Bethe vectors of GL(3)-invariant integrable models

Understand

We study SU(3)-invariant integrable models solvable by nested algebraic Bethe ansatz.

• Different formulas are given for the Bethe vectors and the actions of the generators of the Yangian Y(sl(3)) on Bethe vectors are considered.
• These actions are relevant for the calculation of correlation functions and form factors of local operators of the underlying quantum models.
