“…The search is optimized separately for the vector boson fusion and the gluon fusion production processes. No significant excess is observed above the background expectation, and upper limits are set on the Higgs boson production cross section. …”

“…Jets of particles in localized regions of phase space are produced from partonic hard-scatterings of quarks and gluons contained within protons and neutrons. In pp and d+Au collisions the produced jets fragment into many hadrons, which can then be reconstructed in the PHENIX detector. …”

“…Studied in details are also the collective phenomena arising due to the hydrodynamical stage of the system evolution from the initial hard scattered quarks and gluons to the hadronized particles. Recent ATLAS results on the total charged particle multiplicities and differential yields in pPb will be reviewed. …”

“…In addition, the measurement of production of vector bosons in association with heavy flavours allows to study c and b-quark parton distribution functions (PDFs) and gluon splitting effects. Also the corresponding measurements of $W+c$ and $Z+b(b)$ are reported and compared to predictions based on various PDFs in four and five-flavour schemes.…”

“…Then I will summarize recent progress in calculating these elements and their interplay at "NLO" -- "NLO" refers to an order $\sqrt{\alpha_s}$ correction to the plasma processes arising from the statistical fluctuations of soft gluons. These "NLO" calculations suggest a computational strategy where the influence of the Debye sector on the real time dynamics of the hard lightlike modes can be incorporated into a few medium coefficients (such as the drag coefficient and $\hat{q}$), which can be simulated with a Euclidean 3D dimensionally reduced theory. …”
