The CERN Large Hadron Collider (LHC) will store 2808 bunches per colliding beam, each bunch consisting of 1011 protons at an energy of 7 TeV. If there is a failure in an element of the accelerator, the resulting beam losses could cause damages not only to ...
I give a pedagogical introduction to the concepts and the tools that are necessary to study particle physics models in higher dimensions. I then give a more detailed presentation of warped compactifications and discuss their possible relevance to the hiera ...
The characteristics of synchrotron X-ray sources-quite different from those of conventional sources-are exploited by several new imaging techniques. These techniques expand the capabilities of conventional radiology and find interesting application in spec ...
Events from the e+e-→Zγ process with hard initial-state radiation collected with the L3 detector at centre-of-mass energies between 183 and 209 GeV are used to measure the mass of the Z boson. Decays of the Z boson into hadrons or muon pairs are considered ...
The e+e-→e+e-hadrons reaction, where one of the two electrons is detected in a low polar-angle calorimeter, is analysed in order to measure the hadronic photon structure function F2 γ. The full high-energy and high-luminosity data set, collected with the L ...
Six-dimensional orbifold models where the Higgs field is identified with some internal component of a gauge field are considered. We classify all possible T-2/Z(N) orbifold constructions based on a SU(3) electroweak gauge symmetry. Depending on the orbifol ...
The absolute muon flux between 20 and 3000 GeV is measured with the L3 magnetic muon spectrometer for zenith angles ranging from 0°to 58°. Due to the large exposure of about 150 m2sr d, and the excellent momentum resolution of the L3 muon chambers, a preci ...
Geant4 is a toolkit for simulating the passage of particles through matter. It includes a complete range of functionality including tracking, geometry, physics models and hits. The physics processes offered cover a comprehensive range, including electromag ...
Events stemming from the pair-production of Z bosons in e+e - collisions are studied using 217.4 pb-1 of data collected with the L3 detector at centre-of-mass energies from 200 GeV up to 209 GeV. The special case of events with b quarks is also investigate ...
The three different helicity states of W bosons produced in the reaction e+e- → W+W- → lvqq̄′ at LEP are studied using leptonic and hadronic W decays. Data at centre-of-mass energies √s = 183-209 GeV are used to measure the polarisation of W bosons, and it ...
