Scientists have gained insights into the weak nuclear force from new, more sensitive studies of the beta decays of the 'mirror' nuclei lithium-8 and boron-8. The weak nuclear force drives the process ...
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 interpretation of beta ...
Electromagnetism and the weak nuclear force are two distinct fundamental forces. That wasn’t always the case. How many fundamental forces are there in our universe? For particle physicists, answering ...
Left: “Mirror” nuclei lithium-8 and boron-8 undergo beta decay, then split into two alpha particles. Right: Radioactive ions from the ATLAS accelerator at Argonne National Laboratory are suspended in ...
The Standard Model of Particle Physics is scientists' best understanding of the forces that describe how subatomic particles interact. The Standard Model encompasses four forces: the strong nuclear ...
