The invention of supersymmetry, almost exactly 25 years ago,1 changed the face of high energy physics. The idea that the observed low energy gauge groups appear due to the process of spontaneous breaking of a single unifying group G is also quite popular. The synthesis of these two elements results in supersymmetric grand unification. I present (perturbatively) exact results regarding the supersymmetric evolution of the gauge couplings from the scale of their unification to lower scales. In particular, it is shown how the heavy mass thresholds can be properly taken into account to all orders.

Low energy antiprotons are available for physics experiments at CERN since the 1980s and have been used by a large variety of experiments. The Low Energy Antiproton Ring LEAR has been constructed as a complementary use of antiprotons available at that time for high energy physics and delivered beam to experiments mainly using slow extraction. After completion of LEAR exploitation, the Antiproton Decelerator (AD) was constructed (adaptation of the existing Antiproton Collector, AC) to allow for a simpler low energy antiproton scheme (only one accelerator operated with Antiprotons) with fast extraction well suited for trap experiments. The Extra Low ENergy Antiproton ring ELENA is a small synchrotron presently constructed to further decelerate antiprotons from the AD in a controlled manner, and to reduce emittances with the help of an electron cooler to improve the capture efficiencies of existing experiments and allow for additional ones.

We collect and estimate support for our long speculated “multiple point principle”[Formula: see text] saying that there should be several vacua all having (compared to the scales of high energy physics) very low energy densities. In pure Standard Model, we suggest there being three “multiple point principle” low energy density vacua, “present,” “condensate” and “high field” vacuum. We fit the mass in our picture of a long speculated bound state[Formula: see text] of 6 top and 6 antitop quarks in three quite independent ways and get remarkably within our crude accuracy the same mass in all three fits! The new point of the present paper is to estimate the bound state mass in what we could call a bag-model estimation. The two other fits, which we review, obtain the mass of the bound state by fitting to the multiple point principle prediction of degenerate vacua. Our remarkable agreement of our three mass-fits can be interpreted to mean that we have calculated at the end the energy densities of the two extra speculated vacua and found that they are indeed very small. Unfortunately, the recently much discussed statistical fluctuation peak F(750)[Formula: see text] that has now been revealed to be just a fluctuation, very accidentally matches our fitted mass of the bound state remarkably well with the mass of this fluctuation 750 GeV.
