Does supersymmetry rule out asymptotic safety?

In summary, the article discusses the asymptotic safety of the Standard Model with gravity. It shows that the Higgs mass can be predicted to be between 126 and 174 GeV, with only a few GeV uncertainty. This is independent of the details of the short distance running. The case where Aλ>0 is favored by computations existing in the literature.

If we find supersymmetry at the LHC, would this prove asymptotic safety in QG wrong?

What I understand from the abstract is that they proved a large number of supersymmetric theories can't be asymptotically safe. It still leaves non-supersymmetric theories and supersymmetric theories that don't satisfy their assumptions.

From my perspective this paper is nearly irrelevant.

Usually asymptotic safety is applied to theories for gravity plus matter. This paper deals with supersymmetry, but without matter.

I guess the idea is to continue with gravity, SUGRA, ...

this paper assumes no supersymmetry

Asymptotic safety of gravity and the Higgs boson mass

There are indications that gravity is asymptotically safe. The Standard Model (SM) plus gravity could be valid up to arbitrarily high energies. Supposing that this is indeed the case and assuming that there are no intermediate energy scales between the Fermi and Planck scales we address the question of whether the mass of the Higgs boson mH can be predicted. For a positive gravity induced anomalous dimension Aλ>0 the running of the quartic scalar self interaction λ at scales beyond the Planck mass is determined by a fixed point at zero. This results in mH=mmin=126 GeV, with only a few GeV uncertainty. This prediction is independent of the details of the short distance running and holds for a wide class of extensions of the SM as well. For Aλ<0 one finds mH in the interval mmin<mH<mmax≃174 GeV, now sensitive to Aλ and other properties of the short distance running. The case Aλ>0 is favored by explicit computations existing in the literature.

What is supersymmetry and asymptotic safety?

Supersymmetry is a theoretical concept in physics that proposes a symmetry between particles with different spin values. Asymptotic safety is a hypothesis that suggests that the laws of physics remain consistent even at extremely high energies.

How does supersymmetry relate to asymptotic safety?

Supersymmetry does not necessarily rule out asymptotic safety, but it is a topic of debate among physicists. Some theories propose that supersymmetry may actually support the idea of asymptotic safety, while others suggest that it may be incompatible with it.

What evidence supports or refutes the idea of supersymmetry ruling out asymptotic safety?

Currently, there is no concrete evidence either supporting or refuting the idea of supersymmetry ruling out asymptotic safety. This is an area of ongoing research and debate in the field of theoretical physics.

Why is the question of supersymmetry ruling out asymptotic safety important in the field of physics?

The question is important because it has implications for our understanding of the fundamental laws of physics and their behavior at extreme energies. Finding a resolution to this question could lead to a deeper understanding of the universe and potentially new discoveries in physics.

Are there any experiments or observations that could help answer this question?

Currently, there are no experiments or observations that can definitively answer the question of whether supersymmetry rules out asymptotic safety. However, ongoing research and advancements in technology may eventually provide new insights and evidence in the future.
