IUPAP C11 Early Career Scientist Prize – Nominations for 2026

The Commission on Particles and Fields (C11) of IUPAP solicits nominations of outstanding young experimental or theoretical particle physicists for the two 2026 Early Career Scientist Prizes.

The prizes, each consisting of an IUPAP medal and a cash (CHF1000) award, will be presented at the 43rd International Conference on High Energy Physics, Natal, Brazil, on July 30th - August 5th, 2026.

Candidates for the prize should have a maximum of 8 years of research experience (excluding career interruptions) following the PhD.

Nominations for the IUPAP Particles and Fields Early Career Scientist Prizes:

can be made by experimental or theoretical particle physicists who know the work of the nominee well and include a citation statement.
should consist of a minimum of two and a maximum of three letters explaining the nominee's qualifications and scientific achievements, a complete CV, and a list of publications. In addition, if the nominee is a member of a large international experiment with a long list of publications signed by all or a large part of the collaboration, a list of up to 20 papers that demonstrate the work the candidate has done either as a leader or strong participant should be provided.
must include a proposed award citation of 50 words or fewer describing the contributions of the nominee.

Recipients of IUPAP Awards are expected to meet the commonly held standards of professional ethics and scientific integrity. Nominators should include a statement saying that, to the best of their knowledge, there are no concerns that IUPAP should be aware of regarding the nominee satisfying this expectation.

The nominator should collect the material and upload it at https://iupap-ecsp.desy.de/. All material should be submitted before February 1st, 2026, at 12:00 PM CET.

Marcelo Munhoz (chair) for IUPAP C11 (2025-2027).
