Superfluid helium cryogenics for the large hadron collider project at CERN

Excited Leptons at the CERN Large Hadron Collider

We analyze the potential of the CERN Large Hadron Collider (LHC) to search for excited spin-12 electrons and neutrinos. Assuming a SU(2)L⊗U(1)Y invariant model, we study in detail the single production of excited electrons and neutrinos and respective backgrounds through the reactions pp → e+e−V and e±νV with V = γ, W , or Z. We show that the LHC will be able to tighten considerably the direct ...

Tagging two-photon production at the CERN Large Hadron Collider

Tagging two-photon interactions offers a significant extension of the CERN LHC physics program. The effective luminosity of high-energy gg collisions reaches 1% of the proton-proton luminosity. The standard detector techniques used for measuring very forward proton scattering will allow a reliable separation of interesting two-photon interactions. Particularly exciting is the possibility of det...

The future of the Large Hadron Collider and CERN.

This paper presents the Large Hadron Collider (LHC) and its current scientific programme and outlines options for high-energy colliders at the energy frontier for the years to come. The immediate plans include the exploitation of the LHC at its design luminosity and energy, as well as upgrades to the LHC and its injectors. This may be followed by a linear electron-positron collider, based on th...

EUROPEAN ORGANIZATION FOR NUCLEAR RESEARCH European Laboratory for Particle Physics CRYOGENICS FOR THE LARGE HADRON COLLIDER

The Large Hadron Collider (LHC), a 26.7 km circumference superconducting accelerator equipped with high-field magnets operating in superfluid helium below 1.9 K, has now fully entered construction at CERN, the European Laboratory for Particle Physics. The heart of the LHC cryogenic system is the quasi-isothermal magnet cooling scheme, in which flowing two-phase saturated superfluid helium remov...
