The ATLAS experiment was designed to explore a broad variety of phenomena
that may arise in the high energies proton-proton collisions at the Large
Hadron Collider (LHC). It was optimized for the search for the Higgs Boson
in the largest possible mass range as well as for the search for heavy new
particles such as those expected in supersymmetric models. The detector has
been...

Over the last year the CMS experiment at the CERN Large Hadron Collider has been collecting data for an integrated luminosity exceeding 5 inverse femtobarn at 7 TeV center of mass energy. The detector has shown excellent performance, with very good data taking efficiency since the very beginning. The operational experience during 2011 data taking will be discussed, focusing on relevant...

In the coming years different phases of upgrades for the LHC complex are foreseen, which will allow to extend the physics potential of its experiments. Through two different phases (namely phase-1 and phase-2), the average luminosity will be increased by a factor 5-10 above the design luminosity. Consequently, the detectors and the infrastructure of the DAQ system of the experiments will need...

Various parts of the CMS Level-1 hardware trigger will be upgraded to cope with increasing luminosity, using more selective trigger conditions at Level-1 and improving the reliability of the system. Many trigger subsystems use FPGAs (Field Programmable Gate Arrays) and will benefit from developments in this technology, allowing much more logic into a single FPGA chip, thus reducing the number...

The ATLAS calorimeter is composed by detectors based on different
techniques to exploit the best performance while maintaining a
sufficient radiation resistance in each geometrical region. Radiation
resistant liquid argon (LAr) sampling calorimeters are used for all
electromagnetic sections, for the endcap (HEC) and forward (FCal)
hadronic sections. The most central hadronic section is...

Calorimetry, muon detection, vertexing, and tracking will play a central role in determining the physics reach for the High Luminosity (HL) Large Hadron Collider (LHC) Era demanding unprecedented options and R&D efforts necessary to upgrade the current LHC detectors and enabling discoveries. Several detector upgrades are foreseen for the Compact Muon Solenoid (CMS) detector currently...

The forward physics experiment TOTEM at LHC (Interaction Point 5) is dedicated to measure the total and elastic p-p cross-section and to study diffractive processes. The TOTEM detector system is composed of 2 telescopes (T1, T2), and the Roman Pots, installed symmetrically on both sides of the IP 5. To cover the pseudo rapidity range from 3.1 to 4.7, the T1 detector is integrated in the CMS...

The LHCb High Level Trigger (HLT) is implemented in a farm of parallel-processing CPUs, and serves to reduce the event rate from an input of 1 MHz to an output rate of around 2 kHz, with a processing time of around 20 ms per event. In order to maximize efficiencies and minimize biases, the trigger is designed around highly inclusive selection algorithms, culminating in a novel boosted decision...

The ALICE Experiment at the LHC is providing precision measurements on strongly interacting matter at unprecedented high-energy density by studying A-A, p-A and pp collisions. This will allow a detailed characterization of the properties of the Quark-Gluon Plasma in the first running period up to 2017. Further progress in understanding the dynamics of this condensed phase of QCD will need to...

The upgrade of the LHCb experiment, planned for 2018, will transform the entire readout to a triggerless system operating at 40 MHz.
All data reduction algorithms will be executed in a high level software farm, with access to all event information. This will enable the detector to run at luminosities of above $2\times10^{33} \mathrm{cm}^{-2}\mathrm{s}^{-1}$ and explore New Physics effects...

The long-term physics program of the ALICE experiment at the CERN LHC relies on a major upgrade of the central barrel detectors planned for the second long LHC shutdown (LS2) that as of today is scheduled for 2017/18. A key aspect of the global upgrade strategy is to develop the capability to collect Pb-Pb data at an interaction rate up to 50 kHz, with the least possible bias, and improved...

The upgrades for the ATLAS Pixel Detector will be staged in preparation for high luminosity LHC. The first upgrade for the Pixel Detector will be the construction of a new pixel layer which will be installed during the first shutdown of the LHC machine, foreseen in 2013-14. The new detector, called the Insertable B-layer (IBL), will be installed between the existing Pixel Detector and a new,...

LHC is expected to increase its luminosity above the original nominal value of $1\times10^{34}\,\mathrm{cm}^{−2}\mathrm{s}^{−1}$, eventually achieving an order of magnitude increase after major upgrades will be performed after 2020. This configuration of the machine is known as High Luminosity-LHC (HL-LHC). CMS plans two upgrades of the tracking system.
In the second half of this decade the...
