Description of the thesis topic
The CNRS LAPP (Laboratoire d'Annecy de Physique des Particules) Institute invites applications for a doctoral position to work on the ATLAS experiment at the proton-proton Large Hadron Collider at CERN. The position will focus on comprehensive search for new phenomena with two electrons or two muons in the final state. These processes can be related by crossing symmetry to b→sll transitions, in which “flavor anomalies” have been observed in recent years. Thus their study at ATLAS may contribute to the understanding of these seemingly coherent pattern of deviations with respect to Standard Model (SM) predictions. This work will be done in collaboration with the ATLAS group in Weizmann Institute, Israel.
Position and Main Responsibilities
The successful candidate will be expected to take a leading role in
- the finalization of the ongoing Run 2 (2015-2018) exclusive searches with two leptons and additional b-jets or missing transverse momenta in the event;
- new differential cross-section measurement of the Drell-Yan process as function of the number of b-tagged jets on the Run 2 data set and its interpretation in the Standard Model Effective Field Theory framework.
- preparation of the Run 3 (2022-2025) analyses with dileptons.
The successful candidate will also contribute to one of the ongoing detector projects in the group (liquid argon calorimeter operations, HL-LHC calorimeter electronics or tracking system upgrades).
The position will start on 1st of October 2022 for the duration of three years. This position is open in the context of the CNRS-Weizmann PhD Joint Program.
The position is based at LAPP. Regular trips to Weizmann Institute, Israel and CERN, Switzerland (50 km from LAPP) are planned.
Candidates are expected to obtain/hold a Master degree in Particle Physics prior to the start of the position.
A strong experience in software development and prior experience of particle physics analysis or detector work is required.
Fluency in English, speaking and writing (B2 minimum).
Basic knowledge of French could be useful.
The LAPP is a laboratory of the Institute of Nuclear Physics and Particle Physics (IN2P3), institute of the National Center for Scientific Research (CNRS) which coordinates programs in these fields. The LAPP is a joint research unit (UMR 5814) of the CNRS and the Université Savoie Mont-Blanc (USMB). More than 150 researchers, research teachers, engineers, technicians, administrators, students and foreign visitors work there. The research conducted at the LAPP aims to study the physics of elementary particles and their fundamental interactions, as well as to explore their links with the major structures of the Universe. The LAPP is involved in the experiments of the LHC (ATLAS, LHCb), neutrinos (SuperNémo, STEREO, LBNO, etc.), astrophysics (HESS, CTA) or gravitational waves (Virgo). The location of the laboratory 50 kms from CERN, and the presence of a theoretical physics laboratory in the same premises, make it a very attractive laboratory for all scientists in this field of research. The LAPP also houses an intermediate-sized mesocenter for computation and storage, but which contributes significantly to the data processing of large physics experiments such as ATLAS, LHCb or CTA.
The ATLAS group at LAPP is currently involved in direct searches for new phenomena, precision measurements in the Higgs-boson and gauge-boson sectors as well as the upgrade of the Liquid Argon calorimeter electronics for Run 2 (2022-2025) and HL-LHC (2028+) and the construction of the new pixel detector for HL-LHC.
