The Researcher will work in the field of high energy nuclear physics with the ALICE experiment at the Large Hadron Collider at CERN.
The objectives will be jet quenching measurements with the ALICE experiment, including new uses of machine learning in physics analysis and data reconstruction, and to contribute to the operation of the ALICE detector during LHC Run 3
-Measure the production of inclusive jets, photon-jet correlations and heavy flavor jets.
-Use machine learning methods
-Improve existing analyses by taking advantage of the high statistics expected for LHC Run 3, by developing new labeling algorithms based on the improved accuracy of the silicon trajectrograph following its upgrade from LS2
-Interpret the results using the ROOT software
-Participate in the data collection of the ALICE detector at CERN
-Ph.D. in experimental high-energy physics or a related field
-Excellent experimental skills, including large data analysis, event reconstruction techniques, and simulation
- Expertise in software systems used in high energy physics as well as Unix operating systems, C++ and Python programming language is required.
- Experience or willingness to learn machine learning techniques is an asset for this position.
- Good communication and writing skills in English
- Ability to work both independently and collaboratively in an international team environment is required
The LPSC Grenoble (http://lpsc.in2p3.fr) is a joint research unit of about 230 people, led by the University Grenoble Alpes (UGA), CNRS/IN2P3 and the Grenoble INP School of Engineering and Management.
The researcher will be assigned to the ALICE group of the LPSC, currently composed of 4 researchers and 3 PhD students. He/she will work under the responsibility of Rachid Guernane in the framework of the ALICE project on physics analyses using LHC Run 3 data.
The researcher will also be required to establish a close collaboration with the theorists of the laboratory in order to compare the results with the QCD models.
Constraints and risks
The position will be based in Grenoble but will require regular travel to CERN (140 km from Grenoble). Other trips in France and abroad will probably be necessary.
