Original abstract

The chameleonic behaviour of the String theory dilaton is suggested. Some of the possible consequences of the chameleonic string dilaton are analyzed in detail. In particular, (1) we suggest a new stringy solution to the cosmological constant problem and (2) we point out the non-equivalence of different conformal frames at the quantum level. In order to obtain these results, we start taking into account the (strong coupling) string loop expansion in the string frame (S-frame), therefore the so-called form factors are present in the effective action. The correct Dark Energy scale is recovered in the Einstein frame (E-frame) without unnatural fine-tunings and this result is robust against all quantum corrections, granted that we assume a proper structure of the S-frame form factors in the strong coupling regime. At this stage, the possibility still exists that a certain amount of fine-tuning may be required to satisfy some phenomenological constraints. Moreover in the E-frame, in our proposal, all the interactions are switched off on cosmological length scales (i.e. the theory is IR-free), while higher derivative gravitational terms might be present locally (on short distances) and it remains to be seen whether these facts clash with phenomenology.

  • In other words, we replace the anomaly-induced coupling of [ref] between $σ$ and the matter density (where the matter fields were represented by a scalar field $Φ_*$) with a coupling between $σ$ and a matter density represented by a spinor field (like in the Olive-Pospelov approach).

  • In the case we mentioned last, the shell is the thinnest that can be analyzed by the computer and the results are basically indistinguishable from a Standard Solar Model (SSM). * In order to explore further the connection between chameleon fields and solar physics, we consider a ”Modified Fujii's Model” (MFM) recently analyzed in [ref] and we show that, in this model, a conceivable interpretation of the solar oscillations is given by quantum vacuum fluctuations.
