There are still some open question concerning the formation of our Universe.
Overview
Most of our current knowledge of the Universe comes from the observation of photons.
Photons have many advantages as cosmic information carriers: they are copiously produced, they are stable and electrically neutral, they are easy to detect over a wide energy range, and their spectrum carries detailed information about the chemical and physical properties of the source.

Goals:
Unifying the elementary constituants of matter and their interactions.
Atlas is one of the two general purpose detectors installed at the LHC which started operation in 2008. Atlas brings experimental physics into new territory. Discovering new processes and particles that change our understanding of energy and matter would be most exciting.
Goal
The main goal of the experiment was to perform a complete study of CP violation (CP is the symmetry linking particules and antiparticules) in the system of B mesons.
More generally the experiment studied the physics of heavy flavors: mesons and baryons with a b or a c quark and tau leptons.
Most of the content of the Universe, about 70%, is dominated by an energetic component that is neither matter nor radiation: dark energy. This mysterious component, first observed in 1998 with supernovae, revolutionized our vision of the evolution of the Universe and is one of the major discoveries of the end of the 20th century.
A characteristic scale of about 500 million light-years, acting as a "standard meter", is present in the distribution of matter on a cosmic scale.
Project context
The BTD project was developed in the framework of experiments aiming at the spectroscopy studies of radioactive nuclei using gamma-radiation and light particles in GANIL, mainly with SPIRAL and then SPIRAL2 beams. The purpose of these experiments is to study the structure of exotic nuclei in order to better understand the interactions that bind protons and neutrons and their reactions to different excitation modes (temperature, spin...).
Positron emission tomography (PET) is a powerful nuclear imaging technique used widely nowadays in oncology, cardiology and neuropsychiatry.
The PET technology consists in injecting the patient with a radioactive tracer, of interest to probe a biochemical process. The decay of the tracer emits a positron which annihilate with an electron. As a result of the annihilation, two photons with energy 511 keV are emitted back-to-back and registered by the dedicated detectors.

Oscillations between these neutrinos has been observed in many experiments and are already a compelling evidence of new physics beyond the Standard Model.

Une nouvelle génération d'observatoire pour explorer l'Univers à haute énergie.
Presentation
The D0 experiment was located at the proton-antiproton Tevatron collider at the Fermilab laboratory (Chicago, USA). There was two data taking periods: Run I from 1992 to 1996 with a center of mass energy of 1.8 TeV, and Run II from 2001 to 2011 with a center of mass energy of 1.96 TeV. Before the advent of the LHC, the Tevatron was the most energetic collider in the world and the only collider where the top quark as well as possibly a Higgs boson could be produced.
FELICE (acronym for "Future Electron LInear Collider Experiment") is a group of physicists and engineers working for the physics and detectors at the ILC (International Linear Collider). An electron-positron linear collider, with a centre-of-mass energy up to 1 TeV, has been chosen by a majority of physicists worldwide as the big project in High Energy Physics, after the commissioning of the LHC at CERN.

Résoudre la formation des galaxies : de la physique à petite échelle dans le contexte cosmologique

Aims:
One of the fundamental questions of today’s physics concerns the action of gravity upon antimatter.

The primary aim of this experiment is to determine how antimatter reacts to gravity.
