The Large Hadron Collider (LHC) at CERN near Geneva is an accelerator designed to collide protons at a centre-of-mass energy of √s = 14 TeV. It is operational since November 2009 and has delivered collisions up to an energy of √s = 7 TeV in 2010. The LHCb ...
Superconducting magnets submitted to large heat loads, as the low-β quadrupoles for the LHC luminosity upgrade, need the development of new concepts of cable electrical insulation featuring a He-II porous wrapping scheme. This paper reports and discusses r ...
The next generation of superconducting magnets for the interaction regions of particle colliders, as well as for fast cycled accelerators, will be confronted with large heat loads. In order to improve the evacuation of heat from the Nb-Ti coil towards He-I ...
Proton and carbon ion beams present advantageous depth-dose distributions with respect to X-rays. Carbon ions allow a better control of "radioresistant" tumours due to their higher biological response. For deep-seated tumours prot ...
The process gamma gamma -> phi J/psi is measured using a data sample of 825 fb(-1) collected with the Belle detector. A narrow peak of 8:8(-3.2)(+4.2) events, with a significance of 3.2 standard deviations including systematic uncertainty, is observed. The ...
The muon and anti-muon neutrino energy spectrum is determined from 2000-2003 AMANDA telescope data using regularised unfolding. This is the first measurement of atmospheric neutrinos in the energy range 2-200 TeV. The result is compared to different atmosp ...
New polyimide cable insulation schemes improving the cooling of Nb-Ti superconducting coils were recently developed to face the severe heat loads at which the next generation of superconducting accelerator magnets will work. In order to qualify the new ins ...
CERN is presently designing a new chain of accelerators to replace the present Proton Synchrotron (PS) complex: a 160 MeV room-temperature H- linac (Linac4) to replace the present 50 MeV proton linac injector, a 3.5 GeV Superconducting Proton Linac (SPL) t ...
In one of its acceptation, the word quench is synonym of destruction. And this is even more consistent with reality in the case of the Large Hadron Collider dipole magnets, whose magnetic field and stored energy are unprecedented: the uncontrolled transiti ...
A systematic approach for a model independent description of phenomenology at the LHC is presented. The most general linear interaction of scalars and fermions with pairs of standard model fields is considered at the renormalizable level. Searches for the ...
