In this paper, we present a review of forward physics measurements performed with LHC Runs 1 and 2 data. In particular, measurements based on proton–proton collisions with different center-of-mass energies (0.9–13 TeV) are reviewed. We focus on measurements exploring the forward phase space using the available instrumentation at the different LHC experiments, and report on forward jet and forward energy flow measurements.

We simulate proton–proton collisions to calculate the energy flow with four different classes of events: hard scattering, diffractive and non-diffractive enriched interactions and inclusive minimum bias. We use cosmic ray Monte Carlo event generator to determine the energy flow for the above-mentioned classes in pseudorapidity range 1.9[Formula: see text] 4.9 at [Formula: see text] = 7 TeV in pp collisions. A comparison of model predictions to the LHCb data, obtained with the same pseudorapidity and center-of-mass energy, is presented and discussed. While predictions of the models are compatible with the experimental measurements, none of them is able to completely reproduce all the results.

The success of the theory of Quantum Chromodynamics (QCD) in describing processes controlled by the strong interaction is generally seen as a triumph of modern particle physics. This paper reviews recent QCD measurements using hadronic jet final states from the Fermilab Tevatron, DESY's HERA, and CERN's LEP colliders. Recent advancements in the measurements of jet production cross sections, events shapes, and energy flow, along with improved theoretical calculations, allow for new levels of precision in the study of the physics of strong interactions and point to areas in need of further refinement.

Among most recent LHCb measurements relevant in the context of low-x physics include forward energy flow, Z and W cross-section measurements. The energy flow measurements map the forward LHCb acceptance for four classes of events, namely inclusive minimum bias, non-diffractive, diffractive and hard- pT collisions. Estimates from highenergy collision generators - i.e. various PYTHIA tunes and cosmic-ray generators - were compared to the measurement values. Z→ µ+µ+ and W± → µ+µ+ ν (v-) production is measured based on data collected at 7 TeV, results are shown differentially and compared to theoretical pQCD predictions.
