Measuring the leptonic CP phase $\delta_{CP}$ and resolving the
$\theta_{23}$ octant are primary objectives of DUNE and T2HK.
We show that two distinct effects can compromise the reliability of
these measurements. First, the poorly constrained $\nu_e$ and
$\bar{\nu}_e$ cross sections allow energy-dependent distortions that
partially mimic the $\delta_{CP}$-dependent spectral...
Several experiments in the next few years will determine the value of the CP-violating phase $\delta$. In accelerator neutrino experiments, such a measurement is usually performed by comparing the oscillation probabilities in the neutrino and antineutrino sectors to break degeneracies with other oscillation parameters. Such an approach has some downsides, however: for instance, the cross...
We compute electromagnetic radiative corrections in the inverse beta decay at reactor antineutrino energies within the heavy baryon chiral perturbation theory, provide the most accurate cross-section predictions for this process, present a complete error budget, and investigate impact on the energy reconstruction at JUNO. For the first time, we consistently include quantum electrodynamics,...
After successful operation at LNGS and a major upgrade at CERN, the 760-ton ICARUS T600 detector has been running at Fermilab since 2020, collecting neutrino interactions from the BNB and NuMI beams.
In late 2025, ICARUS reached five years of continuous data taking, demonstrating the maturity of large-scale LAr-TPC technology and its relevance for future experiments such as DUNE.
First...
