- 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 ...

- More on Relation of Standard Model Flavor Hierarchies and Euclidean 3-Space Geometry
-
Normal 0 MicrosoftInternetExplorer4 The remarkable coincidence of the empirical Pythagorean equation for SM flavor hierarchy angles with the outer euclidean symmetry 3-space metric equation for constant vector direction angles is the data evidence of ...

- 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 ...

- An Easy Problem
-
Yesterday I chaired the selection committee to choose the student who will be hired in the AMVA4NewPhysics network by the Padova section of INFN, and during the interviews I asked all candidates a couple of "easy" physics questions, meant to test ...

- 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 ...
