... While the existence of neutrinos associated with the tau lepton was not in doubt, actually observing the particle interact had not occurred until now. This rounds out the program of experimental sightings of the truly fundamental building blocks prescribed by the standard model of particle physics. ... The detection of the electron neutrino by Clyde Cowan and Frederick Reines garnered Reines the 1995 Nobel Prize for physics (Cowan had died some years before). ...
EXTRA INVISIBLE DIMENSIONS are for particle physicists what they are for Star Trek captains: a device for covering a lot of ground quickly and explaining anomalous behavior. In physics the importation of extra dimensions into the standard theory helps to make peace between quantum mechanics and general relativity, but it doesnt explain the great disparity (the "hierarchy problem") between the temperature at which the weak and electromagnetic forces fuse together (102 GeV, expressed in energy units) and the temperature at which gravity joins up with the other forces (1018 GeV), a temperature so hot, or an energy so high, that such conditions have not prevailed since a tiny moment after the big bang. ... This in turn would allow GUT physics to be observed directly in the next round of accelerator experiments. ... Once an elementary particle, such as a Z boson (one of the particles carrying the weak force), is accelerated to TeV-scale energies, its "Compton wavelength" (the size of the Z as a wavelike object) will become smaller than the extra dimension and it can essentially "fall into" and rattle around inside the extra dimension.
