Figure 4: Cross section for scattering of two scalar particles by graviton exchange with and without running Planck mass, in units of the low-energy Planck mass √ --- 1∕ G0. The dot-dashed (purple) line depicts the case without asymptotic safety; the continuous (blue) and dashed (grey) line take into account the running of the Planck mass, for two different values of the fixed point, ∘ --- 1∕ &tidle;G∗ = 0.024 and 0.1 respectively.
