DESCRIPTION:Speakers: Salvador Urrea González (IFIC (CSIC-Univ Valencia))
 \nWe study the capabilities of the DUNE near detector to probe deviations 
 from unitarity of the leptonic mixing matrix\, the 3+1 sterile formalism a
 nd Non-Standard Interactions affecting neutrino production and detection. 
 We clarify the relation and possible mappings among the three formalisms a
 t short-baseline experiments\, and we add to current analyses in the liter
 ature the study of the νμ→ντ appearance channel. We study in detail 
 the impact of spectral uncertainties on the sensitivity to new physics usi
 ng the DUNE near detector\, which has been widely overlooked in the litera
 ture. Our analysis show that this plays an important role on the results a
 nd\, in particular\, that it can lead to a strong reduction in the sensiti
 vity to sterile neutrinos from νμ→νe transitions\, by more than two o
 rders of magnitude. This stresses the importance of a joint experimental a
 nd theoretical effort to improve our understanding of neutrino nucleus cro
 ss sections\, as well as hadron production uncertainties and beam focusing
  effects. Nevertheless\, even with our conservative and more realistic imp
 lementation of systematic uncertainties\, we find that an improvement over
  current bounds in the new physics frameworks considered is generally expe
 cted.\n\nhttps://indico.ific.uv.es/event/6178/contributions/15548/
