INPP Seminar | Nov. 29

The Institute of Nuclear and Particle Physics Seminar series presents Amy Lovell discussing "Uncertainty quantification for Fission Modeling" on Nov. 29 at 4 p.m. in Lindley Hall 321.

Lovell is from Los Alamos National Laboratory.

In-person seminars will be in Lindley 321. For remote seminars, connection info for the video conference (TEAMS or ZOOM) and abstract of the talk will be communicated by email before the seminar. The emails are sent to the inpp-seminar mailing list. To be added to this mailing list, contact Prakash .

The host is Charlotte Elster.

Abstract: A significant amount of research has gone into developing and improving uncertainty quantification methods for nuclear theory, particularly in moving beyond chi-squared calculations and covariance propagation, quantifying truncation and model errors, and developing emulators to apply these improved methods to computationally demanding calculations. Fission modeling presents a variety of challenges for uncertainty quantification, based on the time scales of the process, the computational cost of the modeling, and the large amount of information – mostly on exotic, neutron-rich nuclei – needed for calculations. In this talk, I’ll discuss some of our efforts at Los Alamos to consistently model the emission of neutrons and gamma rays from excited fission fragments and a new project aimed at improving the optimization and uncertainty quantification of the variety of correlated observables that are generated in fission events.
