Explicitly on-shell currents in relativistic mean field models
Alexis Nikolakopoulos, Ryan Plestid
Relativistic mean field models are a useful tool for modeling semi-leptonic scattering and photo production on nuclei. When using free-nucleon currents, it is often claimed that th…
Continuum contribution to charged-current absorption of low-energy on Ar
Steven Gardiner, Pablo Barham Alzás, Alexis Nikolakopoulos +3
Accurate modeling of the absorption of tens-of-MeV on Ar is needed to enable measurements of astrophysical neutrinos using large liquid argon time projection chamber…
Charged-Current Neutrino-Induced Single-Pion Production in the Superscaling Approach and Relativistic Distorted-Wave Impulse Approximation
Jesus Gonzalez-Rosa, Alexis Nikolakopoulos, Maria B. Barbaro +3
In this work, we present a detailed comparison of the SuSAv2 (SuperScaling Approach version 2) and RDWIA (Relativistic Distorted-Wave Impulse Approximation) models with measurement…
Computing neutrino cross sections from Euclidian responses
Alexis Nikolakopoulos, Noemi Rocco
Energy integrated neutrino cross sections are integrals of nuclear responses weighted with kinematic prefactors. We decompose the prefactors into a limited set of functions of ener…
Single pion-production and pion propagation in Achilles
Joshua Isaacson, William Jay, Alessandro Lovato +4
We extend the applicability of Achilles (A CHIcagoLand Lepton Event Simulator) by incorporating the single-pion production mechanism in a fully exclusive fashion. The electroweak i…
Factorized distorted wave calculations for electron, neutrino, and BSM processes
Alexis Nikolakopoulos, Raúl González-Jiménez
We point out that, under certain conditions, the nuclear currents that couple to vector bosons can be written as the trace of the product of two matrices. One contains `nucleon dyn…
