Bee's new paper on QG phenomenology

[marcus]

It's a good paper. She delivered it in June at the Irvine SUSY 06 conference but we didnt get to see it until now.

It has a confusing passage on page 2, at the bottom, right before the Feynman diagram on page 3.

In contrast to the asymptotic momenta p, the wave-vector k of the particle in the interaction region will behave non-trivially because strong gravitational effects disturb the propagation of the wave. In particular, it will not transform as a standard (flat space) Lorentz-vector, and obey the MDR.

I suppose the intended meaning is " In particular, it will not transform as a standard (flat space) Lorentz-vector, but* WILL INSTEAD obey the MDR."

As an English speaker the literal meaning I get is opposite to this:
" In particular, it will not transform as a standard (flat space) Lorentz-vector, and (also will not) obey the MDR."

In any case there is some linguistic ambiguity.

Here is the paper:

Phenomenological Quantum Gravity
S. Hossenfelder
To appear in Proceedings of SUSY06, the 14th International Conference on Supersymmetry and the Unification of Fundamental Interactions, UC Irvine, California, 12-17 June 2006

"Planck scale physics represents a future challenge, located between particle physics and general relativity. The Planck scale marks a threshold beyond which the old description of spacetime breaks down and conceptually new phenomena must appear. In the last years, increased efforts have been made to examine the phenomenology of quantum gravity, even if the full theory is still unknown."

[EDIT] selfAdjoint suggested saying "but" and I adopted that and edited it in. See his next post.

In particular, it will not transform as a standard (flat space) Lorentz-vector, and obey the MDR.

Right, I think the sentence will read as she intended if we replace the "and" with a "but".

Thank you for sharing this paper by Bee on quantum gravity phenomenology. It is exciting to see new research being presented at the SUSY 06 conference in Irvine. However, I noticed a potential ambiguity in a passage on page 2 regarding the behavior of the wave-vector k in the interaction region. The sentence states that "it will not transform as a standard (flat space) Lorentz-vector, and obey the MDR." I believe the intended meaning is that it will instead obey the MDR, but as an English speaker, the literal interpretation could also be that it will not obey the MDR. It may be helpful to clarify this statement for better understanding. Overall, the paper offers valuable insights into the challenges and potential developments in quantum gravity phenomenology, which is crucial for bridging the gap between particle physics and general relativity.
