Galaxies, stars, planets and life, all are formed from one essential substance: matter. But the abundance of matter is one of the biggest unsolved mysteries of physics. The Big Bang, 13.8 billion ...

Neutrino mass measurements remain one of the most challenging endeavours in contemporary physics. Direct measurement techniques, particularly those probing the endpoint of the tritium β-decay spectrum ...

Transmuting one element into another (usually gold, of course) was the stuff of fevered dreams and fanciful imaginations for alchemists way back in the day. It turns out that nature does it all the ...

Double beta decay, one of the rarest nuclear processes, offers a unique portal into the fundamental properties of neutrinos and the conservation of lepton number. Experimental strategies have evolved ...

A group of scientists, among them several from GSI Helmholtzzentrum für Schwerionenforschung and from Technical University of Darmstadt, succeeded in experimentally determining the characteristics of ...

Neutrino-free process: observing neutrinoless double beta decay could shed light on important mysteries of particle physics. A new technique to enable the detection of a hypothetical process called ...

The MAJORANA DEMONSTRATOR is a proof-of-concept experiment. The researchers constructed an ultrasensitive 44-kilogram germanium radiation detector to seek the extremely rare nuclear process. Like a ...
