Postdoctoral researcher

For our location in Hamburgwe are seeking:

Postdoctoral Researcher ATLAS Experiment

Limited: 2 years | Start: | ID: FHPO008/2026 | Deadline: | Full-time/Part-time | Remote work possible

DESY, with more than 2900 employees at its two locations in Hamburg and Zeuthen, is one of the world's leading research centres. Its research focuses on decoding the structure and function of matter, from the smallest particles of the universe to the building blocks of life. In this way, DESY contributes to solving the major questions and urgent challenges facing science, society and industry. With its ultramodern research infrastructure, its interdisciplinary research platforms and its international networks, DESY offers a highly attractive working environment in the fields of science, technology and administration as well as for the education of highly qualified young scientists. The particle physics programme of DESY includes strong contributions to the LHC experiments at CERN and the preparation of future experiments. The experimental programme is enhanced by collaboration with a strong theory group. The DESY ATLAS group is involved in data analyses focusing on W and Z production, Higgs, top quark and Beyond Standard Model physics. In addition the group is involved in the operation of the ATLAS detector and developments for future upgrades, such as the ATLAS silicon strip tracker for the High Luminosity LHC. A new Emmy Noether group within the ATLAS group will be addressing limitations to the measurement of total Higgs boson decay rates by scrutinizing some of the foundational assumptions underlying these measurements and identifying areas where these assumptions can be reevaluated or relaxed. We are Hiring a postdoc to join the new Emmy Noether group and contribute to these measurements.

About your role:

• Higgs boson width determination using H->ZZ events
• Tests of the stability of the measurement with respect to various assumptions, specifically looking into the effect of several free parameters
• Perform EFT fits to constrain potential BSM effects
• Daily supervision of students working on these topics
• Contributing to the performance studies of ATLAS

Good reasons to join:

• Look forward to a unique working environment on our international research campus.
• Respectful cooperation and the well-being of our DESY employees are particularly important to us.
• Gender equality is an important aspect for us.
• To support work life balance we offer flexible working hours, variable part-time, job-sharing models and participation in mobile work (up to 50%).
• You will benefit from our family-friendly and collegial atmosphere, our established health management and occupational pension provision.
• As a public funded employer, we offer you a secure workplace and facilitate your individual career with our comprehensive training and development opportunities.
• Remuneration is according to the regulations of the TV-AVH.
• DESY offers its employees a financial supplement for a German job ticket (Deutschland-Ticket) at both locations.

About you:

• Experience in the analysis of big data
• Familiar with EFT frameworks (specifically event generation with EFT models)
• Familiar with statistical analysis tools
• Able to handle combinations of different particle physics measurements

DESY promotes equal opportunities, diversity and inclusion . We therefore welcome applications from people of all dimensions of diversity. The professional development of women is very important to us and therefore we strongly encourage women to apply for the vacant position. Applications from severely disabled persons and those with equivalent status will be given preference if they are equally qualified (sbv.desy.de).
