Job description

Offer DescriptionThe ALICE group of Laboratoire de Physique Clermont Auvergne invites applications for a postdoctoral research position. ALICE (A Large Ion Collider Experiment) is one of four major experiments installed at the LHC, CERN. It is mainly dedicated to the study of the behavior of matter produced in heavy-ion collisions. According to Quantum ChromoDynamics, the theory of the strong interaction, when the temperature and/or the baryon density reached in a collision are sufficiently high, a quark-gluon plasma (QGP) can be produced. Quarkonia are one of the most relevant probes used to characterize the properties of the QGP, their production rate being modified by the presence of the hot and dense medium formed in the collisions. Quarkonia are mesons composed of a quark and an antiquark of the same flavor, charm (c) or beauty (b). Their ground states are the J/Ψ (ccbar) and the ϒ (bbar). Quarkonia can be produced in hadron collisions at high energy, especially in the proton-proton (pp) and Pb-Pb collisions occurring at the Large Hadron Collider (LHC) at CERN. Production mechanisms of quarkonia in dense hadronic environment are not understood, and especially the production associated with charged particle multiplicity and jets.ALICE is equipped with a forward muon spectrometer which allows to measure quarkonia in their di-muon (2 muons) decay mode. In 2022, the LHC entered a new exploitation phase, RUN 3, for which all detectors of the experiment were upgraded to sustain the highest interaction rate reached. The upgraded tracking of muons in ALICE aims at providing a sufficient pointing resolution to the vertex in order to disentangle the muonic decay of charmonia states produced at the interaction point from those originating from the decay of bottomonia and characterized by a displaced secondary vertex. This improved tracking paradigm is possible thanks to the coupling of the Muon Spectrometer with a new highly segmented silicon pixel detector, the Muon Forward Tracker (MFT), placed in front of the ALICE hadron absorber and very close to the interaction point.The recruited candidate will join the MFT project and RUN 3 data analysis.– Contribution to the software development of global muon physics related analyses. Global muons are muons with reconstructed components in the muon spectrometer and in the MFT.
– Leading role in the matching strategy between the MFT and the muon spectrometer, performance studies and analysis cut optimization related to global muons.
– Physics analysis in the scope of quarkonium production studies in dense hadronic environment and take benefit of the large data sample collected by the ALICE experiment in proton-proton and Pb-Pb collisions during RUN 3.
– Contribution to the experimental work of the ALICE operations and more specifically with the MFT project.
– The successful candidate is expected to rapidly take on scientific responsibilities in either area.The successful candidates will join the ALICE collaboration, an international collaboration composed of more than 2000 physicists from all continents. He/She will be based at LPCA (CNRS/IN2P3/UCA), Clermont-Ferrand, France in the ALICE group. The ALICE-Clermont group is currently composed by 7 (teacher)-researcher and a PhD student with a long-standing expertise of the Muon Spectrometer, the Muon Forward Tracker and quarkonia measurements. The successful candidate will have the opportunity to participate in national events and to represent the ALICE LPCA group in international conferences as well as regular trips to CERN to pursue the experimental work and participate in the collaboration meetings.RequirementsResearch Field Physics Education Level PhD or equivalentLanguages FRENCH Level BasicResearch Field Physics Years of Research Experience NoneAdditional InformationEligibility criteria– Expert in relativistic heavy-ion collision physics, as demonstrated by a PhD in the field – Expert in object-oriented programming
