Abstract
Recent forward physics measurements performed with the CMS detector at the LHC are reviewed. The measurements of the pseudorapidity dependence of the energy and transverse energy density, inclusive energy spectrum in the very forward direction, and the very forward inclusive jet cross sections are presented. The results are also compared to the predictions of various models used to describe high energy hadronic interactions.
Highlights
Measurements in the forward region are essential for a better understanding of the complete final states at the LHC [1]
The CMS detector with its forward calorimeters as well as the beam line instruments allows to study a broad range of forward physics processes
The CMS Hadron Forward (HF) calorimeters are located on both sides of the interaction point and cover the pseudorapidity range 3.0 < |η| < 5.2
Summary
Measurements in the forward region are essential for a better understanding of the complete final states at the LHC [1]. In forward type of events, the particles are usually produced at small polar angles, θ, with respect to beam rapidity and the final states can contain large rapidity gaps devoid of hadronic activity. The CMS detector with its forward calorimeters as well as the beam line instruments allows to study a broad range of forward physics processes. The CMS Hadron Forward (HF) calorimeters are located on both sides of the interaction point and cover the pseudorapidity range 3.0 < |η| < 5.2. The very forward calorimeter, CASTOR, is located only at one side of the CMS detector and covers the range −6.6 < η < −5.2 [3]. Recent measurements performed with the HF and CASTOR calorimeters are presented
