The CDF Collaboration at Fermilab has confirmed that a subatomic particle called the Bs meson flips between matter and ...

A heavy particle with an unusual decay pattern discovered by the Belle experiment at KEK in Japan is the latest addition to the meson family tree The Belle detector If we had to name a modern-day ...

University of Melbourne physicists have helped discover a new state of matter that may shed light on the fabric of the universe. University of Melbourne physicists have helped discover a new state of ...

While nuclear physicists know the strong interaction is what holds together the particles at the heart of matter, we still have a lot to learn about this fundamental force. Results published earlier ...

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.

Calculations of charge distribution in mesons provide benchmark for experimental measurements and validate widely used 'factorization' method for imaging the building blocks of matter. Nuclear physics ...

More than three years after discovering a never-before-seen subatomic particle, physicists now know how these particles — called pentaquarks — are put together. New research reveals three completely ...

The most precise calculations yet of how two quarks locked in a bound state annihilate have been achieved using lattice quantum chromodynamics — and signal a curious discrepancy. Figure 1: CP ...
