Studies of TMDs with CLAS

Studies of single and double-spin asymmetries in pion electro-production in semi-inclusive deepinelastic scattering of 5.8 GeV polarized electrons from unpolarized and longitudinally polarized targets at the Thomas Jefferson National Accelerator Facility using CLAS will be discussed. We present a Bessel-weighting strategy to extract transverse-momentum-dependent parton distribution functions.
