25. Twist-three quark TMDs from back-to-back dijet production in DIS

We consider dijet production in deep inelastic scattering (DIS) at small $x$, focusing on contributions involving the quark background field of the target. We first derive the quark-gluon and quark-antiquark dijet cross sections in general kinematics at next-to-eikonal (NEik) accuracy in the high-energy limit. We then perform the expansion in the back-to-back limit at leading and...

38. Factorization and virtuality evolution of jet functions in nuclear collisions

In this work we develop a new framework to include virtuality effects in jet quenching in heavy-ion collisions using standard perturbative techniques. Starting from a Glauber description of the colliding nuclei, we first derive a factorized expression for jet cross sections that involves the definition of jet functions in a QCD medium. Remarkably, the factorized jet cross section retains an...

48. Reassessing the Connection Between the Color Glass Condensate and TMD PDFs

Benjamin Guiot (Universidad Técnica Federico Santa María)

Paying particular attention to the different types of gluons, collinear, soft and glauber, we show that the CGC Wilson lines usually identified as part of the TMD PDF operator should instead be interpreted as the equivalent of a soft factor. We argue that, in its standard formulation, the CGC does not contain the collinear sector required for a meaningful comparison with TMD factorization. We...
