Discovery Potential

We study the Large Hadron Collider (LHC) discovery potential for Z' models with continuously distributed mass for [Formula: see text], 10 and 14 TeV center-of-mass energies. One of the possible LHC signatures for such models is the existence of broad resonance structure in Drell–Yan reaction pp →Z' + ⋯→l+l- + ⋯.

Discovery Potential

One of the main goals of the Large Hadron Collider is to find signatures of physics Beyond the Standard Model of particle physics. One way to do this is by studying with high precision the interactions of the Standard Model. In this talk, we address the discovery potential of New Physics in the exclusive channel pp → p X p which relies on the general purpose detectors at the Large Hadron Collider and their respective forward proton detector stations, located at about ~ 210 m w.r.t. the interaction point. These reactions are highly sensitive to quartic electroweak gauge interactions. As a proof of concept, we discuss the exclusive diphoton production at high diphoton invariant mass. We quote sensitivities on the anomalous γγγγ coupling for an integrated luminosity of 300 fb1 at the center-of-mass energy of 14 TeV.We also discuss the discovery potential of 3γZ anomalous quartic gauge coupling by measuring the pp → p(γγ → Zγ)p reaction.

The possibility of producing nonperturbative low-scale gravity states in collider experiments was first discussed in about 1998. The ATLAS and CMS experiments have searched for nonperturbative low-scale gravity states using the Large Hadron Collider with a proton–proton center-of-mass energy of 8 TeV. These experiments have now seriously confronted the possibility of producing nonperturbative low-scale gravity states which were proposed over 17 years ago. I will summarize the results of the searches, give a personal view of what they mean, and make some predictions for 13 TeV center-of-mass energy. I will also discuss early ATLAS 13 TeV center-of-mass energy results.

LUCID (LUminosity Cerenkov Integrating Detector) is the main luminosity monitor of the ATLAS (A Toroidal LHC Apparatus) experiment at the Large Hadron Collider (LHC) and in particular is the only one capable of providing bunch-by-bunch luminosity information, both online and offline, for all beam conditions and luminosity ranges. LUCID-2 refers to the detector upgrade designed to cope with the running conditions to be met in Run-2 (2015–2018): a center of mass energy of 13 TeV, with 50 pp interactions per bunch-crossing on average and a 25 ns bunch-spacing. This report summarizes all changes with respect to the detector deployed in Run-1 (2010–2012), including smaller sensors for higher granularity, new readout electronics for early signal digitization, and a completely new calibration concept guaranteeing long-term stability of the detector response. In addition, the overall detector performance in Run-2 and preliminary results on luminosity measurements are presented.

Higgs Search

The Large Hadron Collider(LHC) is a proton proton collider being built at CERN, Geneva which will collide two 7 TeV proton beams giving a center of mass energy of 14 TeV. The Compact Muon Solenoid (CMS) is a multi-purpose detector at the LHC which is designed to discover the Higgs boson over the mass range of 90 to 1000 GeV. Since LEP searches have put a 95% C.L. lower bound on (standard model) Higgs mass of 114.4 GeV and theory excludes mass above about 1 TeV, CMS should discover the Higgs if it exists. In this paper, we will review CMS's Higgs-discovery potential both in the Standard Model and the Minimal Supersymmetric Standard Model for Higgs bosons produced in gluon-gluon fusion and in vector boson fusion mechanisms. Particular emphasis will be placed on discovery in the early years of running with luminosity of about 2 × 1033cm-2/s.

Experiments will soon start taking data at CERN's Large Hadron Collider (LHC) with high expectations for discovery of new physics phenomena. Indeed, the LHC's unprecedented center-of-mass energy will allow the experiments to probe an energy regime where the standard model is known to break down. Here, the experiments' capability to observe new resonances in various channels is reviewed.

We report on studies of the sensitivity to extra gauge bosons of the reactions [Formula: see text] and eγ→νq+X to extract discovery limits for W′'s. The discovery potential for a W′ is, for some models, comparable to that of the LHC. These processes may be also useful for determining W′ and Z′ couplings to fermions which would complement measurements made at the Large Hadron Collider.

This is a review of searches for supersymmetry (SUSY) with the ATLAS detector in proton–proton collisions at a center-of-mass energy of 7 TeV at the Large Hadron Collider (LHC) at CERN. The review covers results that have been published, or submitted for publication, up to September 2012, many of which cover the full 7 TeV data-taking period. No evidence for SUSY has been seen; some possibilities for future directions are discussed.

A lepton collider capable of generating a luminosity of 5×1033 to 1×1034 at center-of-mass energies from 0.5 to 1.5 TeV would permit studies of fundamental interactions complementary to those planned at the Large Hadron Collider. Such energies would be more easily achieved for electrons at a linear collider than a conventional storage ring. We describe the Next Linear Collider (NLC), a proposed linear collider which utilizes room-temperature RF systems operating at 11.4 GHz to achieve the desired energies and room-temperature electromagnets and permanent magnets to achieve the extremely small beam sizes required to meet the specified luminosity goal. The NLC design has been optimized to permit electron–electron collisions as well as electron–positron collisions. We discuss a few of the detailed technical challenges which are posed by electron–electron collisions in the NLC parameter regime.

Abstract The Compact Muon Solenoid CMS is one of the major detectors of the LHC Large Hadron Collider accelerator. The second, a competitive brother, is Atlas. The accelerator complex in CERN was shut down for two years, after two years of exploitation, and will resume its work in 2015. During this break, called long shutdown LS1 a number of complex components, including electronics and photonics, will be intensely refurbished. Not only the LHC itself but also the booster components and detectors. In particular, the beam luminosity will be doubled, as well as the colliding beam energy. This means tenfold increase in the integrated luminosity over a year to 250fb−1/y. Discovery potential will be increased. This potential will be used for subsequent two years, with essentially no breaks, till the LS2 in 2017. The paper presents an introduction to the research area of the LHC and chosen aspects of the CMS detector modernization. The Warsaw CMS Group is involved in CMS construction, commissioning, maintenance and refurbishment, in particular for algorithms and hardware of the muon trigger. The Group consists of members form the following local research institutions, academic and governmental: IFD-UW, NCBJ-´Swierk and ISEWEiTI- PW.
