Abstract
The NA64 experiment at the CERN SPS is primarily designed for a search for Light Dark Matter (LDM) particles and corresponding mediators, the most popular of which is a vector boson A' (Dark Photon) kinetically mixed with the ordinary photon. However, other types of mediators and more complex models are also possible. The main search method is a missing energy technique. The sensitivity reached with \(9.37 \times {{10}^{{11}}}\) electrons on its active target allowed to establish the best to-date limits on the LDM models parameters and partly cover the regions predicted by Thermal Dark Matter models that are well cosmologically motivated. Other directions of search for Feebly Interacting Particles (FIP) by NA64 are listed.
期刊介绍：
The journal Fizika Elementarnykh Chastits i Atomnogo Yadr of the Joint Institute for Nuclear Research (JINR, Dubna) was founded by Academician N.N. Bogolyubov in August 1969. The Editors-in-chief of the journal were Academician N.N. Bogolyubov (1970–1992) and Academician A.M. Baldin (1992–2001). Its English translation, Physics of Particles and Nuclei, appears simultaneously with the original Russian-language edition. Published by leading physicists from the JINR member states, as well as by scientists from other countries, review articles in this journal examine problems of elementary particle physics, nuclear physics, condensed matter physics, experimental data processing, accelerators and related instrumentation ecology and radiology.
