Quantum mechanics says there is a wavefunction. How you choose to interpret that wavefunction in terms of particles (“and” vs “or”) is really about your point of view. Note though that quantum mechanics is itself just a simplified way of modeling what happens due to field theory. Under field theory, fields are central, and particles are just phenomena that happen under fields. It is of course possible that in a more fundamental theory, particles are central and their interaction just results in field-like behavior.
