Dr. Schuster is a theoretical physicist and chair of the Particle Physics & Astrophysics department at Stanford’s SLAC National Accelerator Laboratory.
Schuster's research is focused on the underpinnings of the Standard Model, identifying dark matter and its properties, and developing concepts for new experimental tests of physics beyond the Standard Model. He has worked on LHC collider physics and methods of characterizing data, new models of weak-scale physics and dark matter, theoretical aspects of long-range forces and scattering amplitudes, and is directly involved in several experimental efforts as co-spokesperson for APEX, a founding member and physics coordinator for LDMX, and as a founding member of HPS.
Schuster's most recent theoretical and experimental work aims to explore the idea that dark matter is part of a broader dark sector of particles and interactions that can be discovered with small-scale laboratory experiments, some of which can be performed at SLAC.

Search for a New Gauge Boson in Electron-Nucleus Fixed-Target Scattering by the APEX Experiment
PHYSICAL REVIEW LETTERS
2011; 107 (19)
We present a search at the Jefferson Laboratory for new forces mediated by sub-GeV vector bosons with weak coupling α' to electrons. Such a particle A' can be produced in electron-nucleus fixed-target scattering and then decay to an e + e- pair, producing a narrow resonance in the QED trident spectrum. Using APEX test run data, we searched in the mass range 175-250 MeV, found no evidence for an A'→ e+ e- reaction, and set an upper limit of α'/α ~/= 10(-6). Our findings demonstrate that fixed-target searches can explore a new, wide, and important range of masses and couplings for sub-GeV forces.
