Chattez avec Graph Search
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 data sample recorded with the Belle detector at the Gamma (5S) energy provides a unique opportunity to study the poorly-known B-s(0) meson. Several analyses, made with a data sample representing an integrated luminosity of 23.6 fb(-1), are presen ...
LHCb is one of the four main experiments hosted at the Large Hadron Collider (LHC) at CERN. The LHC first started in September 2008 and, after a one-year hiccough, restarted in November 2009. In the course of three weeks, the HEP community witnessed the fi ...
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 ...
I consider the two-body decay of a particle at a hadron collider into a visible and an invisible particle, generalizing W -> ev, where the masses of the decaying particle and the invisible decay particle are, a priori, unknown. I prove that the transverse ...
We present a search for lepton-flavor-violating τ decays into three leptons (electrons or muons) using 782 fb-1 of data collected with the Belle detector at the KEKB asymmetric-energy e+ e- collider. No evidence for these decays is observed and we set 90% ...
The HiRadMat (High-Radiation to Materials) facility will allow testing of accelerator components, in particular those of the Large Hadron Collider (LHC) at CERN, under the impact of high-intensity pulsed beams. To reach this intensity range, the beam will ...
ISOLDE, the CERN Isotope Separator On-line DEvice is a unique source of low energy beams of radioactive isotopes - atomic nuclei that have too many or too few neutrons to be stable. The facility is like a small 'chemical factory', giving the possibility of ...
We present a study of atom-wall interactions in non-relativistic quantum electrodynamics by functional integral methods. The Feynman-Kac path integral representation is generalized when the particle interacts with a radiation field, providing an additional ...
Refined analysis, based on use of the Monte Carlo code MCNPX-2.4.0, is presented for the "H.B. Robinson-2 pressure vessel dosimetry benchmark", which is a part of the Radiation Shielding and Dosimetry Experiments Database (SINBAD). First, the performance o ...
The NA62 GigaTracker is a low mass time tagging hybrid pixel detector operating in a beam with a particle rate of 750 MHz. It consists of three stations with a sensor size of 60 x 27mm(2) containing 18000 pixels, each 300 x 300 mu m(2). The active area is ...
