Missions

The CNRS LAPP (Laboratoire d'Annecy de Physique des Particules) institute is opening a post-doctoral researcher position for a two-year postdoctoral fellowship on ATLAS, a mid-aged experiment at the Large Hadron Collider. The position aims at developing machine-learning-based tools for electroweak measurements in the Standard Model sector and extensions of those to the future coverage upgraded Phase-II ATLAS detector.

Activités

The successful candidate will join the team of physicists looking into subtle effects in diboson channels and is expected to co-supervise a PhD student studying polarisation effects in diboson Run-3 events, but also to prepare the extension of such analyses to the larger coverage provided by the future inner-tracker and to the presence of the High Granularity Timing Detector (HGTD), by using machine learning techniques (allowing for e.g. having a new category of more forward leptons).

The group has expertise in data acquisition and online software. In particular, we are involved in the operations and Phase-II upgrade of the electronics of the ATLAS Liquid Argon (LAr) calorimeters. In the coming years, the LAPP group will be in charge of developing the LAr Phase-II online software infrastructure, and to produce, test and commission the new LATOURNETT and LAr Calibration boards. Depending on the profile and interest, the successful candidate could contribute to more instrumental aspects related to the above-mentioned topics.

Compétences

— Physics: good knowledge of particle physics analysis and event reconstruction.
— Technical skills: programming in C++, Python, ROOT is required ; experience with Athena (the ATLAS reconstruction software) and recent machine learning tools are a bonus.
— Language: Fluency in written and spoken English, speaking French is a bonus.
— Team work spirit is more than welcome.

Contexte de travail

LAPP is a laboratory of the Institute of Nuclear Physics and Particle Physics (IN2P3), an institute of the National Center for Scientific Research (CNRS), which coordinates programs in these fields. LAPP is a joint research unit (UMR 5814) of the CNRS and the University of Savoie Mont-Blanc (USMB). More than 150 researchers, teacher-researchers, engineers, technicians, administrators, students and foreign visitors work there. The research carried out at LAPP aims to study the physics of elementary particles and their fundamental interactions, as well as to explore their links with the great structures of the Universe. The work of the LAPP teams aims, among other things, to understand the origin of the mass of particles, to unravel the mystery of dark matter or to determine what happened to the anti-matter present in our universe at the time of the Big Bang.
LAPP is a dynamic lab located 50-km far from CERN that hosts the detector of the ATLAS collaboration. The LAPP ATLAS team (11 physicists, 3 post-docs, 5 PhD students, 16 engineers) mostly works on Higgs physics and complementary measurements in the SM EW sector.

Contraintes et risques

Trips: Some short trips have to be planned in France and abroad, frequent trips to CERN (within 50km) are foreseen
