We consider the NLS equation with combined power-type nonlinearities in the mass-subcritical regime, where a focusing leading term is perturbed by a lower order defocusing term, and we prove small data scattering. The proof relies on the pseudo-conformal transformation in conjunction with a general variational argument used to obtain the positivity of certain modified energies. The smallness assumption is only on the mass of the initial datum, and not on the whole Σ-norm. This is a joint work with J. Bellazzini and V. Georgiev.
