## "Momentum-space structure of hadrons and nuclei at high energy"

#### Presented by Elena Petreska, NIKHEF

Transverse-momentum-dependent (TMD) distributions describe the configuration of quarks and gluons inside protons and nuclei in three-dimensional momentum space.

Observables in scattering experiments can be calculated with the help of TMD factorization formulas, where the target and projectile are represented with non-perturbative TMD distributions, which are separated from the short-distance perturbative part of the collision.

A complementary approach to study the momentum structure of protons and nuclei at high energy is the Color Glass Condensate which is an effective theory for the high-gluon-density region of ultra-relativistic particles.

We introduce both theories and we discuss connections between them.

We present phenomenological results derived from these connections.
