*Integrated and Unintegrated PDFs and GPDs From Effective**
**Two-Body Light-Cone Wave Functions*


We introduce a classification scheme for parton distribution models and we model
generalized parton distributions (GPDs), their form factors, and parton distribution
functions (PDFs), integrated and unintegrated ones, in terms of unintegrated double
distributions that are obtained from the parton number conserved overlap of effective
light-cone wave functions. For a so-called "spherical" model we present general
expressions for all twist-two related nonperturbative quantities in terms of one
effective light-cone wave function, including chiral-odd GPDs. We also discuss the
Regge improvement of such quark models from the $s$-channel point of view and study
the relations between zero-skewness GPDs and unintegrated PDFs on a more general ground.
