17. Parton distributions for precision LHC phenomenology

Juan Rojo

2/2/11 16:30

The precision determination of parton distributions is an essential ingredient for LHC phenomenology. In this talk we review recent progress in the NNPDF determnation of parton distributions. We estimate theoretical uncertainties in LHC observables arising from heavy quark mass effects. We show how to use Bayesian inference to determine the impact of new data into PDFs without the need of...

19. A comparative study of small x Monte Carlos with and without QCD coherence effects

Michal Deak

2/2/11 17:30

We compare two Monte Carlo implementations of resummation schemes for the description of parton evolution at small values of Bjorken x. One of them if based on the BFKL evolution equation and generates fully differential parton distributions in momentum space making use of reggeized gluons. The other one is based on the CCFM partonic kernel where QCD coherence effects are introduced. It has...

20. Transverse-momentum resummation in Drell-Yan process at NNLL accuracy.

Giancarlo Ferrera

2/2/11 18:00

We consider the transverse-momentum (q_T) distribution of Drell--Yan lepton pairs produced in hadron collisions. At small values of q_T, we resum the logarithmically-enhanced perturbative QCD contributions up to next-to-next-to-leading logarithmic accuracy. At intermediate and large values of q_T, we consistently combine resummation with the known next-to-leading order perturbative result. All...
