Query: One Bump or Two Peaks? The 750 GeV Diphoton Excess and Dark Matter with
  a Complex Mediator   We consider the possibility that the recently observed excess in the diphoton
invariant mass spectrum around 750 GeV is due to two narrow scalars. We
demonstrate that there is no need to introduce invisible decay modes to enlarge
the widths as long as the two scalars exhibit an appropriate mass splitting.
Nevertheless we investigate the possible connection of these two scalars to the
dark matter in a toy model with a Majorana fermionic dark matter candidate. We
explore how large the widths of the two scalar widths could be taking into
account various constraints from collider and dark matter experiments.
Introducing two scalars alleviates the tension between the diphoton production
and dark matter constraints.
