Predicting neutrino-nucleus quasielastic cross sections for next-generation oscillation experiments

01/27/2022 - 2:00pm to 3:00pm
Speaker(s) / Presenter(s): 
Bijaya Acharya (Oak Ridge | NTN Fellow)
Type of Event (for grouping events):
I will discuss our ongoing efforts aimed at constraining the systematic errors in long-baseline neutrino experiments through ab initio computations of neutrino-nucleus quasielastic scattering cross sections using a powerful quantum many-body method---the coupled-cluster theory---with nuclear forces and electroweak currents derived in chiral effective field theory ($\chi$EFT). After showing  precision results for the electroweak properties of the deuteron, which we use to benchmark our harmonic oscillator-basis representation of the $\chi$EFT electroweak currents, I will present recent results for some electron-scattering observables of $^4$He and $^{40}$Ca.
