ATLAS Experiment releases new search for long-lived particles

Despite its decades of predictive success, there are important phenomena left unexplained by the Standard Model of particle physics. Additional theories must exist that can fully describe the universe, even though definitive ...

Long-standing tension in the Standard Model addressed

The best-known particle in the lepton family is the electron, a key building block of matter and central to our understanding of electricity. But the electron is not an only child. It has two heavier siblings, the muon and ...

ALMA observes the formation sites of solar-system-like planets

Researchers have spotted the formation sites of planets around a young star resembling the sun. Two rings of dust around the star, at distances comparable to the asteroid belt and the orbit of Neptune in the solar system, ...

The hunt for leptoquarks is on

Matter is made of elementary particles, and the Standard Model of particle physics states that these particles occur in two families: leptons (such as electrons and neutrinos) and quarks (which make up protons and neutrons). ...
