Running of the Spectral Index as a Probe of Physics at High Energy
The WMAP results on the scalar spectral index n and its running with scale, though preliminary, open a very interesting window to physics at very high energies. We address the problem of finding simple inflaton potentials, well motivated by particle physics, that can accommodate WMAP data.
