Offer Description

Particle physics is about the structure and origin of matter and interactions. The scalar sector linked to the Higgs boson plays a special role, and could be a gateway to new physics.

This is a major area of research at CNRS/ CNRS Nuclei & Particles, explored in particular with the ATLAS and CMS experiments at the CERN Large Hadron Collider (LHC). The current operation of the LHC (Run 3), and the preparation of experiments for its high-luminosity phase (HL-LHC, 2029-2041), mobilize almost 200 physicists and as many technical staff at CNRS Nuclei & Particles. All the data collected will enable many advances to be made in our understanding of the scalar sector, but a dedicated electron-positron collider, known as the Higgs factory, will offer a much-needed gain in precision. This machine has been identified as a priority by the European strategy and could take shape in the form of the FCC project at CERN. CNRS Nuclei & Particles intends to play a leading role in the definition of detectors for such a machine. The institute has a wealth of experience and expertise in microelectronics, microtechnology and mechanics for pixel detectors.

IPHC's CMS team is fully committed to these studies at the LHC, and IPHC's C4PI platform, in close collaboration with the PICSEL/FCC team, is an undisputed leader in the field of CMOS pixel sensors. It has played a pioneering and visionary role in the development and maturation of this technology, from the earliest stages of R&D to its realization in current experiments, and continues to prepare future projects, in partnership with other CNRS Nuclei & Particles units.

The articulation of a national effort around a vertex detector for the future Higgs factory, based on this world-class Strasbourg cluster of expertise, is a strategic move for CNRS Nuclei & Particles. Therefore there are numerous opportunities for young scientists to develop original and visible lines of research.

The recruited person will strengthen two teams involved for a long time in the design and construction of semiconductor-based trackers, which allowed to build at the laboratory a strategic expertise.

The CMS team of the IPHC is strongly implicated in the research of new physics as in the physics of the Higgs boson (notably via its coupling to tau leptons). To conduct these analyses, the group builds on its expertise in the construction of tracking detectors and the understanding of their performance: it contributed to the construction of the actual CMS detector, and is involved for the HL-LHC phase in the construction of a large part of the new tracker.

In close collaboration with the C4PI platform, the PICSEL/FCC team has been involved for more than 20 years in R&D, design and tests of CMOS pixel detectors. The latest prototypes are now close to fulfill the requirements for a future Higgs factory such as the FCC-ee project.

The scientific project is related to the precision measurements of the Higgs boson couplings and the search for physics beyond the Standard Model. Working with the CERN's LHC collider, during Run 3 and its high-luminosity phase, the candidate will have the opportunity to make major contributions to particle physics at IPHC and CNRS, drawing on the skills and expertise of the local CMS team. He or she will also play a leading role in the definition of a tracking and vertexing detector for a future collider, such as the FCC-ee project at CERN. To this end, the candidate will build on the world-leading expertise in CMOS pixel sensors and microtechnology available in the laboratory via the C4PI platform, and will lead, relying on concepts and simulations, a project to develop a high-performance, innovative detector capable of attracting a significant community at IPHC and at national level.

The successful candidate will be involved in existing teaching programs linked to the research theme at the host laboratory's university site. The teaching project will be discussed with the University of Strasbourg and clarified at a later date, in order to match the profile of the successful candidate.

The CNRS is developing a strong policy in favor of open science. Open science consists of making research results "as accessible as possible and closed as necessary". As such, the CNRS aims to make 100% of the texts of publications resulting from the work of its laboratories accessible , in particular through deposit in HAL. The data produced must also be made available and reusable, except for specific restrictions. In addition, the guiding principles of individual evaluation have been revised in accordance with the DORA declaration, to be more qualitative and to take into account all facets of the researcher's profession.

The dissemination of the results will be done through world-class scientific productions: publications, patents, software... In addition, the results will be communicated to various targets such as scientific communities, media, decision makers, general public, schools, etc., with an adapted calendar. Specific tools may be developed such as websites, newsletters, meetings, international symposia, summer schools and conferences.

The relationship between science and society is now recognized as a full dimension of scientific activity. The project will develop this dimension in synergy with all the partners. The resulting research work will contribute to informing public decision-making. Participatory science initiatives may be initiated with actors from the project's socio-economic and cultural eco-system.

holders of a doctorate or a PhD or equivalent degree or applicants who have gained scientific. There is no restriction on the age or nationality of applicants. All CNRS positions are accessible to people with disabilities, with special arrangements for tests made necessary by the nature of the disability.
