Measurement of high momentum H to bbar in the semileptonic ttH channel using full Run II data
This work did not become an indexed publication but I am extremely proud of the work we did with the Daniele Ruini (graduate student)
A measurement of high transverse momentum Higgs bosons decaying to a pair of b quarks and produced in association with a pair of top quarks. The analysis uses 140 fb−1 of data collected by the CMS Experiment, corresponding to the full Run II dataset. These results consider the semileptonic decay channel where one of the W bosons produced by the top quarks decays leptonically into a muon or electron and a neutrino, while the other W boson decays hadronically into a pair of quarks. An optimized selection is applied to discriminate this production mode from other standard model processes. The softdrop mass of the highest transverse momentum jet, with cone size of 0.8, is used as a natural discriminator in this boosted topology. A data-driven method is utilized to model the sum of all the background components combined. Using these techniques, a significance of 0.12 (expected 0.40) and an upper limit of 5.38 (expected 5.02+2.42−1.53) is found.

Search for pair-produced resonances decaying to quark pairs in proton-proton collisions at 13 TeV
A search for the pair production of resonances decaying to two quarks is reported. The search is conducted separately for lighter resonances between 80 and 400 GeV in mass, when the resulting diquark decay products are collimated and reconstructed as a single jet producing a dijet final state, and for heavier resonances above 400 GeV in mass, when the decay products generate pairs of hadronic jets producing a four-jet final state. In addition, a b-tagged selection is applied to target resonances with a bottom quark in the final state. The analysis uses data collected with the CMS detector at the LHC, corresponding to an integrated luminosity of 35.9 fb−1 from proton-proton collisions at a center-of-mass energy of 13 TeV. The mass spectra are analyzed for the presence of new resonant particles, and are found to be consistent with standard model expectations. The results are interpreted in the framework of R-parity-violating supersymmentry assuming the pair production of scalar top quarks decaying via the lambda_312 or the lambda_323 hadronic couplings, and upper limits are placed on the pair production cross section of top squarks as a function of the top squark mass for the two hadronic coupling scenarios.
Search for low-mass pair-produced dijet resonances using jet substructure techniques in proton-proton collisions at 13 TeV
Results from a search for paired boosted diquark resonances, using jet substructure techniques, are reported. This search uses data corresponding to an integrated luminosity of 2.7 fb−1 from proton-proton collisions at a center-of-mass energy of 13 TeV, recorded by the CMS detector at the LHC in 2015. Limits at 95% confidence level are set on the production of top squarks decaying to two light quarks in the framework of R-parity violating supersymmetry. Top squarks with masses between 80 and 240 GeV are excluded.
