Alineamiento Global del Detector AFP Utilizando Eventos Exclusivos de Dos Muones

Abstract

The ATLAS Forward Proton detector (AFP), is a set of detectors located next to the ATLAS detector, which has the purpose of measuring the position and fractional energy loss of protons produced at 13 TeV in diffractive processes. One of the important tasks to be performed when taking data with a detector is its calibration. In the case of AFP, the global alignment of fractional energy loss and position of the protons is performed in order to reduce the uncertainties associated with the measurements made at each of the stations. For the present work, data colleted by the ATLAS experiment during run 2 of the LHC (2017). The data are have been process according to high quality filters, generating lists called GRLs (Good Run List). The events of the GRL data are selected according to same criteria established for the process in question and used to perform the global alignment of the AFP detectors.
