Dark matter makes up more of our universe than ordinary matter ESA/Euclid/Euclid Consortium/NASA, image processing by M. Schirmer (MPIA, Heidelberg) A centuries-old experiment could help accelerate the search for new and exotic particles, including those that make up dark matter. In 1773, British scientist Henry Cavendish set up a simple experiment aimed at uncovering the…
Particle collisions inside the STAR detector at the Solenoidal Tracker at RHIC, known as STAR Brookhaven National Laboratory A pair of rare particles produced in high-energy proton collisions may be the clearest evidence yet that mass can emerge from empty space. The finding could shed light on one of the biggest puzzles in physics: how…
The LHCb experiment cavern at CERN CERN/Brice, Maximilien A new particle has popped into existence at CERN’s Large Hadron Collider, a heavier proton-like particle that contains two charm quarks. Protons and neutrons are examples of a class of particles called baryons, which each contain three fundamental subatomic particles called quarks that come in a variety…
