DESCRIPTION:Speakers: Robert Folkenberg Siro (Moscow Institute of Physics 
 and Technology)\nSome extensions of the Standard Model (SM) predict the ex
 istence of fermions with an electric charge much smaller than that of the 
 elementary charge. Such particles\, known as millicharged particles (MCP)\
 , may be produced in nuclear reactors from the interactions between gamma-
 rays and the electrons of reactor materials. In this work\, the MCP flux a
 nd energy deposition distributions at Kalinin Nuclear Power Plant (KNPP) a
 re presented. The considered experiments\, RED-100 (with a two-phase emiss
 ion detector filled with either xenon or argon) and νGeN (with a solid-st
 ate germanium detector) were in exposition at KNPP. The proximity of these
  experiments to high intensity flux of reactor gamma quanta allows for the
  probe of the MCPs by comparing reactor-ON (active reactor) and OFF (react
 or shutdown) data. The expected count rates of MCP interaction with electr
 ons of the sensitive volumes of the aforementioned detectors are further c
 ombined with measured background levels to asses the sensitivity of the ex
 periments to hypothetical reactor-produced MCPs.\n\nhttps://indico.particl
