Oral presentation in parallel session
This talk will present the science case for a future generation-3 liquid xenon time projection chamber for astroparticle physics. Such an experiment is envisioned to follow the current generation of experiments such as LZ and XENONnT, delivering diverse science at moderate cost. With a sensitivity sufficient to probe WIMP dark matter down to the signal from atmospheric neutrinos, numerous...

THEIA is a proposed large-scale neutrino experiment based on advanced liquid scintillator and readout by high-quantum efficiency and fast photosensors. In order to combine the advantages of water Cherenkov detectors (i.e. large mass, direction reconstruction and low cost) with the ones of liquid scintillator (high light yield, low threshold) THEIA will deploy a Water-based Liquid Scintillator,...

We studied the effects of the positive ion current in a noble gas time projection chamber, in the context of massive argon experiments for neutrino physics and dark matter searches. The space charge can modify the drift lines, the amplitude of the electric field, and ultimately the velocity of the electrons, thus, a displacement in the reconstructed position of the ionization signal can be...

Super-Kamiokande (SK), the world's largest underground water Cherenkov detector, observes about 2 muons a second passing through it at a depth of 1 km. A fraction of these muons shower, and sometimes create radioactive isotopes (spallation). Those isotopes live anywhere from microseconds to several seconds, forming a dominant background to neutrino searches above 6 MeV and below 20 MeV....

Oral presentation in parallel session
Neutral-current (NC) elastic interactions of atmospheric neutrinos on oxygen is a major background in searches for supernova relic neutrinos (SRNs) at Super-Kamiokande.
In the current analysis, a large uncertainty is assigned for the NC elastic cross section, which limits the sensitivity especially in a low energy region of <18 MeV.
To improve the situation, the NC elastic interaction...
