DESCRIPTION:Speakers: Pablo Muñoz Candela (IFIC\, CSIC-UV)\nWe consider t
 he possible production of a new MeV-scale fermion at the COHERENT\, LZ and
  XENONnT experiments\, and the future DUNE detector. The new fermion\, bel
 onging to a dark sector\, can be produced through the up-scattering proces
 s of neutrinos off the nuclei and the electrons of the detector material\,
  via the exchange of a light mediator. We explore the possibility of gener
 alized interactions\, that is a scalar\, pseudoscalar\, vector\, axial or 
 tensor mediator. We perform a detailed statistical analysis of the COHEREN
 T\, LZ and XENONnT datasets and obtain up-to-date constraints on the coupl
 ings and masses of the dark fermion and mediators. Likewise\, we include s
 ensitivities for the DUNE detector. Finally\, we briefly comment on the st
 ability of the dark fermion.\n\nhttps://indico.ific.uv.es/event/8035/contr
