 Measurement of the inclusive cross-section for the production of jets in association with a $Z$ boson in proton-proton collisions at 8 TeV using the ATLAS detector The inclusive cross-section for jet production in association with a $Z$ boson decaying into an electron-positron pair is measured as a function of the transverse momentum and the absolute rapidity of jets using 19.9 fb$^{-1}$ of $\sqrt{s} = 8$ TeV proton-proton collision data collected with the ATLAS detector at the Large Hadron Collider.

 Cosmological scalar fields and Big-Bang nucleosynthesis / Arbey, A. ; Coupechoux, J.-F. Scalar fields are widely used in cosmology, in particular to emulate dark energy, for example in quintessence models, or to explain dark matter, in particular within the fuzzy dark matter model.
