The DIMO6Fit Team has been the driving force behind two the observation of two important processes at the LHC with the ATLAS detector: The scattering of two same-sign W bosons as well as the production of two W bosons from the scattering of two photons. Whilst not entirely surprising - these processes are predicted in the SM - these observations were the result of years of hard work (and two pictures of candidate events are attached below). The team has been very involved with the data taking and has taken the lead in making sure, that the detector can detect electrons well, which are used in the measurements. But it's not enough to just hunt for the new - more precise measurements of tried and trusted can reveal on closer look something surprising. In line with this, the DIMO6Fit team studied closely the production of two opposite-sign W bosons in proton collisions, . Both has led to a better understanding of these two processes within the Standard Model framework. On top of that, we have started to used these measurements to looks for signs of small, additional interactions not described by the SM. Combined with new predictions and innovative ways to determine backgrounds, the most precise measurements of WW production up to date have been carried - with results in the pipeline that remove any restrictions on the number of additional quarks or gluons production in the event. Together with other results, these measurements were taken by the DIMO6Fit team and turned into a stringent test of how well the Standard Model work. In a combination with other final states, small deviations would be amplified in noticeable signals. These fits were the first of their sort that looked simultaneously at results of diboson production, Higgs and top quark production. So far – with no result. But this is interesting and important in itself: The SM is still the best theory we have. Despite this, there are facts that it cannot explain, Dark Matter, Antimatter-Asymmetry and the large mass differences between otherwise very similar elementary particles. We will continue to look for cracks in the SM to see where we can start to look beyond it.
