In five or six dimensional orbifold GUTs, on the other hand,the ?GUT scale? threshold correction comes from the Kaluza-Klein modes between thecompactification scale, Mc, and the effective cutoff scale M?.6Thus, in orbifold GUTs,gauge ...

With higher statistics, isolation of lowest massive Regge excitations from Kaluza-Klein replicas (with J=2) may also be possible. Four-fermion channels were used previously to obtain model-dependent bounds on Ms. ...
