If new particles are out there, the Large Hadron Collider (LHC) is the ideal place to search for them. The theory of supersymmetry suggests that a whole new family of partner particles exists for each of the known fundamental ...
A group of theoretical physicists at Johannes Gutenberg University Mainz (JGU) has once again succeeded in significantly improving their calculations of the electric charge radius of the proton published in 2021. For the ...
The muon is a subatomic particle that resembles an electron but is 200 times heavier. It interacts with nuclei through the weak force, one of the four fundamental forces in the universe. When a muon binds with a deuteron ...
Binding together quarks into protons, neutrons and atomic nuclei is a force so strong, it's in the name. The strong force, which is carried by gluon particles, is the strongest of all fundamental forces of nature—the others ...
A team of international researchers, led by experts at the University of Adelaide, has uncovered further clues in the quest for insights into the nature of dark matter.
Neutrinos are tiny and neutrally charged particles accounted for by the Standard Model of particle physics. While they are estimated to be some of the most abundant particles in the universe, observing them has so far proved ...
An important recent discovery in physics came from measuring neutrinos—neutral, weakly interacting particles—produced by the sun. Nuclear reactions in the sun produce only electron neutrinos. According to the standard model, ...
The Muon g-2 collaboration has announced their much-anticipated updated measurement. The new result aligns with the collaboration's first result, announced in 2021—and it's twice as precise. In fact, it's the most precise ...
This week on phys.org, we published news about muons, gigantic stellar waves, a Homo-erectus-thwarting mini ice age, and a new whale guy.
Despite its tremendous success in predicting the existence of new particles and forces, the standard model of particle physics, designed over 50 years ago to explain the smallest building blocks of nature, isn't the complete ...
