Description
While the microphysics of Xenon in dual-phase TPCs is generally well understood, fully characterising the behaviour of nuclear recoils at very small (keV-scale) energies presents a series of challenges that contribute to many uncertainties in this regime. Thanks to its unique ability to calibrate in-situ using low energy deuterium-deuterium (DD) reflector neutrons, LUX-ZEPLIN is well positioned to provide valuable insight to our models. In this talk, I will present on the development of data quality cuts applicable to these datasets. Furthermore, I will demonstrate how this data can be used in a new procedure to constrain microphysical parameters such as the mean charge yield and its fluctuations.
