Description
If Supersymmetry were realized in Nature, it ought to have been broken at a high scale during inflation. Indirect signs of this epoch have shown up in the results of the Planck satellite, which have provided evidence for a non-trivial CMB spectral tilt ns<1. I elaborate on models on "brane supersymmetry breaking", a peculiar and natural mechanism drawn from String Theory, to investigate whether the lack of power in the low-l CMB might be telling us something about the onset of inflation.
