Direct and indirect constraints on isospin-violating dark matter

The scenario of isospin-violating dark matter (IVDM) with destructive interference between DM-proton and DM-neutron scatterings provides a potential possibility to reconcile the experimental results of DAMA, CoGeNT and XENON. We explore the constraints on the IVDM from other direct detection experiments such as CRESST and SIMPLE, etc. and from the indirect DM searches such as the antiproton flux measured by BESS-Polar II. The results show that the relevant couplings in IVDM scenario are severely constrained.
