Abstract
One possible solution of the cosmological constant problem involves a so-called -field, which self-adjusts so as to give a vanishing gravitating vacuum energy density (cosmological constant) in equilibrium. We show that this -field can manifest itself in other ways. Specifically, we establish a propagating mode (-wave) in the nontrivial vacuum and find a particular soliton-type solution in flat spacetime, which we call a -ball by analogy with the well-known -ball solution. Both -waves and -balls are expected to play a role for the equilibration of the -field in the very early universe.
