37. TMD factorization: status and implications

Ignazio Scimemi (Universidad Complutense (ES))

19/11/2018, 14:00

4. TMDs and parton showers

Hannes Jung (Deutsches Elektronen-Synchrotron (DE))

19/11/2018, 14:35

I will discuss using TMDs obtained with the Parton Branching method to create Parton Showers which follow the TMDs. Exempels of applications using TMD parton showers will be shown.

21. Recent results on low x TMDs and their journey to large x

Martin Hentschinski (Universidad de las Americas, Puebla)

19/11/2018, 15:00

I will give an overview of recent results on low x TMDS and their systematic extension into the large x region.

39. Double parton distributions: evolution, initial conditions and transverse momentum dependence

Anna Stasto (Penn State)

19/11/2018, 15:50

In the first part of the talk I shall discuss the problem of initial conditions for the double parton distributions, and how to use the information about the momentum sum rule together with the initial conditions for the single parton distributions. In the second part of the talk I will address the transverse momentum dependence in the double parton distributions. The construction is based on...

6. Factorization of double Drell–Yan

Mr Riccardo Nagar (Deutsches Elektronen-Synchrotron DESY)

19/11/2018, 16:15

In a double Drell–Yan process two hard interactions take place instead of a single one, leading to a more complex momentum, spin, and color structure of the diagrams involved. Higher-precision predictions for the LHC and the prospect of future high-energy colliders motivate the efforts for a rigorous field-theoretical description of these kinds of processes, as well as for the broader class of...

33. Quark-Hadron duality in Deep Inelastic Scattering

Enrique Ruiz Arriola (Universidad de Granada)

19/11/2018, 16:40

High energy inclusive processes are naturally formulated in terms of partonic distributions, but in fact all exclusive processes correepond to resonances and completeness of states requires a non-trivial relation betwenn inclusive and exclusive measurements. We review how Quark-Hadron Duality (QHD) for (u,d) flavors at high energies and in the scaling regime suggests a radial and angular...

35. Small qT factorization and the soft function for top pair production at NNLO

Sebastian Sapeta (IFJ PAN)

19/11/2018, 17:05

The cross section for top quark pair production factorizes at small transverse momentum of the heavy quark pair, qT. One of the key ingredients that appears in the factorization formula is the soft function, which mediates soft gluon exchanges between particles. I shall present the complete result for the small-qT soft function at the next-to-next-to-leading order. This is the last missing...
