### Theory Update 113

Under the assumption that neutrinos are tachyonic, while the ordinary antineutrinos are not, the $\overline{\nu}$ may travel at a speed very close to $c$. Then the $\Delta v / c$ measured by OPERA would characterise the difference between canonical speeds for the two species. The simple formula given by number 26 is then rewritten

$\frac{\Delta v}{c} = (26^{\textrm{log} 26})^{-1} = 2.45 \times 10^{-5}$

where as usual $26$ is the dimension of bosonic strings, namely the traceless elements of the $3 \times 3$ octonion Jordan algebra.

1. It seems likely, however, that local antineutrinos also travel at a speed distinct from $c$, giving a triplet of quantized speeds $(v_1, c, v_2)$.
