Abstract
We consider the worldsheet boundary scattering and the corresponding boundary algebras for the Z=0 giant graviton and the Z=0 D7brane in the AdS/CFT correspondence. We consider two approaches to the boundary scattering, the usual one governed by (generalized) twisted Yangians and the qdeformed model of these boundaries governed by quantum affine coideal subalgebras. We show that the qdeformed approach leads to boundary algebras that are of a much more compact form than the corresponding twisted Yangians, and thus are favourable to use for explicit calculations. We obtain the qdeformed reflection matrices for both boundaries which in the q\rightarrow1 limit specialize to the ones obtained using twisted Yangians.
