Post-doctoral researcher (M/F) in particle physics.

Job Description

Missions

During the 2-year post-doctoral position, the researcher will participate to simulation studies of the future electromagnetic calorimeter (PicoCal) of the LHCb experiment, under design for the LS3 enhancement and Upgrade II phases of the experiment. She/he will also participate to studies related to an electromagnetic calorimeter, GRAiNITA, designed for the future FCC-ee experiments. The candidate will in addition participate to physics analyses with LHCb data of charmless B decays containing 0 or photons in the final state. She/he will be member of the LHCb team at IJCLab and work with the members of the team for the studies mentioned above. The post-doctoral researcher will document her/his work, publish it and present it in international conferences.

Activity

The main activities will be:
• Develop the simulation and digitization software for the LHCb PicoCal in Run 4 and Run 5
• Compare the PicoCal detector simulated performances with test beam data
• Evaluate the performances of the PicoCal detector for future physics measurements
• Develop the simulation software for the GRAiNITA detector for FCC-ee experiments
• Analyze LHCb data for charmless B decays involving neutral particles

Your Profil

Skills

Education: PhD in experimental particle physics, with less than 2 years experience after the PhD
• Programming: skills in Python, C++ and ROOT
• Language: fluency in spoken and written English. Some level of French could be useful.
• Good communication skills and ability to work in a team.
• Knowledge of simulation tools (Geant4, …) is preferred but not mandatory

Your Work Environment

The Irène Joliot-Curie Physics Laboratory of 2 Infinities (IJCLab) is a UMR under the supervision of the CNRS (IN2P3), the University of Paris-Saclay and the University of Paris is located on the campus of the University of Paris -Saclay in Orsay. The laboratory is located on the campus of the Université Paris-Sud, Université Paris-Saclay in Orsay. The campus is located 20 km south of Paris and easily accessible by RER in 35 minutes.
IJCLab was born in 2020 from the merger of five units (CSNSM, IMNC, IPN, LAL, LPT). The staff is made up of nearly 560 permanent (340 engineers, technicians and administrators and 220 researchers and teacher-researchers) and approximately 200 non-permanent including 120 doctoral students. The research themes of the laboratory are nuclear physics, high energy physics, theoretical physics, astroparticles, astrophysics and cosmology, particle accelerators, energy and the environment and health. IJCLab has very significant technical capacities (around 280 IT) in all the major fields required to design, develop / implement the experimental devices necessary for its scientific activity, as well as the design, development and use of instruments.

The researcher will work in the LHCb team of the laboratory which is involved in the LHCb collaboration, in the operation of the current electromagnetic calorimeter and in the design of the future one (PicoCal). She/he will also be part of the IJCLab GRAiNITA team which is mostly embedded in the LHCb group.
The LHCb group includes around 15 physicists (permanent researchers, post-docs and doctoral students). The GRAiNITA team is composed of 2 researchers, one doctoral student and 4 engineers.
