The standard model (SM) of particle physics is the mathematical description of the fundamental constituents and interactions of matter. Its last missing particle, the Higgs boson, was observed in 2012 ...

If you want to explain what was and what is, you need particle physics. Because everything we see consists of molecules and atoms, and atoms in turn consist of atomic nuclei and electrons. The atomic ...

CERN’s calculation of the W boson’s mass agrees with theory, contradicting a previous anomaly that had raised the possibility of new physics. Particle’s surprise mass threatens to upend the standard ...

An international team of researchers has systematically measured the β-decay half-lives of 40 nuclei near calcium-54, providing key experimental data for understanding the structure of extremely ...

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 ...
