Diagonalization of the neutralino mass matrix and boson-neutralino interaction

High Energy Physics - Phenomenology 2014-11-18 v3

Abstract

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.
