We demonstrate that two-dimensional two-component bright solitons of an annular shape, carrying vorticities (m,±m) in the components, may be stable in media with the cubic-quintic nonlinearity, including the hidden-vorticity (HV) solitons of the type (m,−m), whose net vorticity is zero. Stability regions for the vortices of both (m,±m) types are identified for m=1, 2, and 3, by dint of the calculation of stability eigenvalues, and in direct simulations. In addition to the well-known...[Show more]
