Both institutes are founding members of the CMS experiment and played central
roles in the major scientific breakthroughs achieved by the collaboration
since the start of LHC operations in 2010. The LLR is located at the Ecole
Polytechnique campus in Palaiseau. This is a joint CNRS-Ecole Polytechnique
unit involving 120 people two fields of research that support each other both
conceptually and technically: particle physics and very high energy gamma-ray
astronomy. The group is one of the key actors in the discovery of a Higgs
boson and the measurement of its properties. The group is also strongly
involved in the developments for the LHC Phase 2 upgrades and in particular in
the design of the HGCAL and the Level-1 Trigger system. Our groups have
pioneered the development of sophisticated trigger systems and have very
extensive expertise in different aspects of these technologies.
Title: Development of advanced low-latency algorithms for high energy physics
The Compact Muon Solenoid experiment aims to study physics at the high-energy
frontier with the proton-proton collisions produced by the Large Hadron
Collider (LHC) at CERN. The characterization of the Higgs sector, as well as
the search for new physics will require the full capabilities of the LHC.
Upgrades are foreseen along the way to reach much higher instantaneous
luminosities during the Phase-2 of the LHC, also refered to as the high-
luminosity LHC (HL-LHC), starting in 2028. The CMS group of the Laboratoire
Leprince Ringuet (LLR) is opening a PhD thesis position to perform research
work within the joint CNRS-Imperial College (UK) program. This thesis
proposes to develop sophisticated low latency algorithms based on artificial
intelligence (AI). The huge volumes of data produced in particle physics
experiments, which are highly structured, well understood and open, provide an
ideal test bed for advanced AI algorithms. Because of the very high volumes of
data (in excess of 100Tb/s), the electronics used in particle physics
detectors has traditionally been application-specific, but over the last
decade advances in technology mean that flexible common processing platforms,
including generic and flexible firmware/software frameworks to facilitate
algorithm development and deployment, can now be used in many cases. This PhD
thesis proposes to design sophisticated and powerful FPGA trigger algorithms
to capture collision events displaying interesting physics signatures. The
objective is to exploit the fine-grained information provided by the first
imaging calorimeter (HGCAL) to be implemented in such HEP experiement. The
studies are embedded in a larger project to commission and test the first
prototypes of the HGCAL trigger system at CERN. A large-scale test is planned
at a dedicated integration centre, where a fully equipped slice of the HGCAL
electronics will be available in the future. The studies proposed in this
thesis also include the development of data analyses to conduct searches in
the Higgs sector and new physics signatures from exotic long-lived particles.
Both subjects constitute highlights of the HL-LHC physics programme. Common
analysis tools are used in the existing CMS software and will be used by the
student to develop a dedicated analysis framework in collaboration with other
PhD student within the LLR and Imperial College London teams currently working
on these topics. The collaboration will extend to the study of dedicated
trigger reconstruction techniques using HGCAL data for these final states. The
sensitivity extracted from these studies will be used to evaluate the impact
of the trigger algorithm developed. The combination of technical activities
and data analysis will allow the PhD candidate to gain expertise in varied
aspects of this research field. The candidate will participate to meetings and
workshops to be held at CERN and Imperial College London.
