Physics of the D=5 Chern-Simons Term

Physics of the D=5 Chern-Simons Term. C.T. Hill, Fermilab. I. QED in D=5. Photons propagate in bulk; Naturalness, m e << 1/R, requires chiral delocalization; Wilson-line mass term. (b) Chiral delocalization requires a Chern-Simons term.

Weak Gravity Unification With The Quantum Vacuum

A low energy gauge theory coupled to a scalar tensor has a precise interrelationship to Monster group symmetry (hidden) across a slight energetic vacuum change from the near flat Minkowski type gentle curving space time of the regular uud-ddu (proton neutron) flavor fields to more extremal space time curvature near a neutron (or black hole) star in the ddu-ddu (neutron ) flavor fields. The nature of the scalar tensor only slightly violates EP in the weak gravity realm. In addition it is suggested that a highly symmetric version of Scalar Tensor Theory is the correct theory operating in the realm of Newton-Einstein Gravity. ( Power Point Presentation 41 Slides)

Weak Gravity Unification with the Quantum Vacuum

A low energy gauge theory coupled to a scalar-tensor has a precise interrelationship to Monster group symmetry across a slight energetic vacuum change from the near flat Minkowski type gentle curving space-time of the regular uud-ddu (proton-neutron) flavor fields to more extremal space-time curvature near a neutron (or black hole) star in the ddu-ddu (neutron ) flavor fields. The nature of the scalar-tensor only slightly violates EP in the weak gravity realm.
