If we find extra dimensions in the second run of the LHC in the pp collisions at √(s) = 14 TeV, then the string mass scale Ms can be ∼ TeV and we should produce QCD jets in 2 → 2 partonic collisions via string Regge excitations at the LHC. QCD jets can also be produced from string balls via thermal radiation at Hagedorn temperature. In this paper we study jet production from string Regge excitations vs string balls in pp collisions at √(s) = 14 TeV at LHC and make a comparison with the standard model QCD jets. We find that high pT jet production from string Regge excitations can be larger than that from string balls and from standard model QCD jets. We also find resonances in the jet production cross section in string Regge excitation scenario which is absent in the other two scenarios. Hence TeV scale high pT jets can be a good signature to study string Regge excitations in the pp collisions at √(s) = 14 TeV at the LHC.
