About The Artwork

For more information of this piece , please enter here : http://issuu.com/rafaelmago/docs/cromodin__mica_peque__o In theoretical physics, quantum chromodynamics (QCD) is a theory of strong interactions, a fundamental force describing the interactions between quarks and gluons which make up hadrons such as the proton, neutron and pion. QCD is a type of quantum field theory called a non-abelian gauge theory with symmetry group SU(3). The QCD analog of electric charge is a property called 'color'. Gluons are the force carrier of the theory, like photons are for the electromagnetic force quantum electrodynamics. The theory is an important part of the Standard Model of particle physics. A huge body of experimental evidence for QCD has been gathered over the years. A quark and an antiquark (red color) are glued together (green color) to form a meson (result of a lattice QCD simulation by M. Cardoso et al).The three kinds of charge in QCD (as opposed to one in quantum electrodynamics or QED) are usually referred to as "color charge" by loose analogy to the three kinds of color (red, green and blue) perceived by humans. Other than this nomenclature, the quantum parameter "color" is completely unrelated to the everyday, familiar phenomenon of color. Quarks are massive spin-1/2 fermions which carry a color charge whose gauging is the content of QCD. Quarks are represented by Dirac fields in the fundamental representation 3 of the gauge group SU(3). They also carry electric charge (either -1/3 or 2/3) and participate in weak interactions as part of weak isospin doublets. They carry global quantum numbers including the baryon number, which is 1/3 for each quark, hypercharge and one of the flavor quantum numbers. _________________________________________________________________ La cromodinámica cuántica (o llamada QCD) es una teoría cuántica de campos y su comportamiento de particulas que describe una de las fuerzas fundamentales : la interacción fuerte que intenta entender la estructura de los bariones (colectivos de tres quarks, como protones y neutrones) y mesones (pares quark-antiquark, como los piones) la carga de los quarks, partículas básicas dentro de esta teoría, se designa como carga de color; aunque no está relacionada con la percepción visual del color. El lagrangiano (evolución escalar de la temporalidad de un fenómeno) de la cromodinámica cuántica posee una simetría SU(3)c en la parte dependiente de los campos leptónicos (no experimenta interacción fuerte). Eso implica por el teorema de Noether que existen magnitudes conservadas asociada a esa simetría. La magnitud conservada es lo que llamamos "color". Las tres variedades de color se designan normalmente como R (red), B (blue) y G (green) (aunque estos nombres no tienen nada que ver con el color visual, que es un fenómeno electromagnético asociado a diferentes longitudes de onda). El confinamiento de la carga de color se produce por el hecho de que los gluones (aterimiento) a su vez pueden interaccionar entre ellos según su carga de color. Esto contrasta con la situación de los fotones del campo electromagnético que como están desprovistos de carga no interaccionan entre ellos. Esa diferencia crucial hace que la interacción electromagnética tenga un alcance potencialmente infinito frente al muy corto alcance de la interacción fuerte.
