Asymptotic freedom of Yang-Mills theory with gravity

Understand

We study the behaviour of Yang-Mills theory under the inclusion of gravity.

• In the weak- gravity limit, the running gauge coupling receives no contribution from the gravitational sector, if all symmetries are preserved.
• This holds true with and without cosmological constant.
• We also show that asymptotic freedom persists in general field-theory-based gravity scenarios including gravitational shielding as well as asymptotically safe gravity.
