Dirac Gauginos and Kinetic Mixing
We present formulae for the calculation of Dirac gaugino masses at leading order in the supersymmetry breaking scale using the methods of analytic continuation in superspace and demonstrate a link with kinetic mixing, even for non-abelian gauginos. We illustrate the result through examples in field and string theory. We discuss the possibility that the singlet superfield that gives the U(1) gau...
متن کاملKinetic Mixing and the Supersymmetric Gauge Hierarchy
The most general Lagrangian for a model with two U(1) gauge symmetries contains a renormalizable operator which mixes their gauge kinetic terms. Such kinetic mixing can be generated at arbitrarily high scales but will not be suppressed by large masses. In models whose supersymmetry (SUSY)breaking hidden sectors contain U(1) gauge factors, we show that such terms will generically arise and commu...
متن کاملBrane - Antibrane Kinetic Mixing , Millicharged Particles and SUSY Breaking
It is known that hidden U(1) gauge factors can couple to visible U(1)'s through Kinetic Mixing. This phenomenon is shown generically to occur in nonsuper-symmetric string setups , between D-branes and D-branes. Kinetic Mixing acts either to give millicharges (of e.g. hypercharge) to would-be hidden sector fermions, or to generate an enhanced communication of supersymmetry breaking that dominate...
متن کاملCosmic Rays from Leptophilic Dark Matter Decay via Kinetic Mixing
If interpreted in terms of decaying dark matter, the steep rise in the positron fraction of cosmic rays above 10GeV, as observed by the PAMELA experiment, suggests an underlying production mechanism that favors leptonic channels. We consider a scenario where a portion of the dark matter is made of the gauginos of an unbroken hidden-sector U(1)X , which interact with the visible sector only thro...
متن کاملThe kinetic depth effect.
The problem of how three-dimensional form is perceived in spite of the fact that pertinent stimulation consists only in two-dimensional retinal images has been only partly solved. Much is known about the impressive effectiveness of binocular disparity. However, the excellent perception of threedimensional form in monocular vision has remained essentially unexplained. It has been proposed that s...
