FORNL, meeting of Tuesday, September 14, How Did the Big Bang Create Matter?
Dr. Vince Cianciolo

How Did the Big Bang Create Matter?

Is the neutron round? If not, so what?

Matter should not exist – according to the laws of physics as we currently understand them – empirical evidence very much to the contrary. The secret to understanding this paradox may be revealed by high-precision measurements of the neutron's shape, quantified by its electric dipole moment (EDM).

Steadily improving measurements of the neutron’s EDM have been made over the last seventy years. For decades, world record neutron EDM measurements were carried out at ORNL thanks to our powerful neutron sources. The Spallation Neutron Source (SNS) provides an opportunity reclaim that record and perhaps prove that the neutron is not round and explain why matter exists.

In this talk Dr. Cianciolo will provide a high-level overview of why the existence of matter is an ongoing mystery and the relationship of this mystery to the shape of the neutron. I will also describe an experiment, under development at the SNS, that aims to improve the neutron EDM measurement precision by nearly two orders of magnitude.

ORNL Physics Division

Fundamental Nuclear and Particle Physics Section

Vince Cianciolo was born and raised in the suburbs of Detroit and received a BS in Physics from the University of Michigan and a PhD in Physics from MIT. Vince has worked in the ORNL Physics Division since 1997, initially working with Frank Plasil, Glenn Young and Soren Sorensen on the PHENIX experiment at the Relativistic Heavy Ion Collider. For the last decade, his work has focused on the development of an experiment to measure the neutron's electric dipole moment (nEDM) - its shape - at the Spallation Neutron Source (SNS). He is currently the co-spokesperson for this experiment

His outside interests include keeping up with his wife and kids, construction work for Habitat for Humanity, hiking, and craft beer (these days drinking more than brewing).
