Abstract:
We derive the part of the Lagrangian for the sigma model on the
η
-deformed

space which is quadratic in fermions and has the full dependence on bosons.
We then show that there exists a field redefinition which brings the corresponding La-
grangian to the standard form of type IIB Green-Schwarz superstring. Reading off the
corresponding RR couplings, we observe that they fail to satisfy the supergravity equa-
tions of motion, despite the presence of
κ
-symmetry. However, in a special scaling limit
our solution reproduces the supergravity background found by Maldacena and Russo. Fur-
ther, using the fermionic Lagrangian, we compute a number of new matrix elements of the
tree level world-sheet scattering matrix. We then show that after a unitary transformation
on the basis of two-particle states which is
not one-particle factorisable
, the corresponding
T-matrix factorises into two equivalent parts. Each part satisfies the classical Yang-Baxter
equation and coincides with the large tension limit of the
q
-deformed S-matrix.
