AUTHOR=Gomez-Cadenas Juan J., Monrabal Capilla Francesc, Ferrario Paola TITLE=High Pressure Gas Xenon TPCs for Double Beta Decay Searches JOURNAL=Frontiers in Physics VOLUME=7 YEAR=2019 URL=https://www.frontiersin.org/articles/10.3389/fphy.2019.00051 DOI=10.3389/fphy.2019.00051 ISSN=2296-424X ABSTRACT=This article reviews the application of high pressure gaseous xenon time projection chambers to neutrinoless double beta decay experiments. First, the fundamentals of the technology and the historical development of the field are discussed. Then, the state of the art is presented, including the prospects for the next generation of experiments with masses in the ton scale range.
