Effective field theory analysis of composite higgsino-like and wino-like thermal relic dark matter

We study the effective field theory (including operators up to dimension five) of models in which dark matter is composite, consisting either an electroweak doublet Dirac fermion (`higgsino-like matter') or triplet Majorana (`wino-like matter'). Some dimension-five former case cause mass splittings between neutralino and chargino states, leading a depleted rate coannihilations viable thermal relic with masses order tens hundreds GeV rather than usual pure higgsino 1 TeV. No such effects are found latter (where 3 TeV). Other operators, present for both wino- higgsino-like matter, correspond inelastic electromagnetic dipole moment interactions annihilation through these can lead by magnitude compared values.
