P-odd and CP-odd four-quark contributions to neutron EDM

The b–quark EDM in SUSY and CP–odd bottomonium formation

We compute the electric dipole moment (EDM) of the bottom quark in minimal supersymmetric model (SUSY) with explicit CP violation. We estimate its upper bound to be 10 e− cm where the dominant contribution comes from the charginos for most of the SUSY parameter space. We also find that chargino contribution is directly correlated with the branching fraction of the B → Xsγ decay. Furthermore, we...

Mixing of the CP Even and the CP Odd Higgs Bosons and the EDM Constraints

The mixing among the CP even and the CP odd neutral Higgs bosons of MSSM by one loop induced effects in the presence of CP phases is investigated using three different mechanisms to satisfy the EDM constraints, i.e., a fine tuning of phases, a heavy sparticle spectrum, and the cancellation mechanism. It is shown that if a mixing effect among the CP even and the CP odd Higgs bosons is observed e...

CP-odd Higgs in NMSSM

We study the sensitivity of rare decay π → e+e− to the light CP-odd Higgs A01 in the NMSSM. It is shown that the 3.3σ discrepancy between theoretical prediction and the recent KTeV measurement of B(π0 → e+e−) can be resolved with two narrow bands of NMSSM parameter space. For mA0 1 = 214.3 MeV, i.e., A01 as the state in Σ + → pμ+μ− decay found by HyperCP Collaboration, π → e+e− constrains |Xd| ...

Shapes of neutron - rich A ≈ 190 odd - odd nuclei

Following from the prediction by Hilton and Mang [1] of “giant backbending” in 180Hf, caused by a collective oblate rotational band crossing the prolate ground-state band, there has been further theoretical investigation of this phenomenon [2–5]. The calculated shape change is understood to be induced by the effects of rotation alignment. It is related to the prediction of a ground-state shape ...
