On Supersymmetric Effective Theories of Axion

By Tetsutaro Higaki and Ryuichiro Kitano

Abstract

We study effective theories of an axion in spontaneously broken supersymmetric theories. We consider a system where the axion supermultiplet is directly coupled to a supersymmetry breaking sector whereas the standard model sector is communicated with those sectors through loops of messenger fields. The gaugino masses and the axion-gluon coupling necessary for solving the strong CP problem are both obtained by the same effective interaction. We discuss cosmological constraints on this framework.Comment: 41 pages, 3 figures, 2 tables; v2 additional comments and reference
