Ciro Riccio

I am an Assistant Professor in the Department of Physics and Astronomy at Stony Brook University, where I am a member of the Neutrino and Nucleon decay (NN) group.

I received my Ph.D. in January 2018 with a thesis entitled “Measurement of the antineutrino flux and cross section at the near detector of the T2K experiment,” carried out under a joint doctoral agreement between the Università degli Studi di Napoli Federico II in Italy and Université Paris-Saclay, Commissariat à l'énergie atomique et aux énergies alternatives (CEA) in France.

From 2018 to 2020 I was a Postdoctoral Associate at the Università degli Studi di Napoli Federico II. In May 2020 I joined the NN group at Stony Brook University as a Postdoctoral Associate, and I subsequently joined the faculty.

My research interests focus on understanding the matter–antimatter asymmetry in the Universe: neutrino oscillations, neutrino–nucleus cross sections, statistical data analysis, and new detection technologies.

Neutrino oscillations are supported today by a very large set of measurements obtained with a variety of experimental configurations and techniques. These results can be interpreted in the framework of three active massive neutrinos, whose mass and flavor eigenstates are related by the Pontecorvo–Maki–Nakagawa–Sakata (PMNS) matrix, parameterized by three mixing angles and a CP-violating phase, together with the squared-mass differences of the mass eigenstates.

Three pieces of the puzzle nonetheless remain: the precise value of one mixing angle, the neutrino mass ordering, and the measurement of the CP-violating phase, which can shed light on the matter–antimatter asymmetry in the Universe.

Long-baseline experiments will make a noteworthy contribution to these measurements over the next two decades. Future experiments will achieve unprecedented precision, driven both by the substantial volume of data they will collect and by innovative detector technologies. This will allow us to test — and eventually go beyond — the PMNS paradigm.

I welcome inquiries from prospective graduate students, undergraduates seeking research experience, and postdoctoral candidates interested in experimental neutrino physics.

Projects in the group span the full arc of a activities in a multipurpose experiement like T2K and DUNE: oscillation and cross-section analysis, development of statistical fitting frameworks, detector commissioning, characterization, and hardware R&D for future detectors.

Undergraduate students at Stony Brook interested in a research project are encouraged to write with a short note about their background and interests. Prospective graduate students should apply through the departmental admissions process and are welcome to contact me directly beforehand.
