We present a new determination of Transverse Momentum Dependent (TMD) parton distributions applying the Parton Branching method. The PB TMDs are obtained from fits to precision DIS data using DGLAP splitting functions at leading and higher order. In addition the CCFM splitting function will be applied to include small x effects.
Applications of these new TMD distributions will be discussed.
The PB TMDs were successfully used for obtaining predictions for LHC measurements. However, these measurements turned out to not be sensitive to some of the non-perturbative parameters existing in the PB approach. In this talk we show preliminary results for the application of PB TMDs to low energy DY data. We illustrate the role of non-perturbative dynamics, including intrinsic transverse...
In a SIDIS process, in order to establish the consistency of a particular hadronic observable with an estimate of the appropriate underlying partonic picture, one can introduce some quantitative criteria expressed in terms of various ratios of partonic and hadronic momentum degrees of freedom. I will describe how to use these criteria in phenomenology and provide a visualization of these...
