Photonic two-loop corrections to (g-2)_μ in the MSSM

Weitershausen, Philipp von; Stoeckinger, Dominik; Stoeckinger-Kim, Hyejung; Schaefer, Marco2009

[en] The discrepancy between experiment and Standard Model predictions makes the muon's anomalous magnetic moment (g-2)_μ a promising contender for the search of BSM physics. In this talk we look at a selection of MSSM two-loop processes contributing to (g-2)_μ. The discussed set of diagrams comprises MSSM one-loop diagrams to which a photon loop has been added, featuring characteristic logarithms

Selected oblique two-loop corrections to (g-2)_μ in the MSSM

Schaefer, Marco; Stoeckinger, Dominik; Stoeckinger-Kim, Hyejung; Weitershausen, Philipp von2009

AbstractAbstract

[en] We have calculated selected two-loop diagrams contributing to the muon anomalous magnetic moment in the Minimal Supersymmetric Standard Model. These are chargino or neutralino one-loop diagrams with an additional third generation squark or squark-quark loop. Such diagrams exhibit oblique corrections as in the Standard Model and typically contain m_top and m_bottom. We will describe our methods of calculation and renormalization as well as numerical evaluation of SUSY parameters

Energy-momentum tensors with worldline numerics

Schaefer, Marco; Gies, Holger; Huet Hernandez, Idrish2011

AbstractAbstract

[en] We apply the worldline formalism and its numerical Monte-Carlo approach to computations of fluctuation induced energy-momentum tensors. In the case of a fluctuating Dirichlet scalar this formalism allows the computation of induced energy-momentum tensors in arbitrary Casimir configurations. Our methods can straightforwardly be used to investigate potential violations of positive-energy conditions by quantum field theories. These energy conditions are of particular interest in General Relativity where they are imposed on the energy-momentum tensor in order to avoid exotic spacetime properties.
