Open Position PhD Position in Atlas Group

About IFAE

The Institut de Física d’Altes Energies (IFAE) is a public consortium of the Generalitat de Catalunya, the Autonomous Government of Catalonia, and the Universitat Autònoma de Barcelona (UAB, a public university) whose main objective is to carry out research and to contribute to the development of high energy physics from a theoretical, experimental and technological point of view. IFAE has the status of a “University Institute" attached to the UAB and its premises are within the campus of the University.

About the Collider Physics group

The Collider Physics group at IFAE is focused on the scientific exploitation of the Large Hadron Collider (LHC) at CERN. This is research line that started in 1992, when IFAE joined the ATLAS Collaboration at the LHC. The ATLAS detector was designed to explore a wide range of phenomena predicted by the Standard Model (SM) of particle physics, while also maximizing their sensitivity to beyond-the-SM processes. It is expected that these investigations will provide answers to open questions in our description of Nature such as the origin of the particle masses, the mechanism for electroweak symmetry breaking, or the presence of a new underlying symmetry (e.g., supersymmetry) that could explain the nature of dark matter or the unification of forces at very high energies. The design, construction and operation of the ATLAS detector, online event selection, event reconstruction and data analysis, all require world-wide efforts, which are reflected in the size of the ATLAS Collaboration, formed by 177 institutions from 40 countries. Its members are a team of physicists, engineers, technicians, students and support staff from around the world. It is one of the largest collaborative efforts ever attempted in science, with over 5500 members and almost 3000 scientific authors. With a 33-year involvement in the ATLAS experiment, IFAE has played mayor roles in the construction and operation of the Tile Hadronic Calorimeter (TileCal), the preparation of the High-Level Trigger infrastructure and physics selection algorithms, and the physics analyses. IFAE currently maintains a strong presence in the ATLAS experiment, with major responsibilities on the maintenance and operation of the TileCal hadronic calorimeter and the Level-1 Topological Trigger system, and participates in the Pixel detector upgrade. The group has also developed an exciting and broad research program that includes precision measurements of the top quark (e.g., four-top-quark production) and the Higgs boson (e.g., top-Higgs Yukawa coupling, di-Higgs production), and searches for new phenomena beyond the Standard Model (e.g., supersymmetry, vector-like fermions, leptoquarks, additional light or heavy Higgs bosons, etc). During Run 3 of the LHC, which started in July 2022 and will last till mid 2026, the centre-of-mass energy of proton-proton collisions has been increased to 13.6 TeV and the total delivered integrated luminosity will reach ~550 fb-1. With the increase of both energy and integrated luminosity with respect to Run 2, more stringent tests of the SM and more sensitive searches for new phenomena will be possible. IFAE is in a privileged position to analyse the ATLAS data, with strong synergies with IFAE’s Theory Division and significant computing resources from the PIC computing center.
