CERN is holding a scientific seminar at 9 am CEST on 4 July to deliver the latest update in the search for the Higgs boson.

The ATLAS and CMS experiments will deliver the preliminary results of their 2012 data analysis. The seminar comes on the eve of this year’s major particle physics conference, ICHEP, in Melbourne.

The 2012 LHC run schedule was designed to deliver the maximum possible quantity of data to the experiments before the ICHEP conference, and with more data delivered between April and June 2012 than in the whole 2011 run, the strategy has been a success. Furthermore, the experiments have been refining their analysis techniques to improve their efficiency in picking out Higgs-like events from the millions of collisions occurring every second. This means that their sensitivity to new phenomena has significantly increased for both years’ data sets. The crunching of all this data has been done by the Worldwide LHC Computing Grid, which has exceeded its design specifications to handle the unprecedented volume of data and computing.

If and when a new particle is discovered, ATLAS and CMS will need time to ascertain whether it is the long sought Higgs boson, the last missing ingredient of the Standard Model of particle physics, or whether it is a more exotic form of the boson that could open the door to new physics.

The Standard Model gives an extraordinarily precise picture of the matter that makes up all the visible Universe, and the forces that govern its behaviour, but there are good reasons to believe that this is not the end of the story. For example, we know from observation that the visible Universe is just four per cent of what seems to be out there.

The seminar will be webcast, from 8:55 am CEST. Tune in for the latest on the search for the Higgs at
