Researchers have made the first experimental determination of the weak charge of the proton. The results also include the determinations of the weak charge of the neutron, and of the up quark and down ...

Using the first new method in half a century for measuring the size of the proton via electron scattering, scientists have produced a new value for the proton's radius in a new experiment. Using the ...

Measuring up: an electron scattering experiment yields a small proton radius. (Courtesy: Jefferson Lab) For nearly a decade the size of the particle that makes up the bulk of the universe’s visible ...

An international team of researchers at the US Department of Energy's Jefferson Accelerator Laboratory in Virginia has measured the weak charge of the proton for the first time. Although first ...

Nothing is more emblematic of an electron than its negative charge. It’s the trait that determines how the particle behaves in electromagnetic environments, such as a wire’s electric field and Earth’s ...

Researchers from the Institute for Bioengineering of Catalonia (IBEC) and CIBER-BBN, in collaboration with teams from the ...

Chemists reveal method for differentiating PCET mechanisms – a key step for steering fundamental energy conversion and redox catalysis processes. Redox reactions form the basis of many fundamental ...
