Recent progress toward a definitive neutrino-less double beta decay search with a xenon gas time projection chamber—the NEXT experimental program
Presented by Prof. David Nygren (UT Arlington)
As the search for 0νββ in any isotope moves toward the ton-scale of active mass, background reduction/discrimination remains paramount but increasingly daunting. The use of gas-phase xenon offers both the use of event topology and the prospect of detecting the daughter barium ion, two powerful methods for discrimination against the most dangerous backgrounds due to gamma-ray conversions with energy near the decay Q-value in 136Xe of 2458 KeV. I will review recent progress along these two directions in our group at the University of Texas at Arlington and elsewhere. The future appears quite promising.
