  • Description: <jats:title>A<jats:sc>bstract</jats:sc> </jats:title> <jats:p>Excellent energy resolution is one of the primary advantages of electroluminescent high-pressure xenon TPCs. These detectors are promising tools in searching for rare physics events, such as neutrinoless double-beta decay (<jats:italic>ββ</jats:italic>0<jats:italic>ν</jats:italic>), which require precise energy measurements. Using the NEXT-White detector, developed by the NEXT (Neutrino Experiment with a Xenon TPC) collaboration, we show for the first time that an energy resolution of 1% FWHM can be achieved at 2.6 MeV, establishing the present technology as the one with the best energy resolution of all xenon detectors for <jats:italic>ββ</jats:italic>0<jats:italic>ν</jats:italic> searches.</jats:p>
