Nuclear Science Division.Ernest Orlando Lawrence Berkeley National Laboratory, Berkeley, CA (United States)Berkeley, CaliforniaLawrence Berkeley National Laboratory2010-01-29engLeading and subleading twist transverse momentum dependent parton distribution functions (TMDs) are studied in a quark model framework provided by the bag model. A complete set of relations among different TMDs is derived, and the question is discussed how model-(in)dependent such relations are. A connection of the pretzelosity distribution and quark orbital angular momentum is derived. Numerical results are presented, and applications for phenomenology discussed. In particular, it is shown that in the valence-x region the bag model supports a Gaussian Ansatz for the transverse momentum dependence of TMDs.26Quark ModelTransverse MomentumQuarksDistribution FunctionsBag Model72 Physics Of Elementary Particles And FieldsOrbital Angular MomentumDistribution
