The KM3NeT/ORCA detector (Oscillation Research with Cosmics in the Abyss) is an underwater array of Digital Optical Modules. These are spheres that host 31 photomultiplier tubes each, and they are tied together in vertical structures (the Detection Units-DUs) anchored on the seabed. This configuration allows the detection of neutrino events using the Cherenkov radiation emitted by secondary...
The Accelerator Neutrino Neutron Interaction Experiment (ANNIE) is a 26-ton Gd-doped water Cherenkov detector installed in the Booster Neutrino Beam (BNB) at Fermilab. The main physics goal of the experiment is to measure the final state neutron multiplicity of neutrino-nucleus interactions to improve the systematic uncertainties in oscillation experiments. Complementing this goal, ANNIE tests...
In this contribution the most recent results of an all-flavour search for diffuse astrophysical neutrino fluxes, using the full dataset obtained with the first KM3NeT/ARCA configurations, will be presented. KM3NeT/ARCA is part of the KM3NeT research infrastructure and focuses on the detection of high energy neutrinos (>TeV) from astrophysical sources. The KM3NeT/ARCA detection units are...
The event rate from dark matter interactions is expected to exhibit an annual modulation due to the galactic halo distribution of dark matter. However, this signature has only been observed in the DAMA/LIBRA experiment, which used NaI(Tl) scintillators. While their results could suggest dark matter scattering, no other experiment has successfully replicated these findings. To address this...
Measurements of jet substructure are key to probing the energy frontier at colliders, and many of them use track-based observables which take advantage of the angular precision of tracking detectors. Theoretical calculations of track-based observables require “track functions”, which characterize the transverse momentum fraction $r_q$ carried by charged hadrons from a fragmenting quark or...
Measurements of the differential cross section for isolated-photon production in proton-proton collisions at a centre of mass energy of 13 TeV are presented. The analysis uses data collected by the ATLAS detector at the LHC, corresponding to an integrated luminosity of 139 fb-1. Cross sections are measured as a function of the photon transverse energy in various regions of photon...
Muons, created in interactions of cosmic rays with the Earth's atmosphere, are the main component of cosmic ray air showers which reach underwater or in-ice neutrino telescopes such as KM3NeT and IceCube. Measurements of such muons provide crucial information about the properties of cosmic rays, and their interactions with the atmosphere. The KM3NeT research infrastructure includes two...
