Tracking requirements and detector technologies @ FCC-ee

Abstract:

The Future Circular Collider (FCC-ee) offers unprecedented opportunities for both precise measurements at the Z pole and in the Higgs sector and search for new physics through high-luminosity electron-positron collisions. Fully exploiting this physics potential requires an ultra-precise tracking system capable of vertexing, momentum measurement, reconstruction of displaced vertices and particle identification. That put considerable demands on the detector technologies and a super control of the systematic uncertainties. Some benchmark analyses are chosen to study the dependence of their sensitivity on some aspects of the detector performance. This talk explores the status of the IDEA detector proposal and subdetectors technologies to cope with the requirements and ensure the relevant performance.

About the speaker:

Prof. N. De Filippis made a fundamental contribution to the discovery of the 125GeV boson and measurement of its properties with the CMS experiment at the LHC by developing an analysis to look for a Higgs boson decaying into two gauge Z bosons and then into charged leptons. Along the path of shading light on the reality of the Higgs mechanism, he worked on constraints on Higgs self-couplings via the non-resonant double Higgs production (for several final states), and on the search for BSM physics via the resonant double Higgs production at the LHC. Prof. De Filippis leads currently also the effort for the project of a drift chamber as the main tracking device for the IDEA detector proposal at FCC-ee. He is also involved in inspecting the performance of machine learning tools to improve the signal to background performance for physics analyses, by using high performance computing.

Starting from From 2018 he has been associate professor at the Physics Department of Politecnico di Bari and Visiting Courtesy Professor at Florida State University, Tallahassee, US. He was CMS LPC Distinguished Researcher at the LHC Physics Centre (LPC) Fermilab, Batavia, US in 2018 and 2019. In 2011 he was Associate fellow grant by INFN and CERN to work at CERN. He was researcher with a "contrat a duree determinee" financed by the CNRS at “Laboratoire Leprince-Ringuet”, “Ecole Polytechnique” (Palaiseau, France) between 2007 and 2009.
