Although many fascinating experiments take place on ... in all three “flavors”—each contain a mass billions of times smaller than that of an electron. Even still, neutrinos and antineutrinos ...

What does increase dramatically is the energy (and the mass). At the beginning of an experiment, a beam of electrons may have a rest energy of 1/2 million electron volts; it is directed through a ...

A new underground facility called DUNE, which will accelerate particles for 800 miles between Illinois and South Dakota, ...

An electron has been turned into a spiralling wave of mass and charge ... depending on the experiment. In this one, the ...

When theorists try to predict the energy of an electron in some experiment, they don't have to calculate the effect of every conceivable particle in huge numbers, just those particles whose mass ...

He called it a neutron, and imagined it as a paired proton and electron ... particle -- one with the same mass as a proton, but with zero charge. His experiments were successful.

Despite its short lifetime, the experiment lay vital groundwork for ADONE: an electron-positron collider 105 meters in diameter that would go on to operate until 1993. This larger collider helped ...
