Abstract

Abstract : The form factors of the exotic pentaquarks such as P c + ( 4450 ), P c + ( 4380 ), N c 0, Θ c 0, Ξ c 0 etc. have been investigated for the momentum transfers, Q 2 in the range of 0.01 < Q 2 < 1.0 GeV 2 . The wave function from the statistical model has been used to compute the form factors. The form factors are found to decrease sharply with the increase of Q 2 in the range of 0.01 < Q 2 < 0.1 GeV 2 which indicates the scaling violation with the gluon contribution to the form factor and the structure function whereas the form factors show gradual decrease with a small scaling violation in the range of 0.1 < Q 2 < 1.0 GeV 2 . The results have been compared with the other available theoretical and experimental data.
