The Physics Department at the University of Massachusetts Amherst invites applications for up to three (3)Postdoctoral Research Associate positions. The successful candidates would primarily work on experimental nuclear physics research on one or more of the following projects: UMass plays a leading role in the MOLLER experiment at Jefferson Lab, now in the engineering design and construction phase, and poised to make the world’s most precise measurement of a low energy purely leptonic weak neutral current process. Ongoing activities focus on engineering design support, simulations, prototype testing, and software and analysis infrastructure for installation and commissioning. Synergistic R&D on the P2 experiment at Mainz, the SOLID proposal at JLab and future high
