Description

In the standard QFT approach to the calculation of the cosmological constant contributions from the gravitational sector are usually neglected. Using a simple two-dimensional scenario, but in connection with higher dimensions, we discuss the possibility that quantum gravity can play an important role in the calculation of Λ, providing large quantum corrections and renormalizations. We reproduce the QFT result as a sub-case, while allowing a very large set of values.
