One Dollar On 5.3 TeV

This is just a short post to mention one thing I recently learned from a colleague- the ATLAS experiment also seems to have collected a 5.3 TeV dijet event, as CMS recently did (the way the communication took place indicates that this is a public informati ...

Thank You Guido

It is with great sadness that I heard (reading it here first) about the passing away of Guido Altarelli, a very distinguished Italian theoretical physicist. Altarelli is best known for the formulas that bear his name, the Altarelli-Parisi equations (also k ...

In Plain English: Why Neutrino Mass and Oscillation Won A Nobel Prize.

H ow does knowing that neutrinos have mass, and change from one kind of particle to the other kind benefit all mankind?  Why should Takaaki Kajita and Arthur B. McDonald get a Nobel Prize for finding this?  What the heck is a neutrino anyway?  How does th ...

The Plot Of The Week: Light New Bosons Below The J/Psi

The graph below, I hope you'll agree, is significantly cooler and better-looking than the typical data display plots you get from high-energy physics analyses. Colours are bright, graphical symbols are clean, and one grasps the essence of the informat ...

Beta Decay For Teenagers

Yesterday my 16 year old son surprised me by explaining that he had been taught at school what alpha, beta, and gamma decays are. He had learned a lot, but I was able to add a little more background information to the picture as he asked me what was the ne ...

Another Higgs At 145 GeV?

A longtime follower of this blog, Tony Smith, pointed out to me today this arxiv paper published three days ago. In it, CMS data from Run 1 of the LHC are used to speculate that there might be a second Higgs boson hiding in the data at a mass of about 145 ...
