The Mu2e experiment will search for the CLFV process of coherent, neutrinoless $\mu^- \rightarrow e^-$ conversion in the field of an Al nucleus. The expected signal is a 104.97 MeV monochromatic conversion electron (CE). The signature feature of Mu2e is the superconducting solenoidal magnetic system that produces a high intensity pulsed muon beam. One of the backgrounds to the CE search is...
The LHC offers a unique environment to study neutrinos in the intermediate energy range between those produced in fixed-target accelerator experiments and high-energy astrophysical sources. The FASER experiment takes advantage of the intense, highly collimated flux of light hadrons produced at Interaction Point 1 (IP1) to probe high-energy collider neutrinos. Using the electronic detector...
The "Buddy System" Program is a networking initiative that encourages new connections between collaborators to be formed during collaboration meetings. A survey is sent before upcoming meetings, asking both in-person and virtual attendees who are interested to fill out the form to be matched with 1-2 other collaborators. Based on the responses, including a ranking system for how they want the...

T2K is a long-baseline neutrino experiment stationed in Japan, with the primary goal of measuring $δ_{cp}$ via comparison of $ν_μ→ν_e$ and $ν^{-}_μ→ν^{-}_e$ oscillation. The ND280 off-axis near detector samples the neutrino beam before oscillation occurs, and allows for...
The Tokai to Kamioka (T2K) experiment is a long-baseline neutrino oscillation experiment aiming to measure CP-violation in the lepton sector. So far, T2K has shown results that disfavor CP conservation with a confidence level of 90%. One of the major systematic uncertainties in the current oscillation analysis is the electron-neutrino cross-section. To reduce these uncertainties, the near...
Neutrino experiments rely on complex and computationally expensive detector simulations to predict observable quantities from neutrino interaction models. The significant cost of these simulations limits the feasibility to generate new detector-level events for changes in the interaction model. An approach often used is to produce a new simulation of only the interaction model, which is much...
T2K (Tokai to Kamioka) is a long-baseline neutrino experiment based in Japan, designed to measure neutrino oscillation parameters, including $ \theta_{13} $, $ \delta_{CP}$, $\theta_{23}$, and $\Delta m^2_{32}$. These parameters are determined by studying electron neutrino appearance probabilities and muon neutrino survival probabilities. In recent years, T2K has undergone significant upgrades...
The Neutrino Platform at CERN hosts large-scale prototypes for DUNE’s Far Detector, aligned with the SPS beamline pointed towards the North Area.
The 400 GeV/c SPS protons impacting on the T2 target area may produce exotic particles that could travel ~700 meters to the detectors, in addition to a substantial flux of neutrinos.
Simulations of the neutrino flux predict that thousands of...
Hyper-Kamiokande (Hyper-K) is a next-generation Water Cherenkov detector designed to study neutrino properties with exceptional accuracy. Precision measurements of neutrino oscillations, charge-parity (CP) violation, atmospheric and solar neutrino studies, as well as proton decay searches, are among the key physics goals of Hyper-K, making accurate detector calibration essential for achieving...
Jiangmen Underground Neutrino Observatory (JUNO) is a next-generation 20-kton liquid scintillator (LS) detector currently under commissioning. JUNO is capable of exploring various physics topics including atmospheric neutrino oscillations. While the atmospheric neutrino flux is initially composed exclusively of muon and electron neutrinos, a large number of them are expected to oscillate to...
The T2K experiment is a long-baseline neutrino oscillation experiment based in Japan, with the primary goal of measuring CP violation through comparing neutrino and antineutrino oscillations. The primary off-axis near detector, ND280, observes the neutrino beam before oscillation, and has the important role of constraining neutrino-nucleus interactions. This is a leading source of systematic...
For current and upcoming accelerator-based neutrino oscillation experiments, a precise understanding of neutrino-nucleus interactions is crucial to attaining the desired sensitivity. Insufficient knowledge of the energy carried by undetected particles, particularly neutrons, produced in neutrino-nucleus interactions can distort the reconstructed neutrino energy spectrum and introduces bias in...
Jiangmen Underground Neutrino Observatory (JUNO) is a large-scale neutrino experiment located 700 meters underground in Southern China. JUNO is capable of detecting multiple types of neutrinos including atmospheric neutrinos which can undergo both charged current (CC) and neutral current (NC) interactions in the detector. In addition to the standard 3-flavor oscillation measured by CC...
The Mu3e experiment is dedicated to observing charged lepton flavour violation through the neutrino-less decay of a muon to two positrons and an electron. The experiment is located around the Compact Muon Beam Line (CMBL) at the Paul Scherrer Institut, which produces muons at a rate of $10^{8}$ Hz. The experiment aims to observe the decay or exclude a branching ratio greater than $10^{-16}$....
Next-generation neutrino detectors will require new simulation and reconstruction software. For water and scintillator-based neutrino detectors, RATPAC is a leading simulation framework. The latest release,
RATPAC-TWO, brings several enhancements over the original version, improving both the usability and collaboration potential between experiments. With the 30-tonne BUTTON experiment at...
Since 1983 the Italian groups collaborating with Fermilab (US) have been running a 2-month summer training program for Master students. While in the first year the program involved only 4 physics students, in the following years it was extended to engineering students. Many students have extended their collaboration with Fermilab with their Master Thesis and PhD.
The program has involved...
The upcoming Hyper-Kamiokande experiment is a next generation water Cherenkov detector based in Japan. Using an upgraded JPARC neutrino beam, Hyper-K aims to make precision measurements of the CP violating phase $\delta_{CP}$, along with neutrinos from astrophysical sources, and proton decay. With a fiducial volume approximately eight times larger than its predecessor Super-Kamiokande,...
We study the dependence of neutrino-induced $\gamma/\pi^0$ production ($\stackrel{ {(-)}}{\nu_\mu} + A \to \stackrel{ {(-)}}{\nu_\mu}(\mu) +\gamma/\pi^0 + X$) on the target nucleus A, at the $\Delta$ resonance mass region.
We predict the ratio of the $\gamma / \pi^0$ production rates in NC and CC interactions and for $\nu_\mu$ and $\bar \nu_\mu$ beams:
- Argon target: $\sim$3.1\%...
Precise measurements of neutrino oscillations in long-baseline experiments depend on an accurate understanding of neutrino beam properties and neutrino–nucleus interactions—two dominant sources of systematic uncertainty. To reduce these uncertainties, the ND280 near detector of the T2K neutrino experiment in Japan has undergone a major upgrade designed to provide full polar angle acceptance,...
