EFT Recoil Spectra Shaun Alsum 2017/08/01
Based on arXiv:1203.3542 (Fitzpatrick, Haxton, Katz, Lubbers, Xu) • Anand, Fitzpatrick, Haxton wrote a mathematica package to determine rates in DM searches (arXiv:1308.6288) • Options for DM spin, halo type, target material, etc.
Give it a try! • compared several operators Relative Rate Recoil Energy (keV) Neutrons only, DM spin 1, Xe131 only Seems like they all die off at 140 keV
A Few Questions… O1 Spectra Ratio of 0.0218 at 50 keV What about neutron-proton interference? See above, for instance (C n 1 =1, C p 1 =-1)
Questions continued… • What spin are we assuming for DM? • Why? • Should we do all sorts?
