The DPhP Atlas and CMS groups actively contributed to the first accurate measurements of the Higgs boson properties in the decay channel in two Z bosons, for the Atlas group, and two photons for the CMS group.
The most intriguing development in modern cosmology is to realise that the better part of the Universe is essentially of unknown nature. This conclusion relies on two types of observations.
Powerful fundamental interaction tests can be performed in the low energy domain, usually in the form of high precision measurements.
The physics of neutrinos is studied using different sources such as reactors, accelerators and radioactive sources.
