DESCRIPTION:Speakers: Guillermo Gambini (Universidad Nacional de Ingenieri
 a)\nThe Sirius synchrotron facility at the Brazilian Synchrotron Light Lab
 oratory is a state-of-the-art fourth-generation storage ring capable of pr
 oviding high-intensity 3 GeV electron beams. In this talk\, we propose lev
 eraging this advanced infrastructure to drive high-luminosity electron-pho
 ton collisions by impinging a 1 eV monochromatic laser directly onto the a
 ccelerated beam. This unique collision geometry provides an ideal terrestr
 ial platform to search for the dark photon ($A'$)\, a well-motivated gauge
  boson that acts as a kinetic-mixing portal between the Standard Model and
  an invisible dark sector. By exploiting the Dark Inverse Compton Scatteri
 ng process\, $\\gamma e^{-} \\rightarrow A^{\\prime}e^{-}$\, we can isolat
 e this mediator through missing-energy signatures in the recoil electron s
 pectrum and statistical deficits in the standard Compton photon flux. We w
 ill present our projected sensitivity demonstrating that\, with one year o
 f data acquisition\, this setup can significantly reduce standard backgrou
 nds to probe previously unexplored parameter space\, placing competitive 9
 5% C.L. upper bounds on the kinetic mixing parameter ($10^{-8} \\le \\epsi
 lon \\le 10^{-6}$) for dark photon masses up to 10 keV. Reference: 2603.00
