Experimental Neutrino Physics Group

The experimental neutrino physics group is involved in three experiments around the world, described below. Our research involves the study of fundamental subatomic particles called neutrinos.  In particular our current research focuses on the flavor oscillations of neutrinos using accelerator-generated neutrino beams.   We have active efforts on detector hardware and data analysis for these projects.

Prospective graduate students:  Please contact Profs. Marino and Zimmerman if you are interested in any of these projects.

Current Group Members:

  • Faculty: Alysia Marino and Eric D. Zimmerman
  • Postdocs: Jeremy Lopez and Yoshikazu Nagai
  • PhD Students: Scott Johnson and Brant Rumberger
  • Undergraduate Students: Nick Johnston and Max Weiner




The T2K experiment is a neutrino oscillation experiment in which neutrinos are produced at J-PARC and detected by the Super-Kamiokande detector, 295 km away in the Kamioka mine. In 2013, the T2K experiment discovered conclusive evidence for the appearance of electron neutrinos in a beam of muon neutrinos, indicating a non-zero value of θ13. The CU T2K group two faculty members Alysia Marino and Eric Zimmerman have led the effort to build several focusing horns for the neutrino beam and are involved in many areas of physics analysis for both the near and far detectors. Colorado hosts a T2K computing center.


The NA61/SHINE experiment is a large-acceptance fixed-target detector located at CERN. The detector allows researchers to make precise measurements of the production of hadrons from proton interactions that help us better understand the flux of neutrinos generated by protons in accelerator-generated neutrino beams such as those used for T2K and DUNE. The CU NA61/Shine group has two faculty members: Alysia Marino and Eric Zimmerman.


DUNE is a proposed long-baseline neutrino oscillation experiment that would involve a new neutrino beam from Fermilab to the Sanford Underground Research Facility (SURF) in the former Homestake gold mine in South Dakota. The CU DUNE group (led by Alysia Marino and Eric Zimmerman) is primarily focused on making in-situ and ex-situ measurements of the neutrino beam to improve predictions of the neutrino flux.
