- Title
A Strategy for a Vanishing Cosmological Constant in the Presence of Scale Invariance Breaking.

- Abstract
Recent work has shown that complex quantum field theory emerges as a statistical mechanical approximation to an underlying noncommutative operator dynamics based on a total trace action. In this dynamics, scale invariance of the trace action becomes the statement 0 = Re Tr Tμμ, with Tμυ the operator stress energy tensor, and with Tr the trace over the underlying Hilbert space. We show that this condition implies the vanishing of the cosmological constant and vacuum energy in the emergent quantum field theory. However, since the scale invariance condition does not require the operator Tμμ to vanish, the spontaneous breakdown of scale invariance is still permitted.
