NuWro is a versatile Monte Carlo neutrino event generator, applicable for simulations in the energy range of the accelerator-based neutrino oscillation experiments. Since 2005, the theoretical group of the University of Wrocław, Poland, has been extensively working on its development, successfully comparing to various neutrino cross section measurements. NuWro is a vital tool for event...
NEUT is a neutrino-nucleus interaction simulation program library and used for the analyses of Super-K and T2K. Recently, NEUT is also used to simulate pion interactions with the nucleus in the detector simulation. In order to make the users access various functions in NEUT, we have started a project to design
a set of new APIs for easy access to the implemented total and interaction...
The next generation of neutrino oscillation experiments rely on the precise understanding of neutrino interactions in a wide energy range. The GENIE collaboration is constantly engaged in an effort to improve interaction models and fit them against available datasets. A lot of effort is going into pion producing processes, so far focusing on the resonant component of the pion production. This...
The generation of accurate neutrino-nucleus cross section models needed for neutrino oscillation experiments requires simultaneously the description of many degrees of freedom and precise calculations to model nuclear responses. The detailed calculation of complete models makes the Monte Carlo generators slow and impractical. We present exhaustive neural importance sampling, a method based on...
We report on an update (2021) of a phenomelogical model for inelastic neutrino- and electron- nucleon scattering cross sections using effective leading order parton distribution functions with a new scaling variable ξw. Non-perturbative effects are well described using the ξw scaling variable in combination with multiplicative K factors at low Q2. The model describes all inelastic charged...
MicroBooNE is a liquid argon time projection chamber that operates in the Booster Neutrino Beam at Fermilab. The detector provides high-resolution imaging of neutrino interactions with a low threshold and full angular coverage. Thanks to a high event rate and several years of continuous operation, the MicroBooNE collaboration has obtained the world's largest dataset of neutrino-argon...
The MicroBooNE detector is the world's longest-running liquid argon time projection chamber (LArTPC), currently installed in the Booster Neutrino Beam at Fermilab. One of the primary physics goals of MicroBooNE is to perform detailed studies of neutrino-argon scattering cross sections, which are critical for the success of future neutrino oscillation experiments. At neutrino energies relevant...
Charged-current quasielastic scattering is the signal process in modern neutrino oscillation experiments. It also serves as the main tool for the reconstruction of the incoming neutrino energy. Exploiting effective field theory, we factorize neutrino-nucleon quasielastic cross sections into soft, collinear, and hard contributions. We evaluate soft and collinear functions from QED and provide a...
The data on tau neutrino is very scarce, only a few experiments have detected its interactions. At FNAL beam dump experiment DONUT, tau neutrino interaction cross-section was directly measured with a large systematical (~50%) and statistical (~30%) errors. The main source of systematical error is due to a poor knowledge of the tau neutrino flux. The effective way for tau neutrino production is...
The advent of high precision measurements of neutrinos and their oscillations calls for accurate predictions of their interactions with nuclear targets utilized in the detectors.
Achieving a comprehensive description of the different reaction mechanisms active in the broad range of energy relevant for oscillation experiments is a formidable challenge for both particle and nuclear Physics. I...
T2K is a long baseline neutrino oscillation experiment, located in Japan. A muon (anti)neutrino beam peaked at 600 MeV is produced in the J-PARC facility and measured by near detectors and the Super-Kamiokande far detector. The main goal is to measure the neutrino oscillation parameters. T2K can run in both neutrino and antineutrino mode, enhancing the sensitivity to charge-parity violation...
The T2K experiment is a long-baseline neutrino oscillation experiment, based in Japan, which measures the oscillation probability of muon neutrinos produced at the JPARC facility, and detected at Super-Kamiokande. A detailed understanding of neutrino-nucleus cross sections is essential to measuring neutrino oscillation parameters. The off-axis near detector ND280 is used to measure a variety...

In this talk, we will discuss the potential to prove "generalized neutrino interactions", exotic new physics interactions beyond the Standard Model, in the coherent-elastic neutrino-nucleus scattering (CE$\nu$NS) experiments in light of the latest COHERENT- CsI, and LAr data. We will discuss that how CE$\nu$ES processes could constrain these exotic new physics effective couplings, and the...
The current and next generation experiments looking for coherent elastic neutrino-nucleus scattering (CEvNS) and neutrino-electron scattering are a unique tool for exploring exotic neutrino physics via nuclear and electron recoil measurements. In this talk, I will discuss the potential of such experiments in opening new directions on rare event searches beyond the neutrino sector. In...
