Feasibility of perturbative generation of bound states from resonances or virtual states
Original language description
I investigate whether it is possible to generate bound states from resonances or virtual states through first-order perturbation theory. Using contact-type potentials as those appeared in pionless effective field theory, I show that it is possible to obtain negative-energy states by sandwiching a next -to -leading order interaction with the leading-order (LO) wave functions, under the presence of LO resonances or virtual states. However, at least under the framework of time -independent Schrodinger equation and Hermitian Hamiltonian, there is an inability to create bound states with structure similar to those formed by the nonperturbative treatments.
