In 1930, a young physicist named Carl D. Anderson was tasked by his mentor with measuring the energies of cosmic rays—particles arriving at high speed from outer space. Anderson built an improved ...

Two independent lines of evidence from the world’s most powerful particle experiments are converging on the same uncomfortable conclusion: something is producing signals that the Standard Model of ...

Scientists working at CERN’s Large Hadron Collider may be seeing the strongest hints yet of physics beyond the Standard Model — the decades-old theory that explains the fundamental particles and ...

How did the universe come into being? There are a multitude of theories on this subject. In a Physical Review Letters paper, three scientists formulate a new model: according to this, inflation, the ...

A tiny discrepancy in particle physics has loomed for decades as an exciting possible crack in one of science's most successful theories, hinting at unknown forces or quantum objects. Now, an ...

If photons possess more quantum states than expected, it would overhaul our understanding of all particle physics – and now physicists have identified a way to test this radical idea in an experiment.

The mystery centered on the muon, a short lived particle that resembles an electron but is about 200 times heavier. For more than 60 years, measurements of the muon's magnetic behavior appeared to ...

Notoriously ghostly particles called neutrinos may have revealed a crack in our understanding of all the particles and forces in the universe. The standard model of particle physics, which catalogues ...

A proposed funding program for small- and medium-scale projects reveals insights into the science, logistical challenges, and future of particle physics research. Particle physicists have a reputation ...

Physicists have spent the last 20 years pondering an apparent discrepancy between experimental results and theoretical predictions for the magnetic properties of the muon, the electron’s heavier ...

Researchers at the Max Planck Institute for Quantum Optics (MPQ), Garching, in collaboration with Prof. Dr. Randolf Pohl from the Institute for Physics at Johannes Gutenberg University Mainz (JGU), ...
