Hadron Electric Dipole Moments from CP-Odd Operators of Dimension Five Via QCD Sum Rules: The Vector Meson
Maxim Pospelov, Adam Ritz
We present a complete analysis of the electric dipole moment (EDM) of the ρ-meson induced by CP violating operators of dimension 4 and 5 within the QCD sum rules approach. The set…
Instantons at Strong Coupling, Averaging over Vacua, and the Gluino Condensate
Adam Ritz, Arkady Vainshtein
We consider instanton contributions to chiral correlators, such as <0| Tr λ^2 (x) Tr λ^2(x') |0>, in N=1 supersymmetric Yang-Mills theory with either light adjoint or fundamental m…
Theta Vacua, QCD Sum Rules, and the Neutron Electric Dipole Moment
Maxim Pospelov, Adam Ritz
We present a detailed study of the electric dipole moment of the neutron induced by a vacuum theta angle within the framework of QCD sum rules. At next-to-next-to leading order in…
A Note on Classical String Dynamics on AdS_3
Maximo Banados, Adam Ritz
We consider bosonic strings propagating on Euclidean adS_3, and study in particular the realization of various worldsheet symmetries. We give a proper definition for the Brown-Henn…
Theta-Induced Electric Dipole Moment of the Neutron via QCD Sum Rules
M. Pospelov, A. Ritz
Using the QCD sum rule approach, we calculate the electric dipole moment of the neutron induced by a vacuum theta--angle to approximately 40-50% precision, d_n = 2.4 x 10^{-16} θe.…
Geometric Phase Transitions
D. C. Brody, A. Ritz
A model in statistical mechanics, characterised by the corresponding Gibbs measure, is a subset of the totality of probability distributions on the phase space. The shape of this s…
