Probing spin-1 diquarks in deep inelastic structure functions
1983 (English)In: Zeitschrift für Physik C Particles and Fields, ISSN 0170-9739, E-ISSN 1431-5858, Vol. 19, no 1, p. 53-55Article in journal (Refereed) Published
Abstract [en]

Within the scope of a new diquark model for deep inelastic structure functions presented by us recently we use the existing data onF 1 ep (x,Q2) to learn about the admixture of spin-1 diquarks in nucleons. It turns out that they are so rare, heavy and extended compared to spin-0 diquarks that they are presumably accidental and not dynamical. Their number and form factors can be understood qualitatively within this picture. Still, the spin-1 diquarks give interesting structures in data and, together with quarks and spin-0 diquarks, carry enough momentum to account for the full nucleon energy. A gluon component is hence not needed in the nucleon!
