In a Physical Review Letters study, the HOLMES collaboration has achieved the most stringent upper bound on the effective electron neutrino mass ever obtained using a calorimetric approach, setting a ...

Physicists on the CMS experiment announce the most elaborate mass measurement of a particle that is notoriously difficult to study and has captivated the physics community for decades. After an ...

Deep in the heart of the matter, some numbers don't add up. For example, while protons and neutrons are made of quarks, nature's fundamental building blocks bound together by gluons, their masses are ...

Final results from a long-running U.S.-based experiment announced Tuesday show a tiny particle continues to act strangely — but that’s still good news for the laws of physics as we know them. “This ...

Neutrinos are known to have tiny masses. A new result proclaims the subatomic particles to be even tinier still. Neutrinos are the only class of fundamental particle for which the mass, one of the ...

Physicists have set a new upper limit on the mass of neutrinos. And the finding could poke a big hole in the Standard Model of particle physics. When you purchase through links on our site, we may ...

The power of science has the ability to educate, empower and entertain which is why this morning we were thrilled to welcome ...
