Direct and indirect limits on the electro-magnetic form factors of WIMPs

Abstract We use the results of direct and indirect searches for weakly interacting massive particles (WIMPs) to obtain bounds on various electro-magnetic form factors of WIMPs. The limits on the recoil signal in underground dark matter detection experiments, with standard assumptions about the density and r.m.s. velocity of WIMPs in the halo, can be translated into the following model-independent bounds on the magnetic dipole, electric dipole, quadrupole and anapole moments and the polarizability of WIMPs: μ/μn d −21 e cm , Q −7 fm 2 , a/μ n −2 fm , and χ −8 fm 3 for a WIMP mass of 100 GeV. The limits on fluxes of highly energetic neutrinos produced in the annihilation of WIMPs in the center of the earth and the sun lead to somewhat stronger, but more model dependent bounds.

Domain wall junctions in a generalized Wess-Zumino model.

Abstract We investigate domain wall junctions in a generalized Wess-Zumino model with a Z N symmetry. We present a method to identify the junctions that are potentially BPS saturated. We then use a numerical simulation to show that those junctions indeed saturate the BPS bound for N=4. In addition, we study the decay of unstable non-BPS junctions.
