Implications on inelastic dark matter from 100 live days of XENON100 data

The XENON100 experiment has completed a dark matter search with 100.9 live days of data, taken from January to June 2010. Events with energies between 8.4 and $44.6\text{ }\text{ }{\mathrm{keV}}_{\mathrm{nr}}$ in a fiducial volume containing 48 kg of liquid xenon have been analyzed. A total of three events have been found in the predefined signal region, compatible with the background prediction of ($1.8\ifmmode\pm\else\textpm\fi{}0.6$) events. Based on this analysis we present limits on the WIMP-nucleon cross section for inelastic dark matter. With the present data we are able to rule out the explanation for the observed DAMA/LIBRA modulation as being due to inelastic dark matter scattering off iodine, at a 90% confidence level.
