LPC Distinguished Researcher


Mariarosaria D'Alfonso



What I will be working on:

In the past two years I have improved the HCAL local reconstruction developed for the 25ns data taking. As an LPC fellow, I will be extending this work integrating the new detector longitudinal segmentation in the global event reconstruction of CMS in view of the Run3. The improvements in the forward detector will be precious to establish a new standard on VBF jets for Higgs-like searches or Vector Boson Scattering.

My role in CMS past and present:

I was a major player in the construction of the CMS Silicon Strip Tracker: I saw the first TIB module and I left the project when the whole Tracker was ready to move to P5. During the LHC-Run1, my research program was centered on searches for new particles, forces and symmetries inspired by Supersymmetric models in both hadronic and leptonic mode. I defined the simplified models spectra for the susy interpretations of the CMS results. During the first long shutdown I worked on the Wmass precision measurement and focused on the understanding of the missing energy reconstruction and its precise calibration. With the LHC-Run2 dataset, I am searching for additional higgs bosons to test the spontaneous electroweak symmetry breaking mechanism. I am taking care of the HCAL detector performance to ensure a smooth 2018 data taking and a well planned transition during the long shutdown.
