Magnetic Moments of Heavy Baryons
First non-trivial chiral corrections to the magnetic moments of triplet (T ) and sextet (S(∗)) heavy baryons are calculated using Heavy Hadron Chiral Perturbation Theory. Since magnetic moments of the T -hadrons vanish in the limit of infinite heavy quark mass (mQ → ∞), these corrections occur at order O(1/(mQΛχ)) for T -baryons while for S(∗)-baryons they are of order O(1/Λχ). The renormalizat...
متن کاملHigher Moments of Heavy Quark Vacuum Polarization
We present analytical calculation of the first seven moments of the heavy quark vacuum polarization function in the three-loop order. The obtained results are compared against the asymptotic formulas following from the threshold singulari-ties. We also discuss the µ dependence of the moments within the BLM procedure.

متن کاملLarge electric dipole moments of heavy leptons.
In many models of CP violation, the electric dipole moment (EDM) of a heavy charged or neutral lepton could be very large. In models in which the EDMs scale as the cube of the mass, as well as in vectorlike models, a 100 GeV heavy lepton can have an EDM as large as 0.01e fermi. This could dominate the electromagnetic properties of heavy leptons. The angular distribution and production cross sec...
متن کاملLepton Electric Dipole Moments from Heavy States Yukawa Couplings
In supersymmetric theories the radiative corrections due to heavy states could leave their footprints in the flavour structure of the supersymmetry breaking masses. We investigate whether present and future searches for the muon and electron EDMs could be sensitive to the CP violation and flavour misalignment induced on slepton masses by the radiative corrections due to the right-handed neutrin...
