We analyze a connection between neutralino mass sign, parity and structure of the neutralino-boson interaction. Correct calculation of spin-dependent and spin-independent contributions to neutralino-nuclear scattering should consider this connection. A convenient diagonalization procedure, based on the exponetial parametrization of unitary matrix, is suggested.

    In supersymmetric DFSZ axion models, the LHC with 140 fb^{-1} can probe axion decay constants below 10^{11} GeV for higgsino masses under 1 TeV via displaced neutralino decays to axino LSPs.
