Job Description

The Pacific Northwest National Laboratory (PNNL) is seeking outstanding applicants for a postdoctoral position to participate in the Belle II experiment at the SuperKEKB collider in Tsukuba, Japan. The collaboration is currently commissioning the detector after extensive upgrades, with first collisions expected in March 2018. The main goals of the experiment are to study CP violation and to search for new phenomena in rare decays. An integrated luminosity of 4-10 ab-1 is anticipated to be collected in the first 2-3 years of operation, representing a significant increase in data over the previous generation of B-factory experiments and competitive with the physics reach of the LHCb experiment in many cases.

The PNNL group has played leading roles in the development of the imaging time-of-propagation detector and physics studies of early data. We currently have responsibilities in the DAQ development and commissioning of the barrel charged particle ID system. Our physics focus is precision measurements in electroweak penguin transitions in B-meson decays from data collected at the Upsilon(4S). Our physics interest also includes studies of quarkonium and exotic QCD as well as searches for dark matter with data that may be taken at the Upsilon(6S) resonance during early data taking. The successful candidate will be expected to take a leading role in physics analysis aligned with these efforts, with results of their research to be presented at collaboration meetings and international conferences, and published in peer-reviewed scientific journals.

We seek self-motivated applicants with excellent communication and technical skills. Candidates must have a strong background in data analysis. Experience with C++ and Python programming is mandatory. A solid publication record is desired. Extended stays in Japan may be required.

The PNNL Belle II group works closely with other groups on neutrino and low-background physics including Project 8, nEXO, ADMX, and SuperCDMS. Synergistic activities with these or other PNNL groups engaged in national security, detector development, and other Laboratory priorities are welcome.

The principal responsibilities of the chosen researcher are to work constructively with colleagues in the international research community. The post-doctoral fellow will be mentored by one of the senior researchers within the RDNS group. It is expected that the successful candidate will share responsibilities for the mentoring of summer students.

The position requires domestic and international travel, and activities outside normal working hours. The position is based on the PNNL Richland Campus, but frequent travel to Japan should be expected.

Please contact for further details about the position.


Minimum Qualifications

Candidates must have received a PhD within the past five years (60 months) or within the next 8 months from an accredited college or university.


Preferred Qualifications

• Technical Expertise: Experience in HEP data analysis, C++, Python required.

• Level of Responsibility: Personal contributor to experimental analysis, and publication of results.

• Breadth of Relevant Technical Knowledge: Collider-based Particle Physics

Preferred Education - Ph.D. in particle physics.
