What I will be working on:
As a distinguished LPC researcher in 2025, I will continue my work on the Higgs self-coupling, targeting the HHH production mode at the LHC. To improve the sensitivity of the CMS detector to Higgs physics in heavy flavour decays, I will develop a tagger to identify the sign of the electric charge of jets in the detector. This novel idea has the potential to significantly improve many searches and measurements in Higgs physics. Additionally, I will contribute to the HGCAL detector upgrade project, where I will test the large number of ECON production chips needed for this ambitious project.
My role in CMS past and present:
I joined CMS in 2022 after completing my PhD in ATLAS. In ATLAS, I’ve contributed to the search for the Higgs-charm coupling, in particular, I have designed the measurement to be statistically independent from he Higgs-bottom coupling measurement. My work opened the possibility to constrain the Higgs-charm coupling for the first time in the combined measurement of the Higgs boson properties. When I joined CMS as a postdoctoral fellow at Brown University, I started a new effort to search for the non-resonant HHH process in the 6 b-jets final state. This new group attracted the attention of some CMS collaborators and became a regular working group meeting. In addition, I joined the HCAL operations and served as a co-convenor of the Prompt Feedback Group in 2023. During 2022 and 2023, I served as Higgs trigger contact, where I monitored the relevant triggers for the Higgs group and also proposed and validated a new trigger strategy in 2023 and 2024 targeting HH and HHH production. As of September 2023, I am co-leading the H-bb/cc subgroup in the Higgs group, where I ensure that CMS analysers interested in the interaction of the Higgs boson with heavy quarks have the resources they need for their analyses and I help review the physics content of their work. In 2024, I joined the HGCAL ECON group at Fermilab where I contribute to the testing of the ECON chips for the phase-2 detector upgrade.
