Radiative corrections in neutral-current (anti)neutrino elastic scattering at energies I: Nucleon targets

Yi Chen, Oleksandr Tomalak, Bing-Song Zou

The paper develops and applies radiative corrections for neutral‑current (anti)neutrino‑nucleon elastic scattering at GeV energies using effective field theory, showing that these…

Nucleon axial-vector form factor and radius from radiatively-corrected antineutrino scattering data

Oleksandr Tomalak, Aaron S. Meyer, Clarence Wret +3

The nucleon axial-vector form factor, , is critical to determine the electroweak interactions of leptons with nucleons. Important examples of processes influenced by are…

Resonance Contributions to Radiative Corrections in Charged-Current Elastic (Anti)Neutrino-Nucleon Scattering at GeV Energies

Oleksandr Tomalak

We present the first evaluation of virtual resonance contributions to the charged-current (anti)neutrino-nucleon elastic scattering at GeV energies, focusing on the dominant $Δ(12…

Reducing Hadronic Uncertainty in Low-Energy Neutral-Current Processes

Oleksandr Tomalak

We analyze the hadronic uncertainty from light-quark loops coupled to (anti)neutrino in low-energy neutral-current (anti)neutrino scattering, estimated at the - permille leve…

Theory of inverse beta decay for reactor antineutrinos

Oleksandr Tomalak

Inverse beta decay (IBD), , is the main detection channel for reactor antineutrinos in water- and hydrocarbon-based detectors. As reacto…
