An obscure theory of elementary particles proved to be key to China’s re-emergence as a scientific nation after the Cultural ...

The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

Physicists at Fermilab in Chicago have improved the measurement of a subatomic particle called the W boson. Their result won't just help physicists better understand exotic particles; it also narrows ...

The National Academies of Sciences, Engineering, and Medicine are private, nonprofit institutions that provide expert advice on some of the most pressing challenges facing the nation and world. Our ...

Physics has demonstrated that the everyday phenomena we experience are governed by universal principles applying at time and distance scales far beyond normal human experience. Physics has ...

In 2024, the T2K Collaboration started to collect new neutrino data following several upgrades to the experiment that included new types of detectors. One of these, called SuperFGD, has a mass of ...

A collaboration of hundreds of scientists have precisely measured the mass of the W boson, an elementary particle responsible for the weak nuclear force. The researchers found, to their surprise, that ...

Todd Pedlar has been a professor in the Physics Department since 2003. Some of his course topics include Classical Physics, Electricity and Magnetism, Quantum Mechanics, Nuclear and Particle Physics, ...

At the 40th ICHEP conference, the ATLAS and CMS experiments announced new results which show that the Higgs boson decays into two muons. The muon is a heavier copy of the electron, one of the ...

Quantum mechanics, developed in the 1920s, has had an enormous impact in explaining how matter works. The elementary particles that make up different forms of matter -- such as electrons, protons, ...
