Still no Dark Matter in the latest analysis of LHC data…

Last night the ATLAS Collaboration released its latest search for dark matter and other beyond the standard model theories [1] based on the full dataset from the LHC Run I (2010-2012). By looking for proton-proton collisions where jets of hadronic particles are produced only in one direction (Figure 1), violating conservation of momentum only in appearance, we use ATLAS to search for  weakly interacting massive particles (WIMPs), such as dark matter particles. Because they are weakly interacting, the WIMPs escape ATLAS undetected and lead to what looks like missing momentum. Continue Reading ››

An ATLAS art installation at AlbaNova

Since early Autumn the ATLAS Art Installation is on the first floor of Stockholm House of Science at AlbaNova.
“In ATLAS we have made rather artistic animations of particle physics. In addition an artist has made the mural painting at CERN on one of the ATLAS buildings. The ATLAS events have also been rather artistic and made it to the many magazines and newspapers. I think that is why the installation is called the ATLAS Art Installation. I prefer to call it the People of ATLAS, as it is very much about the ATLAS people.” says Erik Johansson, professor at the Oskar Klein Centre.

What is the perfect size for a research group?

If you are thinking about your research group and are wondering on whether to include more people you better read this.

Ralph Kenna from the University of Coventry and Bertrand Berche from the University of Nancy (France) have analyzed the correlation between quality and research group size for different areas, based on data collected for the UK’s 2008 Research Assessment Exercise (RAE). Their findings are very interesting. While one could think that more people would get better results together, it seems that this is not true indefinitely.

Brainstorming

Brainstorming is one of the most known and diffused creativity boosting techniques used for getting fresh ideas. While brainstorming can also be done by individuals, it is most effective when done in a group of 10-12 people.
The technique is in principle very simple. A topic of discussion should be clarified and well defined at the beginning of a brainstorming session, possibly in terms of a question to answer. The definition of the task is important and one of the key of a successful brainstorming session.
