Amid the chaotic chains of events that ensue when protons smash together at the Large Hadron Collider in Europe, one particle has popped up that appears to go to pieces in a peculiar way. All eyes are ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

One of the most important observations in particle physics was the discovery in 1964 of the Omega-minus baryon at Brookhaven National Laboratory. In the two decades leading up to this point over 27 ...

Physicists at the Belle experiment at the KEK laboratory in Japan have discovered a new particle that provides the best evidence yet that some mesons contain four quarks rather than the usual two.

Pentaquarks do not fit into the traditional quark model of hadrons, but understanding these exotic new particles is offering fresh insights into the subtleties of the strong interaction Five quarks In ...

Theorists have performed calculations to predict the temperature at which bottomonium mesons will melt. Bottomonium mesons are particles made of one of the six types of quark: a heavy bottom quark ...

The new generation of atom smashers such as the Large Hadron Collider is offering hints that new physics (and exotic new particles) await discovery. And scientists are just reaching the point where ...
