Missions

The LAPP (Laboratoire d'Annecy de Physique des Particules) institute invites applications for a post-doctoral position to work on the ATLAS experiment at the proton-proton Large Hadron Collider at CERN. The position is focused on the development of effective-field theory (EFT) interpretations of ATLAS Run 2 measurements and of machine-learning (ML) techniques.

Activities

The selected candidate is expected to join the current LAPP group effort on the EFT interpretation of the Run 2 Higgs boson measurements. The objective is to extend these activities to also cover multiboson measurements and exotic searches, and in the longer term to develop a general framework for EFT interpretations including other measurements. In parallel, the candidate will work to improve the sensitivity of input analyses to EFT effects, in particular through the use of new selections based on ML techniques.
A contribution to work on ATLAS upgrade activities can also be considered.

The position is for two years, and is financed through a grant from the ENIGMASS laboratory of excellence program (http://enigmass.in2p3.fr). The position is based at LAPP, with the possibility to travel to CERN as needed.

Skills

Ph. D. diploma in particle physics obtained less than 2 years before the start of the position.
Experience with machine learning, multi-parameter fitting and BSM phenomenology would be appreciated.

Work Context

LAPP is a joint research unit of the CNRS/IN2P3 institute and the Universite Savoie Mont Blanc (USMB), located in Annecy. It hosts about 140 people, including 44 physicists. The laboratory is involved in many large international collaborations working on accelerator physics (ATLAS and LHCb on the LHC at CERN), astrophysics (Virgo, AMS, HESS, CTA, LSST) and neutrino experiments (STEREO, SuperNemo, DUNE). The location of LAPP, 50 km from CERN, and the presence of the theory laboratory LAPTh on the same campus make it an attractive location for research in particle physics and astrophysics. LAPP hosts a computing and storage facility integrated in the LHC Grid and has built expertise in data storage and processing, especially for analysis.

The LAPP/ATLAS group has played an important role in the construction, commissioning and operation of the ATLAS Liquid Argon (LAr) calorimeter. It is strongly involved in the upgrade of the LAr and Pixel detectors towards Run 3 and the HL-LHC. The group has long-standing contributions in the Higgs boson physics, in particular through Higgs coupling measurements in the H->γγ decay and the search for Higgs boson pair production; multiboson physics, in particular in the WZ final state; and exotic searches in the dilepton final state. The group is also making increasing use of ML-based techniques, in particular in the Higgs boson and WZ analyses.

Constraints and risks

Some short trips have to be planned in France and abroad
