Un-integrated PDFs in CCFM
Hannes Jung (DESY, Hamburg)
TL;DR
This paper investigates the properties of un-integrated parton distribution functions derived from CCFM evolution, focusing on their intrinsic transverse momentum distribution at low scales and the effects of scale variations.
Contribution
It provides a detailed analysis of uPDFs from CCFM, highlighting their behavior at low scales and under different scale choices, which was not thoroughly explored before.
Findings
uPDFs exhibit specific intrinsic transverse momentum distributions at low scales
Scale variations significantly affect the shape of uPDFs
Insights into the stability of uPDFs under different renormalization and factorization scales
Abstract
The un-integrated parton distribution functions (uPDFs) obtained from a CCFM evolution are studied in terms of the intrinsic transverse momentum distribution at low scales. The uPDFs are studied for variations of the renormalization and factorization scales.
