Quarks Gone Rogue: Flavor Symmetry Break Sparks Physics Shake-Up at CERN

In high-energy collisions between argon and scandium atomic nuclei, scientists from the international NA61/SHINE experiment have uncovered a striking anomaly. It points to a possible breakdown of one of the most fundamental principles in particle physics: the near-symmetry between up and down quarks, known as flavor symmetry. This unexpected result could reveal gaps in our [...]
