A New Model-independent Method for Extracting Spin-dependent Cross Section Limits from Dark Matter Searches
نویسنده
چکیده
A newmethod is proposed for extracting limits on spin-dependent WIMP-nucleon interaction cross sections from direct detection dark matter experiments. The new method has the advantage that the limits on individual WIMP-proton and WIMP-neutron cross sections for a givenWIMP mass can be combined in a simple way to give a model-independent limit on the properties of WIMPs scattering from both protons and neutrons in the target nucleus. Extension of the technique to the case of a target material consisting of several different species of nuclei is discussed. PACS: 95.35.+d; 12.60.Jv; 14.80.Ly

Blind Spots for Direct Detection with Simplified DM Models and the LHC
Using the existing simplified model framework, we build several dark matter models which have suppressed spin-independent scattering cross section. We show that the scattering cross section can vanish due to interference effects with models obtained by simple combinations of simplified models. For weakly interacting massive particle (WIMP) masses &10 GeV, collider limits are usually much weaker...
متن کاملSpin-dependent WIMP limits from a bubble chamber.
Bubble chambers were the dominant technology used for particle detection in accelerator experiments for several decades, eventually falling into disuse with the advent of other techniques. We report here on a new application for these devices. We operated an ultraclean, room-temperature bubble chamber containing 1.5 kilograms of superheated CF3I, a target maximally sensitive to spin-dependent a...
متن کاملThe Potential Impact of a CF3I-based Superheated Droplet Detector in Searches for WIMP Dark Matter
Limits on weakly interacting massive particle dark matter obtainable from a Superheated Droplet Detector loaded with CF3I as active material are estimated on the basis of the radiopurity levels already achieved by the SIMPLE experiment. With 15 kgd exposure, such an experiment may already probe to 10−6 pb in the spinindependent cross section; for the case of spin-dependent WIMPs, the region of ...
متن کاملOn possible lower bounds for the direct detection rate of SUSY Dark Matter
One can expect accessible lower bounds for dark matter detection rate due to restrictions on masses of the SUSY-partners. To explore this correlation one needs a new-generation large-mass detector. The absolute lower bound for detection rate can naturally be due to spin-dependent interaction. Aimed at detecting dark matter with sensitivity higher than 10 event/day/kg an experiment should have a...
متن کاملLimits on Momentum-Dependent Asymmetric Dark Matter with CRESST-II.
The usual assumption in direct dark matter searches is to consider only the spin-dependent or spin-independent scattering of dark matter particles. However, especially in models with light dark matter particles O(GeV/c^{2}), operators which carry additional powers of the momentum transfer q^{2} can become dominant. One such model based on asymmetric dark matter has been invoked to overcome disc...
