Abstract
]]> The strangeness content of nucleon form factors is analyzed in a two–component model with a quark–like intrinsic structure surrounded by a meson cloud. A comparison with the available experimental data from the SAMPLE, PVA4, HAPPEX and G0 collaborations shows a good overall agreement for the strange form factors.Keywords: Strange form factors; vector meson dominance.
Resumen
Se analiza el contenido de extraneza de los factores de forma del nucleón en un modelo de dos componentes que consiste en una estructura intrínseca de tres cuarks constituyentes rodeada de una nube mesónica. Una comparación con los datos experimentales disponibles de las colaboraciones SAMPLE, PVA4, HAPPEX y G0 muestra un buen ajuste para los factores de forma con extrañeza.
Descriptores: Factores de forma extraños; dominancia de mesones vectoriales.
