SM-GR reconciliation and dark sector

Poincare breaking scale causes explicit gauge invariance breaking at the loop level in the standard model (SM) – a renormalizable QFT in flat spacetime. In this talk, we show that gauge invariance can be restored by extending the general covariance by a covariance relation for curvature such that this extended covariance carries effective QFTs into curved spacetime to lead up to QFT-GR reconciliation, with renormalized QFTs and emergent GR. This mechanism predicts the existence of new physics beyond the SM (BSM), and does not necessitate the BSM sector to have any non-gravitational coupling with the SM. The BSM sector can have a dark subsector comprising the dark matter, dark energy, and other possible SM-singlet fields.
