text: The distribution of Coulomb blockade peak heights as a function of magnetic
field is investigated experimentally in a Ge-Si nanowire quantum dot. Strong spin-orbit
coupling in this hole-gas system leads to antilocalization of Coulomb blockade
peaks, consistent with theory. In particular, the peak height distribution has
its maximum away from zero at zero magnetic field, with an average that decreases
with increasing field. Magnetoconductance in the open-wire regime places a bound
on the spin-orbit length (lso < 20 nm), consistent with values extracted in the
Coulomb blockade regime (lso < 25 nm).
