The structure of generalized parton distributions is determined from light-front holographic QCD up to a universal reparametrization function $w(x)$ which incorporates Regge behavior at small $x$ and inclusive counting rules at $x \to 1$. A simple ansatz for $w(x)$ which fulfills these physics constraints with a single-parameter results in precise descriptions of both the nucleon and the pion...

The structure of the hadronic matrix elements of the energy-momentum tensor play an important role in determining the properties of the corresponding form factors which appear in the Lorentz covariant decomposition of these objects. In this talk I will discuss a non-perturbative approach to constraining the low energy limit of these form factors, and its relevance in interpreting the vanishing...

The ridge effect observed in high multiplicity events in proton-proton scattering at LHC can be due to the collisions of flux tubes in the projectiles which are in turn related to the fundamental physics of color confinement. We discuss observable effects due to gluon string collisions in electron-proton and peripheral proton-proton scattering related to scattering of photons. In the former...
32. Single-Transverse-Spin-Asymmetry Studies in the Fixed-Target Mode using the LHC Beams (AFTER@LHC)

I will review the physics opportunities offered by the use of the multi-TeV proton LHC beam in the fixed-target mode with a polarised target.

We evaluate the gluon and charm parton distribution functions (PDFs) of the deuteron using light-front quantization together with the impulse approximation. We use a nuclear wave function obtained by solving the nonrelativistic Schrödinger equation with the realistic Argonne v18 nuclear force; it is then convoluted with the proton PDF. The resulting gluon distribution in the deuteron (per...
