we report the results of a theoretical study of quasielastic electron and neutrino interactions with carbon. our approach takes into account the effects of final-state interactions between the struck nucleon and the residual nucleus, neglected in the impulse approximation, through a generalization of the spectral funct... | improving the accuracy of neutrino energy reconstruction in charged-current quasielastic scattering off nuclear targets |
coherent elastic neutrino-nucleus scattering (cevns) is a standard model process that, although predicted for decades, has only been detected recently by the coherent collaboration. now that cevns has been discovered, it provides a new probe for physics beyond the standard model. we study the potential to probe new phy... | prospects for exploring new physics in coherent elastic neutrino-nucleus scattering |
in this work we study the current bounds from the ceνns process and meson invisible decays on generic neutrino interactions with sterile neutrinos in effective field theories. the interactions between quarks and left-handed sm neutrinos and/or right-handed neutrinos are first described by the low-energy effective field... | general neutrino interactions with sterile neutrinos in light of coherent neutrino-nucleus scattering and meson invisible decays |
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 both in neutrino production and detection, with an arbitrary flavor structure, with all leading wilson coefficients simultaneously present, and wi... | eft analysis of new physics at coherent |
achieving a percentage-level precision measurement of the coherent elastic neutrino nucleus scattering (ceν ns) spectrum requires a robust data processing pipeline which can be characterised with great precision. to fulfil this goal, we present hereafter a new python-based data processing pipeline specifically designed... | development of data processing and analysis pipeline for the ricochet experiment |
