Studied and corrected calorimeter geometry description in Run II Monte Carlo Made and analyzed physical measurements of the Central Fiber Tracker while it was being built for Run II to ensure proper construction Developed an H-matrix discriminant for τ lepton identification in Run II and maintained the related reconstruction software Performed preliminary Monte Carlo studies on a search for Chargino/Neutralino production in Run II events with three leptons involving τ Analyzed early Run II calorimeter data to improve understanding of data quality Made one of the first attempts to rediscover the Z invariant mass peak with e+eevents in Run II data for energy calibration purposes Probing g-ttbar anomalous coupling using lepton+jets ttbar events in Run I with the matrix element method (PhD thesis)
D0 (2006 present) Studied and verified the performance of the L1CalTrack triggers, newly implemented for Run IIb, for events involving τ leptons Utilizing the new triggering capability in Run IIb, designed and developed new trigger criteria for events involving τ leptons. Optimized the performance of these triggers against increased instantaneous luminosity and trigger rate limits Derived reweighting functions that modifies the transverse momentum distributions of Z boson in Alpgen Z+jets Monte Carlo to match data. The functions have been implemented in the general analysis software. Actively involved in the search for low-mass Standard Model Higgs boson production in association with a Z boson in the l+l-bb channel. Increased acceptance and efficiencies of signal events over prior results. Multiple analysis techniques, including kinematic fit, neural network and decision trees, were studied or employed in this analysis. Results based on 4.2 fb -1 of Run II data using decision trees were published in 2010.
