  The separation of the Weyl nodes in a broken time-reversal symmetric Weyl
semimetal leads to helical quasi-particle excitations at the Weyl nodes, which,
when coupled with overall spin conservation allows only inter-nodal transport
at the junction of the Weyl semimetal with a superconductor. This leads to an
unusual periodic oscillation in the Josephson current as a function of $k_0L$,
where $L$ is the length of the Weyl semimetal and $2k_0$ is the inter-nodal
distance. This oscillation is robust and should be experimentally measurable,
providing a direct path to confirming the existence of chiral nodes in the Weyl
semimetal.
