Thanks @David Zaslavsky, hm maybe Ill try. Although Im not quite sure if this would really answer my question. I just wanted to explain (to Anna) what I think I have understood from Lenny Susskind about the winding modes to clarify the question a bit. Maybe this edit was not too good and it earned me the retraction of the upvote :-/ ...?

| Jan 15, 2012 at 21:41 | comment | added | Dilaton | Now the link works :-). I`ve just found a picture of the spectra of the KK and the winding modes: web.me.com/kenmcelvain/StringTheory/StringTheory_C9_files/…. If I understand this right they both correspond to particles which are similar to but more massive than the known particles. The "extra mass" is due to the kinetic energy of the movement IN the extra dimensions for the KKs or due to the additional stretching potential energy for the winding modes which are wound AROUND, dependent on the size of the extra dimensions. | |

| Jan 15, 2012 at 21:16 | comment | added | anna v | But are winding modes particles necessarily? The first link is from a search of the CERN preprints. cdsweb.cern.ch/collection/Articles%20%26%20Preprints?ln=en asking for "extra dimensions LHC" | |

which leads to step size to be proportional to r. The winding modes and the KKs are T-dual to each other. Ive stolen this from Prof. Susskind's lectures :-). So Im aking myself if the winding particles should start being more easy to get (if they exist) if there are strong limits for the size of the extra dimensions ...?

| Jan 15, 2012 at 14:39 | comment | added | Dilaton | Thanks @anna v. There seems to be something wrong with the first link; upon clicking it says "Collection Articles Not Found". Considering an extra dimension that is much larger than the particle, the heavier KK modes with the 1/r spectrum arise from the quantized angular momentum a particle can have in the extra dimension. If the extra dimension is smaller the particle can wind around the extra dimension leading to the winding mode particles (if they are not points ... ;-P). For these these the energy spectrum is determined by the potential stretching energy | |
