The HERA challenges for LHC

TL;DR

This paper reviews HERA collider results on QCD dynamics, highlighting potential implications for LHC physics and the importance of understanding deviations from DGLAP evolution for future searches beyond the Standard Model.

Contribution

It emphasizes the significance of HERA's findings on QCD at high energy and discusses their potential impact on LHC physics and beyond Standard Model searches.

Findings

HERA provided extensive data on proton structure functions.

Some observations at HERA deviate from DGLAP predictions.

Deviations at HERA may influence LHC search strategies.

Abstract

Over the last two decades, the HERA collider has provided a large amount of new information about QCD dynamics at high energy. While the most appreciated are the measurements of the proton structure functions in a wide range of parton momentum x and virtuality Q^2, it is hard to believe that some of the observations at HERA which do not fit the simple picture of DGLAP dynamics would not get amplified at the LHC, possibly rendering certain approaches to searches beyond the Standard Model inadequate.
