  We present a theoretical analysis of the shot noise in d-wave/d-wave contacts
with arbitrary transparency, including the contribution of multiple Andreev
reflections. The multiple charge quanta transferred in these processes are
revealed as a huge enhancement of the noise-current ratio at low voltages,
which survives for all crystal misorientations. We also show how different
ingredients like non-magnetic impurities or a magnetic field produce very
characteristic hallmarks in the shot noise, which can be used as a further test
of the d-wave scenario in superconducting cuprates.
