DESCRIPTION:Speakers: Marco Taoso (INFN Torino)\nWe investigate a dark sec
 tor containing a pair of light non-degenerate scalar particles\, with mass
 es in the MeV-GeV range\, coupled to the visibile sector through heavier m
 ediators.  The heaviest dark state is long-lived\, and its decays offer ne
 w testable signals. We analyze the prospects for detection with the propos
 ed beam-dump facility SHiP\, and the proposed LHC experiments FASER and MA
 THUSLA. Moreover\, we consider bounds from the beam-dump experiment CHARM 
 and from colliders (LEP\, LHC and BaBar).  We present our results both in 
 terms of an effective field theory\, where the heavy mediators have been i
 ntegrated out\, and of a simplified model  containing  a  vector  boson  m
 ediator\,  which  can  be  heavy O(1)  TeV\,  or light O(10)  GeV.  We  sh
 ow  that  future  experiments  can  test  large  portions  of  the paramet
 er space currently unexplored\, and that they are complementary to future 
 High-Luminosity LHC searches.\n\nhttps://indico.ific.uv.es/event/6178/cont
