TL;DR

This paper demonstrates the feasibility of measuring energy flow from minijets in hadronic collisions at the LHC using forward and central detectors, incorporating advanced QCD calculations.

Contribution

It introduces a Monte Carlo framework that accounts for QCD logarithmic corrections in energy flow predictions for events with forward and central jets.

Findings

First calorimetric measurements of energy flow in large rapidity intervals.

Parton-shower calculations align with expected energy flow patterns.

Potential to analyze multiple parton collision effects.

Abstract

We observe that at the Large Hadron Collider, using forward + central detectors, it becomes possible for the first time to carry out calorimetric measurements of the transverse energy flow due to "minijets" accompanying production of two jets separated by a large rapidity interval. We present parton-shower calculations of energy flow observables in a high-energy factorized Monte Carlo framework, designed to take into account QCD logarithmic corrections both in the large rapidity interval and in the hard transverse momentum. Considering events with a forward and a central jet, we examine the energy flow in the interjet region and in the region away from the jets. We discuss the role of these observables to analyze multiple parton collision effects.
