Abstract / Description:We show that for a neutrino factory baseline of $L \sim 7300 km - 7 600 km$ a
"clean" measurement of $\sin^2 2 \theta_{13}$ becomes possible, which is almost
unaffected by parameter degeneracies. We call this baseline "magic" baseline,
because its length only depends on the matter density profile. For a complete
analysis, we demonstrate that the combination of the magic baseline with a
baseline of 3000 km is the ideal solution to perform equally well for the
$\sin^2 2 \theta_{13}$, sign of $\Delta m_{31}^2$, and CP violation
sensitivities. Especially, this combination can very successfully resolve
parameter degeneracies even below $\sin^2 2 \theta_{13} < 10^{-4}$.
