Presented here is a description of the PICO experiment, which has achieved one of the world’s best exclusions for the detection of Weakly-Interacting Massive Particles (WIMPs): the leading candidate for the Dark Matter particle. This podcast is a little longer … Continue reading →

Using an extra dimension in the analysis of neutrino events to have a close look at what’s happening. http://news.fnal.gov/2016/07/getting-feel-taste-neutrinos/, by David Coplowe, a physicist at Oxford University.

Do the photons between grazing lead nuclei collide? http://news.fnal.gov/2016/07/shining-light-lead-lhc/, by Bo Jayatilaka.

The first 13 TeV results from CMS at CERN firmly confirm the Standard Model. http://news.fnal.gov/2016/06/triumphant-standard-model/, by Don Lincoln.

CMS observes the creation of W boson from the collision of photos in the proton’s magnetic field. Audio note: this episode contains some mysterious drop-outs of audio frames. We are investigating the cause of this–it should be solved by the … Continue reading →

Many pro sports use advanced metrics that combine statistics to evaluate whether a player is a potential star or not. Similarly, physicists use combined variables to assess whether a given LHC collision event might have resulted from supersymmetry. Photo: John Martinez Pavliga

CMS scientists have defined a new set of variables, called “razor variables,” that are being used to search for dark matter in data recorded using the Large Hadron Collider.
