We analyze the effects of $\mathrm{CP}$-violating phases on the electric dipole moment (EDM) of the electron and neutron in the constrained minimal supersymmetric model. We find that the phases ${\ensuremath{\varphi}}_{\ensuremath{\mu}}$ and ${\ensuremath{\varphi}}_{{A}_{0}}$ have to be strongly correlated, in particular for small values of the SUSY mass parameters. We calculate the neutron EDM in two different models, the quark-parton model and the chiral quark model. It turns out that the…

Neutralino exchange corrections to the Higgs boson mixings with explicit CP violation

A calculus for the derivatives of the eigenvalues of the neutralino mass matrix with respect to the $\mathrm{CP}$ violating background fields is developed and used to compute the mixings among the

CP sensitive observables in chargino production and decay into a W boson

We study $CP$ sensitive observables in chargino production in electron-positron collisions with subsequent two-body decay of one chargino into a $W$ boson. We identify the $CP$ odd elements of the

Reconciling large CP-violating phases with bounds on the electric dipole moments in the MSSM

The possibility of cancellation between different contributions to d{sub e}, d{sub n} and d{sub Hg} is reconsidered with special emphasis on the region that is phenomenologically interesting

We show that EDMs obey a simple approximate scaling under the transformation

Systematic study of the impact of CP-violating phases of the minimal supersymmetric standard model on leptonic high-energy observables

Low-energy results from measurements of leptonic dipole moments are used to derive constraints on the CP-violating phases of the dimensionful parameters of the minimal supersymmetric extension of the

Measurement of CP violation in stop cascade decays at the LHC

AbstractWe study the potential observation at the LHC of CP-violating effects in stop production and subsequent cascade decays, $gg\to \tilde{t}_{i}\tilde{t}_{i}$ , $\tilde{t}_{i}\to

Hadronic electric dipole moments in R-parity violating supersymmetry

We calculate the electric dipole moments (EDM) of the neutral {sup 199}Hg atom, neutron and deuteron within a generic R-parity violating SUSY model (Re{sub p} SUSY) on the basis of a

CP violation and the muon anomaly in N=1 supergravity

The one loop supersymmetric electro-weak correction to the anomalous magnetic moment of the muon is derived in the minimal N=1 supergravity unification with two CP violating phases. A numerical

Testing the CP-violating MSSM in stau decays at the LHC and ILC

We study $CP$ violation in the two-body decay of a scalar tau into a neutralino and a tau, which should be probed at the LHC and ILC. From the normal tau polarization, a $CP$ asymmetry is defined
