q-deformed su(2|2) boundary S-matrices via the ZF algebra

Abstract

Beisert and Koroteev have recently found a bulk S-matrix corresponding to a q-deformation of the centrally-extended su(2|2) algebra of AdS/CFT. We formulate the associated Zamolodchikov-Faddeev algebra, using which we derive factorizable boundary S-matrices that generalize those of Hofman and Maldacena.Comment: 15 pages; v2: correct misplaced equation labe
