LPC Distinguished Researcher


Abdollah Mohammadi


Kansas State University

What I will be working on:

As an LPC fellow, I plan to continue the search for Dark Matter (DM) in Leptoquark plus MET signature motivated by the newly proposed "Coannihilation Codex" model. This new DM search would complement the current generic X+MET searches carried out at LHC. Additionally I plan to contribute to the search for the Higgs boson anomalous HVV coupling in the decay of a Higgs boson to a pair of tau leptons. I also plan to be involved in the development of the high-granularity calorimeter (HGCAL) as well contribution in its test beam.

My role in CMS past and present:

I joined CMS as a PhD student in 2009. I have contributed to various domains of physics analyses including tau object commissioning, SM precision measurement and SM and BSM Higgs boson. I have conducted the first and only measurement of the W to tau nu cross section in CMS and contributed to the search for SM Higgs boson with taus in final state since my PhD until just recently which led to the observation of the SM Higgs boson to a pair of tau lepton. I have served as tau identification convener for 2 years and starting from September 2017, I have been selected as the Exotic Higgs subgroup convener. In the Extotica domains, I also have conducted the search for third generation of leptoquark and heavy right handed neutrino with 13 TeV data and have initiated a search for dark matter in mono-LQ analysis in the context of the 'coannihilation codex'. On the hardware side, I have been involved in the upgrade of the hadronic calorimeter, specifically commissioning of the calibration and readout modules of the HE and HB phase 1 upgrade.
