• [hal-04558900] The CCube reconstruction algorithm for the SoLid experiment
  The SoLid experiment is a very-short-baseline experiment aimed at searching for nuclear reactor-produced active to sterile antineutrino oscillations. The detection principle is based on the pairing of two types of solid scintillators: polyvinyl toluene and $^6$LiF:ZnS(Ag), which is a new technology used in this field of Physics. In addition to good neutron-gamma discrimination, this setup […]
• [hal-04558657] A first extraction of the weak magnetism form factor and Fierz interference term from the $^{114}$In $\rightarrow$$^{114}$Sn Gamow-Teller transition
  Spectrum shape measurements in nuclear $\beta$ decay can be used to test physics beyond the Standard Model with results being complementary to high-energy collider experiments. In particular, Beyond Standard Model sensitivity of the weak interaction is expressed through the so-called Fierz interference term. Additionally, the $\beta$ spectrum shape is a useful tool to probe Standard […]
• [hal-04557966] Multiplicity of prompt fission neutron in the $^{239}$Pu(n,f) reaction and its energy dependence
  Accurate multiplicities of prompt fission neutrons emitted in neutron-induced fission on a large energy range are essential for fundamental and applied nuclear physics. Measuring them to high precision for radioactive fissioning nuclides is, however, an experimental challenge. In this work, we extract the average prompt-neutron multiplicity emitted in the 239 Pu (n, f) reaction as […]
• [hal-04557838] Direct Experimental Constraints on the Spatial Extent of a Neutrino Wavepacket
  Despite their high relative abundance in our Universe, neutrinos are the least understood fundamental particles of nature. They also provide a unique system to study quantum coherence in fundamental systems due to their extremely weak interaction probabilities. The quantum properties of neutrinos emitted in experimentally relevant sources are virtually unknown and theoretical predictions for the […]
• [hal-04557495] Search for Neutrino Emission from GRB 221009A using the KM3NeT ARCA and ORCA detectors
  Gamma-ray bursts are promising candidate sources of high-energy astrophysical neutrinos. The recent GRB 221009A event, identified as the brightest gamma-ray burst ever detected, provides a unique opportunity to investigate hadronic emissions involving neutrinos. The KM3NeT undersea neutrino detectors participated in the worldwide follow-up effort triggered by the event, searching for neutrino events. In this letter, […]
