# Exploring the self-tuning of the cosmological constant from Planck mass variation

@article{Blanco2020ExploringTS, title={Exploring the self-tuning of the cosmological constant from Planck mass variation}, author={Daniel Sobral Blanco and Lucas Lombriser}, journal={Classical and Quantum Gravity}, year={2020}, volume={38} }

Recently, the variation of the Planck mass in the general relativistic Einstein–Hilbert action was proposed as a self-tuning mechanism of the cosmological constant, preventing standard model vacuum energy from freely gravitating and enabling an estimation of the magnitude of its observed value. We explore here new aspects of this proposal. We first develop an equivalent Einstein-frame formalism to the current Jordan-frame formulation of the mechanism and use this to highlight similarities and…
