Centauros and CDF’s multi muon / lepton jets

An unexpected bump has the particle physics world busy tonight; (we’re too sedate to be “aflame”). The bump was discovered at Fermilab by the CDF collaboration: Study of multi-muon events produced in p-pbar collisions at sqrt(s)=1.96 TeV”, hep-ex/0810.5357. In short, they’ve discovered a particle that seems to produce jets of leptons.
CDF found that they have [...]

Help Save Bou’s Brain!

Things are flying in the physics world and there’s amazing things going on economically. And I owe some posts on these subjects.
But right now, more important for the brotherhood of blogs, is one of our own; Boudicca needs us. Her brain is at stake. a natural math talent could go to mush. We need to [...]

A New Parameterization for 3×3 Unitary Matrices

Given my final success in writing the CKM matrix as the sum of a real 1-circulant matrix and an imaginary 2-circulant matrix, the next step is to write down the parameterization that allows any 3×3 unitary matrix to be written in this elegant and natural form. Following the method used earlier to parameterize unitary 3×3 [...]

CKM in MNS form! Victory!

The MNS matrix (in tribimaximal form, which is compatible with all experimental measurements) can be written in elegant form as a unitary matrix which is the sum of a real 1-circulant matrix and an imaginary 2-circulant matrix. See Doubly Magic Matrices and the MNS. Now I’ve got the CKM matrix in the same form. And [...]

CKM as a magic unitary matrix II

It seems much longer but it was only two months ago that I wrote a post giving the CKM matrix in magic unitary form. With half the Nobel prize in physics going to Kobayashi and Maskawa, the K and M of the CKM matrix, I should include a quick update.
The CKM matrix is usually written [...]

The X(3872) Files: Scanning for new mesons

New mesons! Let’s begin with a picture (from encarta) showing how new particles (states) were discovered back in the good old days:

Work on the big meson paper is continuing. I’m almost done with the isoscalar mesons. So in addition to describing just what these things are, I’m including a few lines on the new J/psi [...]

The Barbarous Relic Rises Again

There’s gold in them thar’ shops: the rush is on
Tucked away beside the ornate entrance of the Savoy hotel in London are the discreet premises of ATS Bullion. Over the last few days staff there have witnessed an unprecedented phenomenon: queues.

The US Mint, responsible for ensuring an adequate supply of American coinage since 1792, has [...]
