Abstract: It is shown by both analytical methods and numerical simulations thatextremely long living spherically symmetric oscillons appear in virtually anyreal scalar field theory coupled to a massless dilaton DS theories. In factsuch -dilatonic- oscillons are already present in the simplest non-trivial DStheory - a free massive scalar field coupled to the dilaton. It is shown thatin analogy to the previously considered cases with a single nonlinear scalarfield, in DS theories there are also time periodic quasibreathers QBassociated to small amplitude oscillons. Exploiting the QB picture theradiation law of the small amplitude dilatonic oscillons is determinedanalytically.
