Position description

The experimental high energy physics group at the University of California, Davis invites applications for a postdoctoral research position in experimental particle physics on the CMS experiment and the dedicated milliQan detector for millicharged particles at CERN. The CMS group at UC Davis comprises five faculty (Profs. Chertok, Citron, Conway, Erbacher, Mulhearn), one senior researcher, and a number of postdoctoral researchers and graduate students. Prof Citron also works on the milliQan detector.

The successful candidate will work under the supervision of Prof. Citron and is expected to play a leading role in searches for BSM long-lived particle (LLP) signatures as well as the HL-LHC Level 1 trigger upgrade at CMS. Prof. Citron’s LLP search efforts make use of both non-standard reconstruction as well as the application of sophisticated machine learning techniques. In addition, there will be opportunities to contribute to searches for millicharged particles with milliQan and be involved in the design and construction of proposed future dedicated detectors, such as those at the proposed Forward Physics Facility at the LHC.

A Ph.D. in experimental high energy physics at the time of appointment is required. There is flexibility for the position to be based at UC Davis or at CERN. The appointment is initially for two years and renewable annually, subject to mutual satisfaction.

The position is open immediately and will remain open until filled. Interested candidates can apply by sending a cover letter, curriculum vitae, and statement of research interests and experience, all in PDF format, and arrange to have at least three letters of reference sent to the Department of Physics & Astronomy CMS Group at
