mu = -geS/2m

for the magnetic moment. The straight forwards calcuation gives g = 2. It requires QED to get g – 2, where physics related to the Lamb shift give the departure. There are expected departures for the muon g factor, where there can be a virtual transition to the neutralino state.

]]>According to this, there is a possible experiment to verify if the g-factor has the same value between protons and antiprotons.

In this story, if the fields of either are of different strengths, then it would pose an additional problem for astrophysical phenomena and even nucleosynthesis / stellar evolution. (This linked article has the arXiv paper attached with it.) Again, this is a possible broken symmetry. ]]>

The Dirac equation is the spinorial form of the square root of the Klein-Gordon equation. The KG equation is a quantized form of the special relativistic momentum interval

(mc^2)^2 = E^2 – (pc)^2.

Going into the spinor mathematics of the Dirac equation is a bit beyond the scope of UT, and further requires some graphic math-tools not available here. So looking this up, even on wikipedia, is advised. However, the square root of an equation has two roots, and just as y = x^2 has positive and negative x’s (and recall the binomial equation) the same happens with the Dirac equation.

The physics of CP violations is a big issue, and Fermilab has been looking hard at CP violations with the T-quark, which follows the Desy results on the B-quark factory results. The T and B quarks are in the highest mass doublet of QCD.

]]>I think that a lot of conspiracy theorists think that gravity is a surface effect only. For example the moon pulls up the surface and thus cause tension inside the interior.

Reality is that gravity acts on every atom and in the complete Earth pulling all in the same direction. This includes the back side, the inner side, the left and right side and the front side. The resulting vectors is basically near zero in gravitational difference between the backside and the front-side. Earth does not get stretched like a big balloon but moves in the orbit as one whole thing.

]]>Why quote the chapter then? The suggestion that the positron (for example) would have negative active gravitational mass is the topic being discussed. You wouldn’t be trying to publicise your book, would you?
