Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
The Large Hadron Collider (LHC) has been producing pp collisions at 7 and 8 TeV since 2010 and promises a new era of discoveries in particle physics. One of its experiments, the Large Hadron Collider beauty (LHCb) experiment, was constructed to study CP vi ...
I will discuss several possible choices for the mass scale M of the Majorana leptons, complementing the Standard Model to describe neutrino masses and oscillations. Depending on M, they can or cannot accommodate eV neutrino anomalies, lead to baryogenesis, ...
Our knowledge of our universe is deeply related to our understanding of physics at the sub- atomic scale. Indeed, at its early stage, our universe was so hot and so dense that the only relevant interactions were those between fundamental particles. Therefo ...
The LHCb experiment at CERN has been designed to perform high precision measurements of B meson decays. In this thesis the LHCb magnetic field parameterization and the emulation of the LHCb Silicon Tracker noise reduction algorithms are discussed. Both stu ...
The possibility of improving the limit on the branching fraction of the lepton flavor violating decay tau (+/-) -> A mu(+/-)A mu(+/-)A mu(a") at LHCb is discussed. It is shown that a simple, cut-based analysis is sufficient to improve the upper limit on th ...
Granular, solid targets made of fluidized tungsten powder or static pebble bed of tungsten spheres, have been proposed and are being studied as an alternative configurations towards high-power (1MW of beam power) target systems, suitable for a future Super ...
In thermal equilibrium the ground state of the plasma of Standard Model particles is determined by temperature and exactly conserved combinations of baryon and lepton numbers. We show that at nonzero values of the global charges a translation invariant and ...
The lifetime of the tau lepton is measured using the process e(+) e(-) -> tau(+) tau(-), where both tau leptons decay to 3 pi nu(tau). The result for the mean lifetime, based on 711 fb(-1) of data collected with the Belle detector at the Upsilon(4S) resona ...
Using infinite projected entangled-pair states, exact diagonalization, and flavor-wave theory, we show that the SU(4) Heisenberg model undergoes a spontaneous dimerization on the square lattice, in contrast with its SU(2) and SU(3) counterparts, which deve ...
We explore the dark matter interpretation of the anomalies claimed by the DAMA and COGENT experiments, in conjunction with the various null direct-detection experiments. An independent analysis of the COGENT data is employed and several experimental and as ...
