115. See Table 24.1 in W.M. Yao (Particle Data Group), J. Phys. G JPGPED 0954-3899 33, 1 (2006). 10.1088/0954-3899/33/1/001
116. The ratio of ∼100 is taken from Table 24.1 of W.M. Yao, Ref., and is at an energy of 10.4GeV/nucleon. This ratio is expected to extrapolate to higher energies as long as the cosmic rays are trapped in the Galaxy, perhaps up to 10TeV/nucleon. In order to account for the HEGRA data, the accelerative process requires injection from the nuclei population at energies 2-3 orders of magnitude lower than 1PeV/nucleon [see discussion following Eq. 23], where we expect this ratio to hold.

148. It is worth noticing that the ν̄ β-beam provides a unique discriminator of very long baseline neutrino-mixings, and therefore can serve as a extremely sensitive probe of new physics in the electroweak sector.
