Open Positions

There currently is one open postdoctoral position and one open PhD position at the LPHE.

Postdoctoral research position in experimental particle physics (LHCb)

The High Energy Physics Laboratory [1] of EPFL, the Swiss Federal Institute of Technology in Lausanne, invites applications for a postdoc position to work on the LHCb experiment at CERN’s Large Hadron Collider. The lab is involved in diverse research activities with strong involvement in physics analysis of LHCb data and a major role in the construction and operation of the new Scintillating Fibre (SciFi) Tracker for the LHCb detector upgrade and the new PLUME luminosity monitor for LHCb. The group also actively pursues R&D of the SciFi detector technology for further upgrades of the LHCb tracker, other particle or astroparticle physics experiments, and medical applications.

The successful applicant is expected to be predominantly involved in data analysis within the LHCb collaboration, with emphasis on heavy flavour physics, and contribute to the operation of the LHCb detector. Depending on the candidate’s interest, a secondary involvement in detector R&D of the SciFi technology is also an option.

This full-time position will also involve PhD student supervision and teaching duties at the Bachelor or Master level. The position becomes available on January 1, 2024. The employment at EPFL [2] will be initially for one year, renewable up to a maximum of four years, pending funding availability.

Applicants must hold a PhD degree in experimental particle physics, obtained preferably within the past 5 years, or expect to graduate before the start of employment. They should prepare a single PDF file including the following documents: motivation letter, CV, and contact information of at least three references willing to write a recommendation letter. The file should reach our secretariat (Mrs Corinne Craman, [email protected]) by October 1, 2023. In addition, applicants should ask the references to send their letters to the same address by the same deadline.

PhD student position in experimental particle physics (LHCb)

The High Energy Physics Laboratory [1] of EPFL, the Swiss Federal Institute of Technology in Lausanne, invites applications for a PhD student position in experimental particle physics (LHCb experiment).

LHCb [2] is a flavour physics experiment running at the Large Hadron Collider at CERN, leader in the searches for physics beyond the Standard Model of particle physics. The successful candidate will be expected to perform data analysis under the supervision of Dr. Merli, investigating displaced vertex signatures with the Run3 dataset which LHCb is currently taking. Their PhD thesis will focus on the implementation of novel reconstruction techniques to test the existence of heavy neutral leptons, suggested by neutrino oscillations but never discovered so far.

The position, which also involves teaching duties at Bachelor or Master level, becomes available from February 1, 2024. The selected PhD student will need to enrol in the Physics program of the EPFL doctoral school [3], and the employment runs up to a total of four years. Doctoral school information and employment conditions at EPFL may be consulted online [3-5]. Applicants are expected to hold a Master degree (or equivalent) in Physics at the start of employment. The ideal candidate has a strong motivation for fundamental research, and has received education in Particle Physics. Experience with data analysis, computer programming and/or particle detectors is an advantage.

EPFL, as well as CERN, offers a stimulating multicultural working environment at the forefront of fundamental research. The position includes the possibility of frequent journeys between CERN and EPFL.

Applicants should prepare a motivation letter, CV, scans of the higher institution grade records, and contact information of three references willing to write a recommendation. The application should be submitted to the EPFL Doctoral Program in Physics (EDPY) following the instructions in [6] by the deadline of October 31, 2023. Please indicate Lesya Shchutska under Potential host laboratories and Particle physics under scientist interests. The references should be submitted by the referees by the same deadline following the request they receive.

More information can be obtained from Dr. A. Merli ([email protected]) and Prof. L. Shchutska ([email protected]).
