Performance of the CDF Miniplug Calorimeters

Two Miniplug calorimeters, designed to measure the energy and lateral position of particles in the forward pseudorapidity region of 3.6<|\eta |<5.1, have been installed as part of the CDF upgraded detector for Run II at the Tevatron. Proton-antiproton beams are colliding at $\sqrt{s}$=1.96 TeV. One year after installation, Miniplug detector performance and first results are presented.Comment: 5 pages, 8 figures Proceedings 8th Topical Seminar on Innovative Particle and Radiation Detectors 21-24 October 2002 Siena, Ital

Jets at CDF

Recent jet results in $p\bar{p}$ collisions at $\sqrt{s}$=1.96 TeV from the CDF experiment at the Tevatron are presented. The jet inclusive cross section is compared to next-to-leading order QCD prediction in different rapidity regions. The $b$-jet inclusive cross section is measured exploiting the long lifetime and large mass of $B$-hadrons. Jet shapes, W+jets and W/Z+photon cross sections are also measured and compared to expectations from QCD production.Comment: 5 pages, 6 figures Presented at the workshop on Low-x Physics, Lisbon, Portugal, June 28-July 1, 200

Diffractive physics: from the Tevatron to the LHC

Measurements of soft and hard diffractive processes have been performed at the Tevatron p-pbar collider during the past decade. Diffractive events are studied by means of identification of one or more rapidity gaps and/or a leading antiproton. Here, results are discussed within the Tevatron data and compared to those obtained at the HERA ep collider. The traditional ``pomeron'' is described within the framework of QCD and the issues discussed include pomeron structure, diffractive cross section factorization, and universality of rapidity gap formation. Exclusive dijet and low-mass state production in double-pomeron exchange processes, including predictions for Higgs production at the LHC from dijet measurements at the Tevatron.Comment: 4 pages, 2 figures Pub.

Upgrades for the Precision Proton Spectrometer at the LHC: Precision Timing and Tracking Detectors

The CMS-TOTEM Precision Proton Spectrometer (CT-PPS) is an approved project to add tracking and timing information at approximately $\pm$210~m from the interaction point around the CMS detector. It is designed to operate at high luminosity with up to 50 interactions per 25~ns bunch crossing to perform measurements of e.g. the quartic gauge couplings and search for rare exclusive processes. During 2016, CT-PPS took data in normal high-luminosity proton-proton LHC collisions. In the coming years, high radiation doses and large multiple-vertex interactions will represent difficult challenges that resemble those of the high-luminosity LHC program. A coordinated effort of detector upgrades with the goal of reaching the physics goals while mitigating the degradation effects is under way. Upgrades to the tracking and timing detectors are discussed.Comment: 4 pages, 2 figures - Proceedings of Diffraction 2016, International Workshop on Diffraction in High-Energy Physics, Acireale (Italy), September 2-8, 201
