What is Electromagnetic Dipole Moments of the Top Quark about?

Recent measurements like the t tbar gamma production by CDF as well as the Br(B ->Xs gamma) and ACP (B->Xs gamma) are used to constrain the magnetic and electric dipole moments of the top quark. The B->Xs gamma measurements by themselves define an allowed parameter region that sets up stringent constraints on both dipole moments. Actually, significantly more stringent than previously reported. The measurement by CDF has a 37% error that is too large to set any competitive bounds, for which a much lower 5% error would be required at least. On the other hand, because of the LHC's higher energy (apart from its higher luminosity) the same measurement performed there could indeed further constrain the allowed parameter region given by the B->Xs gamma measurement.
