Unintegrated parton distributions and inclusive jet production at HERA
نویسندگان
چکیده
We describe how unintegrated parton distributions can be calculated from conventional integrated distributions. We extend and improve the ‘last-step’ evolution approach, and explain why doubly-unintegrated parton distributions are necessary. We generalise ktfactorisation to (z, kt)-factorisation. We apply the formalism to inclusive jet production in deep-inelastic scattering, mainly at leading order, but we also study the extension to next-to-leading order. We compare the predictions with recent HERA data.

Multi-jet production and transverse momentum dependent parton distributions
We study the impact of transverse-momentum dependent parton distributions on detailed features of multi-jet final states, focusing on angular jet correlations in DIS data. Monte-Carlo simulations of events containing multiple jets are central to a number of processes of interest at LHC energies, see e.g. [1], and further references in [2]. These complex events, characterized by multiple hard sc...
متن کاملUnintegrated parton distributions and pion production in pp collisions at SPS and RHIC energies
Inclusive cross sections for pion production in pp collisions are calculated for the first time fully based on unintegrated gluon, quark and antiquark distributions (uPDF). We use recently developed Kwieciński uPDF’s and different phenomenological fragmentation functions (FF) from the literature. In addition to the gg → g diagram we include also gq → q and qg → q diagrams for inclusive parton p...

In this talk, I present the brand new results from the H1 and ZEUS Collaborations on the combination of all previously published inclusive deep inelastic cross sections at HERA for neutral and charged current e±p scattering for zero beam polarisation and the corresponding parton distributions functions, HERAPDF 2.0, at up to next-to-next-to-leading order (NNLO). The results also include a new p...

متن کاملHard Photoproduction at HERA
In view of possible photoproduction studies in ultraperipheral heavy-ion collisions at the LHC, we briefly review the present theoretical understanding of photons and hard photoproduction processes at HERA, discussing the production of jets, light and heavy hadrons, quarkonia, and prompt photons. We address in particular the extraction of the strong coupling constant from photon structure funct...
