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 ...

IN Nature of January 29, 1949 (p. 181), Prof. L. Jánossy and C. B. A. McCusker presented evidence for the existence of light mesons called 'λ-mesons' in the air showers of cosmic rays, and ...

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, ...

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 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.

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.

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 ...

Mesons measure collision temperatures. 13 Dec 2012 Tushna Commissariat. Decaying upsilon particles. A new method to accurately work out the temperature of a quark–gluon plasma has been developed by ...

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.

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 ...

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 ...
