Charm mesons can travel as a mixture of both its particle and antiparticle states (a phenomenon appropriately called "mixing"). Physicists have known that for over a decade, ...

The facility has ambitious goals to produce over 10 trillion eta mesons annually, with production rates exceeding 100 million particles per second. Hunting for hidden particles.

Applying a symmetry property of the strong force, the team set the upper limit on the photoproduction cross sections of a hybrid meson known as the spin-exotic π 1 (1600).. Exotic-hybrid mesons ...

Exotic mesons: The ins and outs of quantum chromodynamics Date: July 7, 2015 Source: DOE/Oak Ridge National Laboratory Summary: Quarks and antiquarks are the teeny, tiny building blocks with which ...

The measurement was made over six years and involved the observation of some 535 million B mesons, which decayed into lighter subatomic particles called K and π mesons. New physics “This difference ...

For instance, K-mesons are composed of a strange antiquark with a mass of around 100 MeV and an up or down quark with a mass of only a few megaelectronvolts. The substantial difference in quark masses ...

If hybrid mesons, which are identical to ordinary mesons in composition but quite different in behavior, are discovered, it would help us expand our understanding of the strong nuclear force.

But mesons are close to the innermost problem: how to turn mass wholly into energy. A few pounds of mesons (if obtainable) would release more energy than 10,000 atomic bombs.

Introduction. In recent experiments, it has M. been shown that charged mesons, brought to rest A in photographic emulsions, sometimes lead to the production of secondary mesons. We have now ...

Recently, LHCb independently confirmed that neutral B mesons indeed have a preferred internal configuration and showed that the extent of this favoritism depends on how the B mesons decay. In one ...

In August 2003, an experiment at the KEKB particle accelerator in Japan found hints of an unexpected particle: A composite of elementary building blocks called quarks, it contained not two quarks like ...
