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 ...

All the latest science news on mesons from Phys.org. Find the latest news, advancements, and breakthroughs.

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 ...

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.

Quark recombination in the quark-gluon plasma formed in high-energy nuclei collisions enhances the production of Bc mesons. These mesons consist of a charm quark and a bottom quark. Most of the ...

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 ...

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 ...
