Towards precision determination of uPDFs
Magnus Hansson (Lund University), Hannes Jung (DESY)
TL;DR
This paper presents a method to determine the gluon unintegrated Parton Density Function (uPDF) from dijet production data at HERA, providing insights into the intrinsic transverse momentum distribution at small kt.
Contribution
It introduces a novel fit approach to extract the gluon uPDF from experimental data, including the first attempt to constrain the intrinsic transverse momentum distribution at small kt.
Findings
Reasonable agreement with HERA dijet data
First constraints on intrinsic transverse momentum at small kt
Improved understanding of gluon uPDFs
Abstract
The unintegrated Parton Density Function of the gluon is obtained from a fit to dijet production in DIS as measured at HERA. Reasonable descriptions of the measurements are obtained, and a first attempt to constrain the intrinsic transverse momentum distribution at small kt is presented
