Abstract
The orbital angular momentum () of the proton is studied by employing the extended constituent quark model. Contributions from different flavors, namely, up, down, strange, and charm quarks in the proton are investigated. Probabilities of the intrinsic pairs are calculated using a transition operator to fit the sea flavor asymmetry of the proton [1]. Our numerical results lead to , in agreement with , and consistent with findings based on various other approaches.
