low-HT displaced jets, secondary vertex finding improvements) are aimed at filling important gaps in current LLP searches and will improve the sensitivities to important BSM signatures e.g. exotic decays of Higgs boson to LLPs.

My role in CMS past and present:

Since joining CMS Collaboration in 2017, I have participated in analysis of Run 2 data, b-tagging performance, CMS Open Data support, and silicon detector characterization for the Outer Tracker in the High Luminosity LHC (HL-LHC) era. I have studied heavy VLQ top quark with exotic charge +53, X5/3, with final state signature in the single-lepton channel using Run 2 data. I have started a new direction of study, with new exotic X5/3 decays to BSM particles, instead of SM W t decay. In addition, at Brown University, I have characterized Silicon strip sensors to be used for the CMS upgrade for the HL-LHC. I also currently serve as a member of the U.S. CMS Diversity, Equity, and Inclusion (DEI) committee. I have served as the student representative on the NSBP board (2020-2022) and have appeared on various APS webinars relating to D&I in HEP.
