Offer Description

The Laboratoire de Physique de Clermont-Ferrand (LPC) is seeking a candidate for a two-year postdoctoral position focusing on ATLAS research. The position involves studying long-lived exotic particles (LLP) and contributing to the advancement of the High Granularity Time Detector (HGTD) for phase 2 of the ATLAS detector upgrade.

The successful candidate will actively contribute to the LPC team's efforts in developing the ATLAS HGTD, an innovative detector with unprecedented temporal resolution (~40 picoseconds). This revolutionary detector is due to be installed during the intensive maintenance period preceding run 4 of the LHC. The successful candidate will play a key role in creating a qualification and certification system for the assembled modules, which will require close collaboration with the developers of the HGTD data acquisition system and a regular presence at CERN.

At the same time, the successful candidate will participate in the searches for new particles. Exotic long-lived particles (LLPs) occupy an important place in extensions of the Standard Model (SM) in particle physics, and could answer fundamental questions in this field. However, LLPs may have escaped detection in the conventional Large Hadron Collider (LHC) research programme. The search for these distinctive signatures offers a new avenue of discovery. The successful candidate will be actively involved in the search for LLPs generating displaced activity in the ATLAS calorimeters. In addition, he/she will play a key role in the development of data analysis software for LLP searches using Run 3 data, encompassing statistical analysis and preservation of results within an international collaborative framework.

– Designing and implementing the HGTD qualification system and data acquisition system, integrating the components of the data acquisition system and subjecting them to rigorous testing on a demonstrator at CERN.
– Play a central role in the testing of complex beams of HGTD modules at CERN.
– Designing and advancing the ATLAS Run-3 data analysis software for long-lived exotic particle (LLP) searches.
– Carrying out in-depth statistical analyses and preserving analytical results, contributing to the establishment of robust methodologies for re-interpretation.

The team is part of the Clermont Physics Laboratory (LPC), which also includes the LHCb, ALICE, LSST and theoretical physics teams, as well as research teams in physics applied to health, the environment and energy. The LPC is hosted by the University of Clermont Auvergne (UCA) and is part of the French National Institute for Nuclear and Particle Physics (IN2P3), a division of the French National Centre for Scientific Research (CNRS). Around half of the 160 members of the LPC work in one of the technical departments (computing, mechanics, electronics and microelectronics) or in the administrative department.

The LPC is located on the outskirts of Clermont-Ferrand, a medium-sized but dynamic town in the west of the Auvergne-Rhônes-Alpes region, 3.5 hours from CERN. The town borders the Parc Régional des Volcans d'Auvergne, recently classified as a UNESCO World Heritage Site. There are many cultural activities on offer, culminating in the International Short Film Festival (the largest short film festival in the world) every February. Clermont-Ferrand is also the birthplace of the Michelin company. The public transport network is efficient, with a tram stop right next to the LPC. The cost of living in Clermont-Ferrand is low compared with major cities such as Lyon or Paris.

The team receives substantial financial support from CNRS/IN2P3 each year, mainly covering travel costs (to CERN, workshops and conferences) and local computing costs. The CNRS provides the team with a pleasant working environment, including a dedicated local batch cluster with 200TB of disk storage. The team is a founding member of the ATLAS collaboration and has always made a significant contribution to the scintillating tile hadronic calorimeter (TileCal), as well as to physics analyses. The team is also active in the HL-LHC Phase 2 upgrade, for many years on TileCal and since 2018 on HGTD. Since 2022, it has opened up a new direction in the search for long-lived exotic particles. The team also has extensive experience in the development of artificial intelligence algorithms applied to the analysis of physics data.

It is not compulsory to speak French and free French lessons will be available. A good knowledge of English is required.
