Sabine Hossenfelder: Phenomenological Quantum Gravity

The search for a satisfying theory that unifies general relativity with quantum field theory is surely one of the major tasks for physicists in the 21st century. During the last decade, the phenomenology of quantum gravity and string theory has been examined from various points of view, opening new perspectives and testable predictions. I will give a short introduction into these effective models which allow to extend the standard model and include the expected effects of the underlying fundamental theory. I will talk about models with extra dimensions, models with a minimal length scale and those with a deformation of Lorentz invariance. The focus is on observable consequences, such as black hole and graviton production and modifications of standard-model cross-sections.

Since I have an interest in the work being done on minimum length, I have listed some papers which I found. (Saves you the time to dig them up)

Is anyone aware of any refinement being done on the calculations?

Finding out if there is a minimum length is probably one of the oldest question.
Since CERN will be probing new length scales, I am surprised that I'm not finding more papers that proposes that the results would look like ? and would indicate the minimum length scale. (ie. like the paper by Gautam Bhattacharyya, Kumar Rao, K. Sridhar)
Maybe the papers are there but only by insinuations. They don't say, "the minimum length scale".
Finding or not finding the minimum length scale will have an effect. The papers should be out there before CERN "opens the box".

I am intrigued by the work being done in the field of phenomenological quantum gravity by Sabine Hossenfelder and others. The search for a theory that unifies general relativity and quantum field theory is a challenging and important task, and the development of effective models that can extend the standard model and incorporate the effects of a fundamental theory is a promising approach.

I appreciate the effort made by Hossenfelder to study the effects of a minimum length scale in various models, such as those with extra dimensions and a deformation of Lorentz invariance. These models have exciting and testable predictions, such as black hole and graviton production, as well as modifications to standard model cross-sections.

I have looked into some of the papers listed and am interested in any potential refinements being made on the calculations. It is clear that this research has the potential to greatly advance our understanding of quantum gravity and potentially lead to new insights and discoveries. I look forward to following the progress in this field and seeing how it contributes to the larger goal of unifying our understanding of the fundamental forces in the universe.
