Query: Vacuum energy, Standard Model physics and the $750\; \rm{GeV}$ Diphoton
  Excess at the LHC   The conditions for the cancellation of one loop contributions to vacuum
energy (both U.V. divergent and finite) coming from the known (Standard Model)
fields and the field associated with the hypothetical 750 Gev diphoton excess
are examined. Depending on the nature of this latter resonance we find that in
order to satisfy the constraints (sum rules) different additional, minimal
field contributions are required, leading to yet to be observed particles.
