The coming decade is poised to witness an abundance of measurements with the potential of substantial improvements of our understanding of neutrino physics. Many of these measurements can be harnessed for unprecedented studies of both Lorentz and CPT invariance, two closely intertwined cornerstones of established physics. These symmetries may nevertheless be violated in many theoretical...
The hadron cascade model is an essential part of Monte Carlo neutrino event generators that governs the final-state interactions of knocked-out nucleons and produced pions. Working in the context of NuWro, we show that such a model, enriched with physically motivated modifications of nucleon-nucleon cross sections and incorporation of nuclear correlation effects, can reproduce experimental...
In this talk I will summarize our recent Snowmass LOI on “Microscopic approaches to neutrino-nucleus interactions”. The advent of high precision measurements of neutrinos and their oscillations calls for precise theoretical calculations of neutrino scattering cross sections on target nuclei utilized in the detectors. Over the past decade, ab initio methods based on realistic nuclear...
The energy spectrum of neutrinos at DUNE is peaked in the few GeV region, where quantifying nuclear model uncertainties arising from nonperturbative quantum chromodyanmics (QCD) effects is particularly challenging. A coherent set of theoretical frameworks is required to describe neutrino interactions with nuclei with the level of accuracy needed for the success of DUNE and other precision...
Chiral effective field theory (EFT) provides nuclear interactions as well as electroweak currents constructed in a rigorous framework that allows systematic improvement and uncertainty quantification. Multipole decomposition of the chiral EFT current operators is an essential first step in calculating quasielastic neutrino cross sections using several state-of-the-art methods in nuclear...
Knowing accurately the neutrino-nucleus cross section is of prime importance for extracting the neutrino properties from experimental data. In this endeavour, one crucial ingredient is the axial form factor of the nucleon.In this talk, we will discuss the implications of the recent lattice QCD results for neutrino-nucleus cross sections.
The observation of coherent elastic neutrino-nucleus scattering (CEνNS) performed, in 2017 with cesium iodide and in 2020 with liquid argon by the COHERENT experiment unlocked an innovative and powerful tool to study many and diverse physical phenomena.
CEνNS is a neutral current process induced by the exchange of a Z boson. It thus represents also a sensitive probe for non-standard...
