Latest results with the NEXT-White detector

Description

The NEXT Collaboration has been operating the NEXT-White detector at the Laboratorio Subterráneo de Canfranc (LSC, Spain) since 2016, and specifically with 136Xe-enriched gas since 2019. NEXT-White is a large-scale demonstrator for 136Xe neutrinoless double beta decay searches in a high-pressure xenon gas time projection chamber. The poster will present the latest NEXT-White results concerning:

• Demonstration of the 1% FWHM resolution in the region of interest for 136Xe double beta decay searches.
• Demonstration of the topological event identification capabilities.
• Measurement and understanding of radiogenic backgrounds.
• Measurement of the two-neutrino double beta decay half-life of 136Xe.
