An infrared on-shell action in asymptotically flat spacetimes / Raclariu, Ana-Maria (speaker) (King's College London)
One of the main entries in the AdS/CFT dictionary is a relation between the bulk on-shell partition function with specified boundary conditions and the generating function of correlation functions of primary operators in the boundary CFT. In this talk, I will show how to construct a similar relation for gravity in 4d asymptotically flat spacetimes [...]

The Super Fine-Grained Detector (SuperFGD) for the T2K neutrino oscillation experiment / Sgalaberna, Davide (speaker) (ETH Zurich (CH))
T2K is a long-baseline neutrino oscillation experiment in Japan that searches for leptonic CP violation. The magnetised near detector (ND280) has the role of constraining the dominant systematic uncertainties, related to the neutrino flux and interaction cross section, in the measurement of the neutrino oscillation probability.

Galaxies as Probes of the Particle Physics Nature of Dark Matter / Lisanti, Mariangela (speaker) (Princeton University)
The hypothesis of Cold Dark Matter (CDM) has been spectacularly confirmed on the largest scales of the Universe and must now be stress-tested on sub-galactic scales.   Many well-motivated and generic alternatives to CDM can leave spectacular signatures on precisely these scales, affecting the evolution of galaxies as well as their population statistics.

Deriving the long-string CFT in AdS3 / Knighton, Bob (speaker) (Cambridge)
The identification of the CFT dual of string theory in AdS3 is a long-standing open problem, and little is known outside of very special cases. Recently, a (perturbative) CFT dual for bosonic string theory in AdS3 was proposed, based on a deformed symmetric product CFT. [...]

CMOS Monolithic Active Pixel Sensors: challenges and perspectives / Snoeys, Walter (speaker) (CERN)
CMOS cameras revolutionized the visible imaging world, and now move into other fields.  CMOS Monolithic Active Pixel Sensors (CMOS MAPS) have been successfully used in the STAR experiment and are now taking data in the 10 m2 Inner Tracker System (ITS2) of the ALICE experiment at CERN. CMOS MAPS in high energy physics (HEP) continue to be the object of intense research and development, for instance in EP R&D WP1.2 and DRDs, and for future ALICE and LHCb upgrades­, and detectors at FCC.  CMOS MAPS for HEP face very different requirements, but their development greatly benefits from the progress of CMOS imagers for visible light, the integration offered by stitching and wafer stacking, as well as trends in mainstream CMOS. 3D wafer stacking and stitching are now well established for CMOS sensors for visible light, and stacking is also now intensely pursued in mainstream CMOS.
