The MEG experiment at Paul Scherrer Institut (Zurich โ Switzerland) established in 2016 the best current upper limit of $4.2 \times 10^{-13}$ on the branching ratio of the $\mu->e \gamma$ decay. The search for this decay represents an extremely powerful tool to look for possible extensions of the Standard Model since its existence would unambiguously represent a sign of new physics.

The Mu3e experiment will search for the charged lepton flavour violating decay $\mu \rightarrow e^+ e^- e^+$ and is based at the Paul Scherrer Institute (PSI). It aims to achieve a sensitivity of one in $\mathcal{O}(10^{15})$ moun decays in phase 1 and one in $10^{16}$ muon decays in phase 2, which is four orders of magnitude more sensitive than the previous measurement conducted by the...
The Muon-to-Electron-Conversion (Mu2e) Experiment is a high-precision, intensity-frontier experiment being developed at Fermilab which will search for coherent, neutrino-less muon to electron conversion in the presence of an atomic nucleus. Such a process would exhibit charged lepton flavor violation (CLFV), which has not yet been observed. Continuing the search for CLFV, Mu2e will improve the...
COMET is an experiment at J-PARC, Japan, which will search for neutrinoless conversion of muons into electrons in the field of a nucleus ($ฮผ^โ + N \to e^โ + N$); a lepton flavor violating process.

The international GENIE Collaboration maintains and develops an extensive software suite to meet the simulation needs of the broad neutrino community. GENIE develops a universal event generator simulating neutrino interactions from MeV to PeV energy scales, and a global analysis of neutrino scattering data used for model characterization, tuning and uncertainty evaluations. In recent years,...
The NEUT generator has a long, storied history. Originally written to predict neutrino induced backgrounds for the Kamioka Nucleon Decay Experiment (Kamiokande), it is now relied upon by T2K to simulate signal and background interactions for their oscillation and neutrino scattering cross section measurements. Looking to the future, the next-generation Hyper-Kamiokande experiment expects to...
Neutrino oscillation experiments, such as the Tokai to Kamioka (T2K) experiment, are limited by their simulation of accurate neutrino-nucleus interactions. More in-depth theoretical knowledge of neutrino-nucleus interactions are paramount; however, implementing such knowledge in existing event generator frameworks is just as imperative. To evaluate neutrino-nucleus interactions a general...
Simulations of neutrino-nucleus scattering are a critical input to oscillation analyses and various other investigations in high-energy physics. Achieving the physics goals of future experiments will require substantial improvements to the precision of these simulations. In March of this year, a workshop was held at Fermilab that examined several major topics related to future development of...
As neutrino oscillation physics enters the precision era, the modeling of neutrino-nucleus interactions constitutes an increasingly challenging source of systematic uncertainty for new measurements. To confront such uncertainties, a new generation of detectors is being developed to measure the exclusive final state of neutrino interaction. Precise simulations of the nuclear effects on the...
The neutrino community is at an exciting time where new data with higher precision than ever is challenging the empirically based models which have been developed over the last several decades. Understanding this new data requires state of the art theory, leveraging collaboration between the nuclear physics, electron scattering, and neutrino community. One such state of the art model, the...
This talk will present the status of the Bodek-Yang model.
Accurate theory calculations for neutrino-nucleus scattering rates are essential in the interpretation of neutrino experiments, from oscillation measurements to astroparticle physics at neutrino telescopes. In the deep-inelastic (DIS) regime, neutrino structure functions can be reliably evaluated in the framework of perturbative QCD. However, large uncertainties affect these structure...
Global analyses of nuclear Parton distribution functions (nPDFs) play a crucial role in making precise predictions for a wide range of processes in lepton-nucleus (lA), proton-nucleus (pA), and heavy ion collisions (AA). In this context, the inclusion of neutrino deep inelastic scattering (DIS) data is particularly important as it enables an improved flavour separation of the parton...
