Matters on a moving brane

Understand

A novel generalisation of the Dirac-Born-Infeld string scenario is described.

• It is shown that matter residing on the moving brane is dark and has the so-called disformal coupling to gravity.
• This gives rise to cosmologies where dark matter stems from the oscillations of the open strings along the brane and the transverse oscillations result in dark energy.
• Furthermore, due to a new screening mechanism that conceals the fifth force from local experiments, one may even entertain the possibility that the visible sector is also moving along the extra dimensions.
