Xi-cc++ was identified by the particles it decayed into - another baryon and three mesons.
Yet while we are indeed moving forward in time, there is also always some movement backwards, a kind of jiggling effect, and it is this movement I want to measure using these K and B mesons.
It seems that the super-conducting magnet (two opposing factors) somehow polarizes the electron, probably through some new kind of unifying electo-magneton coupling interaction, forming the end-to-end linear chain of the polarized electrons within the magnet, turning them into particles like the neutrinos, or mesons or even photons with the unbalanced opposite polarity emerging at the two ends of the magnet
Here scientists found a particle named Bs meson, which decayed into two muons for the first time.
El meson Bc tiene como caracteristica principal el hecho de estar conformado por dos quarks pesados con diferente sabor: el b y el c, razon por la cual es considerado heavy quarkonia, al igual que los estados c[barra.
Two mesons remain in a coherent p-wave state until one of them decays.
Other topics include systematics of mesons and baryons, baryon-baryon and baryon-antibaryon systems, and multi-particle production processes.
There are two unambiguous pieces of evidence for CP- and I-violation: the forbidden decay modes of neutral K and B mesons and the excess of the baryonic matter over antimatter in the present universe.
A Monte Carlo simulation was produced to better understand CLAS's backward angle detection of K mesons produced from the phi meson photoproduction process.
This particular zone, known as the "B-Factory," is a 1,200 ton particle detector used in scientific experiments studying distinctions between the decays of sub-atomic B mesons and their anti-matter counterparts, which may in turn explain why the universe favored the existence of matter over anti-matter following the Big Bang.
During experiments conducted between June last year and July this year, the physicists found evidence suggesting that anti-B mesons decay earlier than B mesons, which would lend weight to the theory that particles and antiparticles are not completely symmetrical, the researchers say.
Sited at the Fermi National Accelerator Laboratory in Illinois, the so-called KTeV experiment generates short-lived particles called neutral K mesons, or kaons.
