Abstract: We show that if a flavour-less vector meson remains bound after deconfinement, and if its limiting velocity in the quark-gluon plasma is subluminal, then this meson produces a distinct peak in the spectrum of thermal photons emitted by the plasma. We also demonstrate that this effect is a universal property of all strongly coupled, large- plasmas with a gravity dual. For the the corresponding peak lies between 3 and 5 GeV and could be observed at the LHC. [Copyright &y& Elsevier]
