Rosati

DSR in Cosmological SpTm Can CMB be directly probing QG? do we need Inflation as “intermediary”?

SLIDE 7

“General Trends” my Bias View

Obs/Exp Constraints QG Scenarios/Models (hopefully testable!) Experiments

Lorentz Breaking SME (EFT approach): QED and Baryon Sector heavily Constrained.

  • Margins of improvements in

Neutrino sector & Gravity

  • Sector. Gravity seem to need

sub-Planck LIV…

  • Look better at Non-EFT

scenarios?

  • Other ideas to test about

Mesoscopic spacetime physics? My bet, Non-Locality

  • can we test which kind of

discreteness is associated to Planck scale physics? Moving from blind searches to testing “plausible” QG scenarios

  • Have we looked in the right

place? With LIV (as preferred frame) there is a preferred notion

  • f Planck length/energy. What is

the QG regime in LI scenarios?

  • Regular black holes! Event

horizons are finally demode’! Dawn of quantum Bounces phenomenology in Cosmology as well.

Discussion

Have your say!

Need better UHE Neutrino and CR observations!

  • Need better CMB

polarisation measurement.

  • But is cosmology really

doing QG phenomenology

  • Need better knowledge of

UV regime of Gravity (not necessarily at Mpl

  • Are macroscopic quantum
  • bjects interesting for QG

phenomenology?
