 Highly occupied gauge theories in 2+1 dimensions: self-similar attractor / Boguslavski, K. ; Kurkela, A. ; Lappi, T. ; Peuron, J. Motivated by the boost-invariant Glasma state in the initial stages in heavy-ion collisions, we perform classical-statistical simulations of SU(2) gauge theory in 2+1 dimensional space-time both with and without a scalar field in the adjoint representation.

 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.
