The W Factor
Tommaso Dorigo has a wonderful post today on the W boson width, which is measured to be $2.032 \pm 0.071$ GeV. Since he could not post the picture showing the full collection of these results, I will post it here. 
Observe that the result agrees very well with 'Standard Model' predictions, based on nine simple decay channels of the W boson into pairs. Don't ask me about the LEP-2 error bars.

Thanks for posting the diagram, and thanks to Tommaso for many interesting posts. The Standard Model of particle physics has many supporting experiments.
There is a model of cosmology--calling it "LCDM" didn't catch on, neither did naming it "Concorde cosmology" for a plane that no longer flies. Recently they have tried to name it "standard cosmological model" in imitation of particle physics. Too confusing!
Thanks Louise. Regarding Gravity, I am pleased to see that you registered for GRG18. I look forward to meeting you at last.
