The Kaluza-Klein scenario reveals that brane fermions induce torsion, creating a dominant axial contact interaction. This interaction significantly enhances the quantum gravity scale bound to 28 TeV.

Area of Science:

  • Theoretical Physics
  • High Energy Physics
  • String Theory

Background:

  • The Kaluza-Klein (KK) scenario posits gravity in higher dimensions.
  • Investigating scenarios without assuming symmetric connections is crucial for understanding fundamental forces.
  • The role of brane-localized matter in modified gravity theories needs exploration.

Purpose of the Study:

  • To analyze the Kaluza-Klein scenario where only gravity exists in the bulk.
  • To investigate the effects of brane fermions on spacetime torsion.
  • To determine the dominant interactions and their impact on quantum gravity scales.

Main Methods:

  • Considering the Kaluza-Klein scenario without symmetric connection assumptions.
  • Analyzing the induction of torsion by brane fermions.

Related Experiment Videos

  • Calculating the resulting axial contact interaction and its enhancement due to spin density.
  • Performing a global fit to Z-pole observables.
  • Utilizing SN1987A data for neutrino-related constraints.

    • Main Results:

    • Brane fermions induce torsion in the absence of symmetric connections.
    • A universal axial contact interaction arises, dominating KK graviton-induced interactions.
    • This enhancement stems from a large spin density on the brane.
    • A 3-sigma bound of 28 TeV on the quantum gravity scale is found for n=2 using Z-pole data.
    • SN1987A data improve the bound to sqrt[n] M(S) >= 210 TeV with Dirac or sterile neutrinos.

    Conclusions:

    • The induced axial contact interaction provides a significant probe of quantum gravity scales.
    • The Kaluza-Klein scenario with brane fermions offers a mechanism for enhanced gravitational effects.
    • Experimental and astrophysical data place stringent limits on the fundamental scale of quantum gravity.
