Searches for heavy neutral lepton decays at spallation neutron sources
Valentina De Romeri, A. Galindo-Uribarri, Ana Martín-Galán +2
Spallation neutron sources provide intense neutrino fluxes from pion and muon decay at rest, with energies in the few tens of MeV range. Experiments such as COHERENT exploit these…
Invisible decay of solar neutrinos at dark matter experiments
Martina Beccaria, Veronica Beligotti, Valentina De Romeri +4
The combination of the long baseline and characteristic energies of solar neutrinos offers an ideal framework to probe invisible neutrino decay. In this work we present the first c…
The swallowed spike: the formation of light primordial black hole structures around heavy seeds
Agnese Tolino, Francesca Scarcella, Bradley J. Kavanagh +2
Spikes are steep enhancements in the dark matter (DM) distribution around a heavy compact object. If the compact object is primordial, and the bulk of the DM is also composed of (l…
Refined extraction of electroweak and nuclear parameters from germanium CENS data
Valentina De Romeri, Laura Duque, Dimitrios K. Papoulias +2
We present a combined analysis of recent CENS data on germanium from two complementary experiments: COHERENT, which uses neutrinos from pion decay at rest, and CONUS+, which det…

Current ton-scale, xenon-based dark matter (DM) direct detection experiments have now reached the sensitivity required to observe solar neutrinos, marking the onset of the so-calle…
Spatial and Temporal Evaluations of the Liquid Argon Purity in ProtoDUNE-SP
DUNE Collaboration, S. Abbaslu, A. Abed Abud +1320
Liquid argon time projection chambers (LArTPCs) rely on highly pure argon to ensure that ionization electrons produced by charged particles reach readout arrays. ProtoDUNE Single-P…

Recently, two dark matter direct detection experiments have announced the first indications of nuclear recoils from solar B neutrinos via coherent elastic neutrino-nucleus scat…
Primordial black hole probes of heavy neutral leptons
Valentina De Romeri, Yuber F. Perez-Gonzalez, Agnese Tolino
Primordial black holes (PBH), while still constituting a viable dark matter component, are expected to evaporate through Hawking radiation. Assuming the semi-classical approximatio…
