A simple solution to the fine tuning problem of the cosmological constant

Abstract

We show that the fine tuning problem of the cosmological constant can be solved in a conformal model, with explicit conformal symmetry breaking. We argue that the model has two different terms which essentially contribute to the cosmological constant. A local conformal transformation leads to a cancellation of these two terms among one another. Hence these produce no physical consequence. The model generates a small cosmological constant without requiring any fine tuning.
