Sumario: | This report describes the technical design and outlines the expected performance of the CMS-TOTEM Precision Proton Spectrometer (CT-PPS). CT-PPS adds precision proton tracking and timing detectors in the very forward region on both sides of CMS at about 200m from the IP to study central exclusive production (CEP) in proton-proton collisions. CEP provides a unique method to access a variety of physics topics at high luminosity LHC, such as new physics via anomalous production of $W$ and $Z$ boson pairs, high-$p_T$ jet production, and possibly the production of new resonances. The CT-PPS detector consists of a silicon tracking system to measure the position and direction of the protons, and a set of timing counters to measure their arrival time with a precision of the order of 10 ps. This in turn allows the reconstruction of the mass and momentum as well as of the $z$ coordinate of the primary vertex of the centrally produced system. The framework for the development and exploitation of CT-PPS is defined in a Memorandum of Understanding signed by CERN as the host laboratory and the CMS and TOTEM Collaborations. The expected performance of CT-PPS is discussed, including detailed studies of exclusive WW and dijet production. The planning for the implementation of the new detectors is presented, including construction, testing, and installation. |
