A Global Analysis of Light and Charge Yields in Liquid Xenon

Lenardo, Brian, Kazkaz, Kareem, Manalaysay, Aaron et al.

Understand

We present an updated model of light and charge yields from nuclear recoils in liquid xenon with a simultaneously constrained parameter set.

A global analysis is performed using measurements of electron and photon yields compiled from all available historical data, as well as measurements of the ratio of the two.
These data sweep over energies from 1 - 300 keV and external applied electric fields from 0 - 4060 V/cm.
The model is constrained by constructing global cost functions and using a gradient descent minimizer, a simulated annealing algorithm, and a Markov Chain Monte Carlo approach to optimize and find confidence intervals on all free parameters in the model.
