The abstract, sentence by sentence

arXiv listing abstract v1. Results and the main claim are underlined; show every role.

Large extra dimensions are one of the constructions addressing the hierarchy problem of the Standard Model. Their main theoretical and phenomenological challenge is that already predicting LHC effects requires an ultraviolet completion of TeV-scale gravity. In these lecture notes we first give a basic introduction into TeV-scale gravity models and their collider effects and then discuss possible ultraviolet completions, like string theory and fixed-point gravity.

The paper

Original abstract

Large extra dimensions are one of the constructions addressing the hierarchy problem of the Standard Model. Their main theoretical and phenomenological challenge is that already predicting LHC effects requires an ultraviolet completion of TeV-scale gravity. In these lecture notes we first give a basic introduction into TeV-scale gravity models and their collider effects and then discuss possible ultraviolet completions, like string theory and fixed-point gravity.

Signed neural control variates from normalizing flows, combined with neural importance sampling, reduce weight ranges and negative weights for LO and NLO phase-space integration and event generation.

L-GATr-slim with a pseudoscalar channel achieves a spin-analyzing power of 0.721 for hadronic top decays and learns a pseudoscalar output that acts as an optimal CP-odd observable, outperforming manual constructions.
Black holes and asymptotically safe gravity

Running the gravitational coupling with distance in d-dimensional Schwarzschild black holes yields a minimum black hole mass, a cold remnant with vanishing temperature, and a suppressed but semi-classical collider cro...
Ghost wave-function renormalization in Asymptotically Safe Quantum Gravity
hep-th 2010-01 conditional novelty 5.0 of 10

Adding ghost wave-function renormalization to the Einstein-Hilbert truncation leaves the non-trivial ultraviolet fixed point intact and yields a ghost anomalous dimension of about -1.8 in four dimensions.
Renormalisation group and the Planck scale

A review argues that functional renormalisation group calculations give growing evidence for a non-trivial ultraviolet fixed point in four-dimensional quantum gravity, the asymptotic safety scenario.
