| dc.description | We calculate the production of massive Kaluza-Klein(KK) modes via nucleon-nucleon gravi-bremsstrahlung in the early universe. Overproduction of these states would result in early matter domination and therefore a low age for the universe so it is possible to place constraints on the number and size of large extra dimensions. The constraints are stronger than those from Sn1987a - for 2 large extra dimensions and T_QCD=170 MeV, we show the fundamental scale must be larger than 1,000 TeV. | |
