Baryons are subatomic particles made up of an odd number of quarks. Protons and neutrons found at the center of atoms are a ...

The decay process involves two neutrons simultaneously decaying into two protons, emitting two electrons and two antineutrinos. If the neutrino is a Majorana particle – its own antiparticle – then the ...

In beta decay, an unstable atom releases energy in the form of a particle (called a beta particle). Scientists studying beta decay found that the energy of the beta particle was not enough to account ...

In the EXO-200 experiment, physicists monitor a copper cylinder filled with 200 kilograms of liquid xenon-136, an unstable isotope that, theoretically, can undergo neutrinoless double beta decay.

To understand the importance of neutrinoless double-beta decay, we have to go back more than a century, to the late 1800s, to understand what radioactive decay is in the first place.

Researchers have observed a rare nuclear decay. Namely, the team measured low-kinetic-energy protons emitted after the beta decay of a neutron-rich nucleus beryllium-11.

If the double-beta decay isn't symmetrical, that means that neutrinos and antineutrinos behave differently. This isn't true of other kinds of particle-antiparticle pairs, as far as anyone knows.

The decay is known as a “golden channel” because its rate can be predicted to high precision by the standard model. The experiment, called NA62, aims to test that precise prediction.
