A BornInfeld scalar and a dynamical violation of the scale invariance from the modified measure action
Abstract
Starting with a simple twoscalar field system coupled to a modified measure that is independent of the metric, we, first, find a BornInfeld dynamics sector of the theory for a scalar field and second, show that the initial scale invariance of the action is dynamically broken and leads to a scale charge nonconservation, although there is still a conserved dilatation current.
