Both positronium and mesons can exist even as their dimmers like the dipositronium and the mystery meson (X3872) respectively.
Here scientists found a particle named Bs meson, which decayed into two muons for the first time.
Other topics include systematics of mesons and baryons, baryon-baryon and baryon-antibaryon systems, and multi-particle production processes.
Now, some 37 years later, the Liverpool physicists and their colleagues have helped show that CP violation also exists in B Meson particles, proving it to be a general law of nature.
B-factories make a ''B'' version of a subatomic particle known as a meson.
Because of this difference, plus the need to circulate high currents in order to produce millions of B mesons, physicists have designed a machine with the two different kinds of particles traveling in two separate rings.
This is the first big step in our attempt to measure CP violation with B mesons and thereby understand why the universe contains so much more matter than antimatter," said Caltech physicist David Hitlin, the spokesman of the BaBar collaboration.
Their diagonal is the natural axis of the star symmetry, since under the interaction in the star the mesons keep moving along this axis.
Held together by particles called gluons, quarks and their antimatter counterparts, antiquarks, cluster in threes to form baryons (including protons and neutrons) and in pairs to produce mesons (including pions and kaons).
High, to be placed under laboratory mesons, with tray top and bottom flange to avoid falling objects with wheels.
CERN, the European Organization for Nuclear Research, announced in Switzerland this morning that researchers on two separate LHC experiments succeeded in measuring the decay of B-subscript-s mesons into two muons.
The first step is to map QCD to an effective theory expressed in terms of the important degrees of freedom of low energy QCD, mesons and nucleons.
