Oral contribution
We present a calculation of the effective cross section σ_eff , an important ingredient in the theoretical description
of double parton scattering in proton-proton collisions. The theoretical approach makes use of a Light-Front quark
model as framework to calculate the double parton distribution functions at low-resolution scale. QCD evolution is
implemented to reach the experimental...

In lightcone framework, longitudinal angular momentum operator is kinematical but the transverse angular momentum operator is dynamical and thus
understanding the transverse spin and transverse angular momentum of the proton is more complicated than longitudinal spin and angular momentum and frame dependent.
Here, we evaluate the gravitational form factors for a transversely polarized...

Oral contribution
The role of TMDs in understanding the 3D-structure of hadrons has drawn a lot of interest in both the theoretical and experimental communities. In order to extract TMDs, it is necessary to understand what information is contained in the different sets of data that are available. In this talk, I will discuss the advantages and limitations of some of the most recent experimental data, in the...

The Light-Front Wave Functions (LFWFs) represent a perfect starting point for describing the partonic structure of hadrons.
In this work we use the results for the LFWFs of the pion coming from the AdS/QCD correspondence, in the context of a soft-wall model. We study the parton distribution function (PDF) and the electromagnetic form factor (FF) of the pion and for the first time we implement...

Oral contribution
An approximate light-cone wave function for the pion effective quark-antiquark Fock sector corresponding to a small value of the renormalization group parameter $\lambda$ will be presented. This wave function will be used to obtain wave functions of higher pion sectors for larger $\lambda$ by the W-transformation [1].
The approximate wave function is motivated by the LF-holography [2] in...
