Time varying gauge couplings and di-nucleon states
  In this talk we discuss the effect upon the di-proton, di-neutron and deuteron of a time variation of the QCD gauge coupling. We describe how a time evolution of the size of extra dimensions can give rise to such a variation and show how this is related to the recent results on possible time variation of the electromagnetic fine structure constant. Based on work in collaboration with Tom Dent.
