چکیده
Recently two interesting conjectures about the string S-matrix on AdS 5 × S 5 have been made. First, assuming the existence of a Hopf algebra symmetry Janik derived a functional equation for the dressing factor of the quantum string Bethe ansatz. Second, Hernández and López proposed an explicit form of 1/ √ λ correction to the dressing factor. In this note we show that in the strong coupling expansion Janik's equation is solved by the dressing factor up to the order of its validity. This observation provides a strong evidence in favor of a conjectured Hopf algebra symmetry for strings in AdS 5 ×S 5 as well as the perturbative string S-matrix.

We first analyze the spinning string in the magnetic field deformed AdS5×S spacetime which was constructed in our previous paper. It is seen that the associated effective Lagrangian of string sigma model describes the spin chain model with magnetic field, in which the corresponding spin vector has been properly deformed and is living on the deformed S. The mechanism of spin deformation is descr...

We construct a family of closed string solutions with kinks in a subspace of AdS5 × S and study their properties. In certain limits these solutions become folded pulsating strings, although in general they are made of multiple pulsating rectangles. One unusual feature of these solutions is that their monodromy matrices are trivial, leading to vanishing quasi-momenta. Exact Bäcklund transformati...

متن کاملA large spin limit of strings on AdS 5 × S 5 in a non - compact sector
We study the scaling law of the energy spectrum of classical strings on AdS5 × S, in particular, in the SL(2) sector for large S (AdS spin) and fixed J (S ⊂ S spin). For any finite gap solution, we identify the limit in which the energy exhibits the logarithmic scaling in S, characteristic to the anomalous dimension of low-twist gauge theory operators. Our result therefore shows that the logS s...
