Nucleon form factors and spin content in a quark-diquark model with a pion cloud

Cloet, Ian ChristopherMiller, Gerald A.2012-10-122012-10-122012Physical Review C, 2012; 86(1):0152080556-2813http://hdl.handle.net/2440/73545We propose a model of the nucleon in which quark-diquark configurations immersed in a pion cloud are treated in a manner consistent with Poincaré invariance. With suitably chosen parameters, the computations employing this model reproduce the measured electromagnetic form factors and the quark-spin contribution to the total nucleon angular momentum.en©2012 American Physical SocietyNucleon form factors and spin content in a quark-diquark model with a pion cloudJournal article002012100110.1103/PhysRevC.86.0152080003065089000042-s2.0-84864406303
