Lay Summary (French)

Lead
Le grand collisionneur de protons (LHC) du laboratoire européen pour la physique des particules (CERN, Genève) a été construit pour explorer, au niveau le plus fondamental possible, les constituants élémentaires de la matière et leurs interactions. L'expérience LHCb porte un nom suggestif; en effet, son but principal est de tirer parti de l'énorme quantité de quark lourds appelés "b" produite au LHC dans les collisions entre protons de très haute énergie (correspondant à l'énergie acquise dans une différence de potentiel électrique de plusieurs fois mille milliards de volts). L'étude de certaines désintégrations rares des particules contenant un quark lourd permet de tester les prédictions du "Modèle Standard", la théorie minimale décrivant tous les processus connus en physique des particules élémentaires. Si l'expérience révélait que certaines prédictions sont incorrectes, alors elle révélerait du même coup l'existence de nouveaux phénomènes encore inconnus.
Lay summary
L'expérience LHCb a été construite par une collaboration internationale de plusieurs centaines de physiciens, y compris les membres du Laboratoire de Physique des Hautes Energies de l'EPFL qui ont pris des responsabilités importantes dans l'élaboration et la mise sur pied du projet dès son origine. Ils ont en particulier développé et construit une partie de l'appareillage de l'expérience, incluant des détecteurs à micro-pistes de silicium et l'électronique de lecture des signaux. LHCb a enregistré efficacement des données d'excellente qualité durant la première période d'exploitation du LHC, entre fin 2009 et début 2013, à la moitié de l'énergie nominale. L'analyse de cette énorme masse de données, à laquelle le groupe de l'EPFL prend une part active, a produit de nombreuses nouvelles observations et mesures, publiées dans plus de 300 articles scientifiques, mais n'a pas (encore) permis de trouver la faille du Modèle Standard. Des exemples d'analyses faites à l'EPFL sont l'étude de la violation de la symétrie entre matière et anti-matière dans la désintégration de particules contenant un quark lourd, ainsi que de la polarisation du photon émis dans la désintégration d'un quark "b" en un quark "s". L'expérience continue maintenant à tourner pendant la deuxième période d'exploitation du LHC (2015-2018) à une énergie presque doublée, ce qui permet d'augmenter la sensibilité statistique de l'expérience. En 2019, l'expérience sera mise à jour afin d'en décupler le potentiel. Pour ceci, le groupe de l'EPFL a développé de nouveaux "détecteurs à traces" en fibres scintillantes lues par des photo-détecteurs au silicium. La phase de développement se termine et laisse place dès 2016 à une phase de construction, avant l'installation au CERN prévue en 2019-2020. Ce subside permet de financer des doctorants et des postdocs pour exploiter l'expérience, construire les nouveaux éléments nécessaires à sa mise à jour, analyser les données et publier les résultats.

Lay Summary (English)

Lead
The Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN, Geneva) was built to explore, at the most fundamental possible level, the elementary consitutuents of matter and their interactions. The LHCb experiment has a suggestive name: indeed, its main goal is to exploit the huge number of heavy quarks called “b” produced at the LHC through the collisions between protons of very high energy (corresponding to the energy acquired in an electric potential difference of several thousands of billions of volts). The study of certain rare decays of the particles containing a heavy quark allows tests of predictions from the “Standard Model”, the minimal theory describing all known processes in elementary particle physics. If the experiment revealed that certain predictions are incorrect, it would then at the same time reveal the existence of new yet unknonwn phenomena.
Lay summary

The LHCb experiment was built by an international collaboration of several hundreds of physicists, including the members of EPFL’s High Energy Physics Laboratory who have taken important responsibilities for the design and realization of the project since its inception. They have in particular developed and built certain scientific equipment of the experiment, including silicon-strip detectors and electronics for the readout of the signals. LHCb has efficiently recorded data of excellent quality during the first period of LHC operation, between end 2009 and beginning 2013, at half of the nominal energy. The analysis of this huge dataset, to which the EPFL group is contributing actively, has resulted in a large number of new observations and measurements, published in more than 300 scientific articles, but has not (yet) unveiled any flaw of the Standard Model. Examples of analyses performed at EPFL are the study of the violation of the symmetry between matter and anti-matter in the decay of particles containing a heavy quark, as well as the investigation of the  polarisation of the photon emitted in the decay of a “b” quark into an “s” quark. The experiment now continues to run during the second LHC operation period (2015-2018) at almost doubled energy, which will increase the statistical sensitivity of the experiment. In 2019 the experiment will be upgraded in order to multiply its potential. Towards this goal the EPFL group has developed new tracking detectors made of scintillating fibres read out with silicon phot-multipliers. The R&D phase is reaching an end and the construction phase is starting in 2016, leading up to the installation at CERN foreseen in 2019-2020. This grant provides funding for PhD students and  postdocs to operate the experiment, analyse the data, publish the results, as well as build the new detector elements needed for the upgrade.

Abstract

The LHCb detector is designed for precise measurements of CP violation and rare B decays, exploiting the very large heavy quark production at CERN's Large Hadron Collider (LHC). The primary physics aims are to characterize in detail the flavour structure in the quark sector, and look for New Physics in the decay of charm and bottom hadrons.During the first LHC running period (November 2009 - February 2013), LHCb has efficiently recorded pp collisions at centre-of-mass energies up to 8 TeV, corresponding to a total integrated luminosity of 3 fb^-1. With these data the LHCb physics programme has been deployed, with over 300 physics papers published or submitted to peer-reviewed journals. Although much new territory has been explored, all results so far are consistent with the expectations of the Standard Model. After a two-year LHC shutdown, a new four-year run has started in 2015 at 13 TeV, during which the experiment is expected to collect 4 times more charm- and beauty-hadron decays than during the first run. In parallel the collaboration is preparing a major upgrade of the experiment to enable the collection of 5 fb^-1 per year (from 2021 onwards) with improved efficiency.Our particle physics group in Lausanne has played important roles in LHCb since the beginning of the project in 1995. Our detector construction and maintenance responsibilities cover the TELL1 common readout boards, the powering system and analogue transmission electronics for the silicon vertex detector VELO, and the downstream tracking stations (Inner Tracker) of the Silicon Tracker. In addition Switzerland has significantly invested in the upstream tracking stations (through University of Zurich) and in the online system, including the computer farm for the high-level trigger of the experiment. We are heavily involved in data analysis and in detector R&D in view of the upgrade of the downstream tracking stations, for which we have proposed a new technology based on scintillating fibres read out with silicon photomultipliers. We are starting the construction of these new tracking stations in 2016.Our objectives for the forthcoming three-year funding period 2016-2019 are the following:- Ensure appropriate maintenance of the detector systems under our responsibility so that they be fully functional throughout the 2015-2018 run, and participate in the data-taking operations;- Analyze actively the existing and forthcoming data with main emphasis on searches for New Physics effects, and disseminate the physics results in publications and conference presentations;- Build, test, and assemble components for the new scintillating-fibre tracker of the experiment.
