In nuclear beta decay an up quark ‘u’ in a proton converts into an up down quark ‘d,’ turning the proton into a neutron and emitting a positron and a neutrino. This work affects ...

Particle-accelerator study focuses on the r-process thought to be responsible for forming elements heavier than iron ...

To achieve this, the AMoRE collaboration tried to observe neutrinoless double beta decay using molybdenum-100 (100 Mo), a radioactive isotope of molybdenum with an atomic number of 42 and a mass ...

The AMoRE experimental collaboration in South Korea has reported not finding evidence of neutrinoless double beta decay after a two-year search, imposing stringent limits on this mysterious, ...

Neutrinos, the mysterious and nearly massless particles that barely interact with anything, are revealing new secrets through the KATRIN experiment. Using tritium decay and advanced spectrometry, ...

Beta (\(\beta^-\)) decay is the release of an electron by the change of a neutron to a proton. The neutron (charge = 0) is made up of one up quark (charge = \(\frac{2}{3}\)) and two down quarks ...

The effects of the weak force were first discovered at the turn of the 20th century, in the place where it is most obviously at work: in radioactive beta decay. In the most common form of this ...

New data establish an upper limit of 0.45 eV/c2 (equivalent to 8 x 10-37 kilograms) for the neutrino mass. KATRIN measures neutrino mass in the laboratory using a model-independent method.

Here is the equation for the alpha decay of radon-219 into polonium. Beta decay involves the conversion of a down quark to an up quark. This changes a neutron into a proton plus an electron.

nEXO will search for neutrinoless double beta decay of xenon-136. Neutrinoless double beta decay experiments probe physics beyond the Standard Model by searching for an extremely rare nuclear decay.
