摘要

Abstract

The results of the search for ‘‘dark’’ bosons using the iDREAM neutrino detector at the Kalinin NPP are presented. Based on data on the composition of the VVER-1000 reactor core and the fission fractions of the main fissile isotopes, the spectrum of \(\gamma\) -radiation in the core has been calculated. Assuming that dark bosons can be produced in the reactor core via \(\gamma\) -scattering on electrons and subsequently detected by the iDREAM detector in the inverse process, model-independent experimental constraints on the coupling constant of (pseudo)scalar dark bosons with charged leptons of the Standard Model, \(g_{X}\) , have been established.
