  We introduce superconducting proximity effects in Weyl semi-metals (WSM) with
broken time reversal symmetry by tunnel coupling one of its surfaces to an
s-wave superconductor using the Green's function approach. We find that the
band structure develops coherence peaks, but despite the presence of metallic
states in the bulk, the coherence peaks do not extend far into the bulk and
remain confined to a few layers close to the interface, similar to the
proximity effect in the topological insulators (TI) which are gapped in the
bulk. The Weyl nodes remain unaffected, and in that sense, no true gap
develops. We also study the various induced p and s-wave pairing amplitudes
classified by their symmetries, as a function of the various relevant
parameters of the theory and note the exponential decay of the induced pairings
in the bulk both in the TI and the WSM, even at finite chemical potential.
