Descripción
Using an effective field theory approach, we study coherent neutrino scattering on nuclei, in the setup pertinent to the COHERENT experiment. We include non-standard effects in both neutrino production and detection, with an arbitrary flavor structure and all leading Wilson coefficients simultaneously present. The tree main tools of this work are a QFT description of neutrino interactions1, a low energy EFT extended to RH neutrinos and a non-relativistic description of the nucleons. We add to a previous work the presence of Dirac light RH-$\nu$. A concise description of the COHERENT event rate is obtained, alongside twelve generalized weak charges that can be associated (in a sense) with the production and scattering of $\nu_e$, $\nu_\mu$ and $\bar{\nu}_\mu$ on the nuclear target and the nuclear currents in detection. Our results present an explicit form of the new charges in terms of all Wilson coefficients.
Abstract
Using an effective field theory approach, we study coherent neutrino scattering on nuclei, in the setup pertinent to the COHERENT experiment. We include non-standard effects in both neutrino production and detection, with an arbitrary flavor structure and all leading Wilson coefficients simultaneously present. The tree main tools of this work are a QFT description of neutrino interactions1, a low energy EFT extended to RH neutrinos and a non relativistic description of the nucleons. We add to a previous work the presence of Dirac light RH-ν. A concise description of the COHERENT event rate is obtained, alongside twelve generalized weak charges that can be associated (in a sense) with the production and scattering of ν_e, ν_μ and ν_μ on the nuclear target and the nuclear currents in detection. Our results present an explicit form of the new charges in terms of all Wilson coefficients.
