The CMS and ATLAS experiments at the Large Hadron Collider joined forces to make the most precise measurement of the mass of the Higgs boson yet. On the dawn of the Large Hadron Collider restart, the ...

Physicists are exploring whether hidden dimensions and the shape of space could help explain why fundamental particles have ...

An experiment nearly two decades in the making has finally unveiled its measurements of the mass of the universe’s most abundant matter particle: the neutrino. The neutrino could be the weirdest ...

Neutrino mass measurements remain one of the most challenging endeavours in contemporary physics. Direct measurement techniques, particularly those probing the endpoint of the tritium β-decay spectrum ...

Physicists have spent decades treating mass as something the universe simply hands to particles, a property encoded in ...

For decades scientists have tried to find a way to measure the mass of the lightest matter particle known to exist. Three new approaches now have a chance to succeed. In 1980, Hamish Robertson was a ...

Negative mass is a hypothetical concept that says matter can exist with a mass opposite to normal matter. Instead of having a positive weight—1kg, for example—negative mass would weigh minus 1kg. This ...

NEWPORT NEWS, VA – Nuclear physicists may have finally pinpointed where in the proton a large fraction of its mass resides. A recent experiment carried out at the U.S. Department of Energy’s Thomas ...
