  38. The first report on “scaling” was presented by J. I. Friedman at the 14th International Conference on High Energy Physics in Vienna, 28 August-5 September 1968. The report was presented as paper no. 563 but not published in the Conference Proceedings. It was published as a SLAC preprint. The SLAC data on scaling were included in the Panofsky general report to the Conference where he says “... the apparent success of the parametrization of the cross-sections in the variable v/q2 in addition to the large cross-section itself is at least indicative that point-like interactions are becoming involved”.

  47. Zichichi A., New Developments in Elementary Particle Physics, Riv. Nuovo Cimento, 2, n. 14 (1979). The statement on page 2 of this paper, “ Unification of all forces needs first a Super symmetry. This can be broken later, thus generating the sequence of the various forces of nature as we observe them”, was based on a work by A. Petermann and A. Zichichi, in which the renormalization group running of the couplings using supersymmetry was studied with the result that the convergence of the three couplings improved. This work was not published, but perhaps known to a few. The statement quoted is the first instance in which it was pointed out that supersymmetry might play an important role in the convergence of the gauge couplings. In fact, the convergence of three straight lines (α-11 α-12 α-13 ) with a change in slope is guaranteed by the Euclidean geometry, as long as the point where the slope changes is tuned appropriately. What is incorrect about the convergence of the couplings is that, with the initial conditions given by the LEP results, the change in slope needs to be at MSusy ~ 1 TeV as claimed by some authors not aware in 1991 of what was known in 1979 to A. Petermann and A. Zichichi.

  53. No matter what the physics processes are, if their mathematical formulation can be expressed in terms of a relativistic, local, quantized, field theory (RQFT), these processes have to obey CPT invariance. Thus to violate this fundamental invariance of nature corresponds to break the basic conceptual structure of a RQFT. It took many decades to discover CPT invariance, as discussed in ref. [9]. And many other decades were needed to discover the convergence of the gauge forces at the Planck scale.

  57. As discussed in sect. 3, the nuclear forces mimic the existence of nuclear charges. If despite the non-existence of “nuclear charges”, CPT invariance holds, the mass associated with the opposite nuclear charges is the same as the one associated with the original nuclear charges. Thus an antinucleus must have the same mass as the nucleus. And this means that the nuclear “binding” masses obey CPT invariance. The mass of the deuteron has in its value all transition processes needed for the QCD colour-full world of quarks and gluons to become the world made of mesons and baryons. The equality of the “binding” masses in nuclei and antinuclei is the proof that CPT invariance holds in all these processes.
