2 Day 1 Stecker LIV via HE Astro? Eichhorn ERG scenarios Benincasa CAUSET Phenomenology Carmona Thresholds with Modified Kinematics and Composition Laws Esposito QG corrections in 3-body problem Pickowski Quantum Optical System searches Marin QG Phen. with Macroscopic Mechanical Oscillators Quantum discreteness vs spacetime Discreteness Can macroscopic bodies COM test quantum spacetime? Lorentz Invariance+Discreteness=Non-Locality?

3 Day 2 LQG-LQC inspired Scenarios Ferte on Chiral Gravity via CMB Creminelli Inflationary scenarios and B-Modes Alexander Parity violating Cosmology Grain Loop Quantum Cosmology Mercedes Martin-Benito Relic signatures of Quantum Production of GW Keating BICEP2 and B-Modes Bielewicz PLANCK 2013 Results Fabbian POLARBEAR B-Modes Have we seen QG via B-Modes detection? Do current observations really support Inflation. Are we trapped in the inflationary paradigm?

4 Day 3 Granot on LIV from FERMI GRBs Vidotto Planck stars Phenomenology Hossenfelder Spacetime defects Rovelli Planck stars Mazumdar Non-local action of higher derivative Gravity LQG-LQC inspired Scenarios FERMI and similar Cianfrani Quantum reduced LQG Trzesniewski Running of spectral dimensions in k-minkowski Dominated by Planck stars. Many questions. Chirco Thermally correlated states of Loop Quantum Gravity

5 Day 4 LQG-LQC inspired Scenarios Mielczarek LQC effects on CMB Miller QG (gravitons) effects on Neutrino Oscillations Kowalski-Glikman Relative Locality in 2+1 Dim. Gubitosi Spectral dimension reduction and cosmology on CMB Low energy neutrino detectors Castignani FERMI GRBs Time Delays Magueijo Spectral dimension reduction and cosmology Rosati DSR in Cosmological SpTm Loret Finsler interpretation of k-poincaré Is there relative locality without particles? Can CMB be directly probing QG? do we need Inflation as intermediary? My addition: Is DSR fundamental of mesoscopic?

6 Day 5 Obs/Exp QG Scenarios/Models LQG-LQC inspired Scenarios Mattingly LIV BH Thermo Kelley IceCube HE Neutrinos Oriti Emergent spacetime as a condensate in QG Quantum vs Emergent Matter from QG QG LI = Classical LI?

7 General Trends my Bias View 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 of 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. 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 objects interesting for QG phenomenology? Have your say
