Holography and Localization of Information in Quantum Gravity / Bahiru, Eyoab (SISSA, Trieste ; INFN, Trieste ; ICTP, Trieste) ; Belin, Alexandre (Milan Bicocca U. ; Ecole Polytechnique, Lausanne) ; Papadodimas, Kyriakos (King's Coll. London ; CERN) ; Sarosi, Gabor (King's Coll. London ; CERN) ; Vardian, Niloofar (SISSA, Trieste ; INFN, Trieste)
Within the AdS/CFT correspondence, we identify a class of CFT operators which represent diff-invariant and approximately local observables in the gravitational dual. [...]

UV and IR Effects in Axion Quality Control / Burgess, C.P. (McMaster U. ; Perimeter Inst. Theor. Phys.) ; Choi, Gongjun (CERN) ; Quevedo, F. (Cambridge U., DAMTP)
Motivated by recent discussions and the absence of exact global symmetries in UV completions of gravity we re-examine the axion quality problem (and naturalness issues more generally) using antisymmetric Kalb-Ramond (KR) fields rather than their pseudoscalar duals, as suggested by string and higher dimensional theories. [...]

Anomaly Cancellation in Effective Field Theories From the Covariant Derivative Expansion / Cohen, Timothy (CERN ; EPFL, Lausanne, LPTP ; Oregon U.) ; Lu, Xiaochuan (Oregon U. ; UC, San Diego) ; Zhang, Zhengkang (UC, Santa Barbara)
We extend our recently-proposed formalism for calculating anomalies of global and gauge symmetries using the Covariant Derivative Expansion to include a general class of operators that can appear in relativistic Effective Field Theories (EFTs). [...]

We study the impact of neutrino magnetic moments on astrophysical neutrinos, in particular supernova neutrinos and ultra-high energy neutrinos from extragalactic sources. [...]

Gravity, Horizons and Open EFTs / Burgess, C.P. (McMaster U. ; Perimeter Inst. Theor. Phys. ; CERN ; Dublin Inst.) ; Kaplanek, Greg (Imperial Coll., London)
Wilsonian effective theories exploit hierarchies of scale to simplify the description of low-energy behaviour and play as central a role for gravity as for the rest of physics. [...]
