Brief annotation and scientific rationale:
The goals of the JINR group in the BESIII project are to study hadronic QCD spectra and search for exotic states, study the production and decays of Charmonium states, search for exotic Charmonium states and charmonium-like structures, and determine c-quark fragmentation functions. The JINR group's participation in the project involves data analysis and development of algorithms for event reconstruction in the BESIII detector using machine learning methods. 

Expected results upon completion of the project:
The project will produce new knowledge about the properties of strong interactions on the Q²~ M²_Jpsi scale. In particular, information will be obtained on the spectrum of exotic light and  charmonium-like states and their properties, as well as on the details of inclusive c-quark production.

Expected results of the project this year:
BESIII data analysis. Development of offline software and analysis tools. Participation in the data taking.

Brief annotation and scientific rationale:
AMBER (Apparatus for Meson and Baryon Experimental Research) is a new experimental facility with a fixed target on the M2 beam line of the CERN SPS. The facility is designed to perform a variety of measurements aimed at addressing fundamental questions of quantum chromodynamics, which are expected to lead to a significant improvement in the understanding of QCD as a modern theory of strong interactions. The proposed measurements cover physics ranging from the smallest Q² values, such as determining the charge radius of a proton in elastic muon-proton scattering, reactions with moderate Q² values for hadronic spectroscopy, and studies of hadronic structure with high Q² using rigid Drell-Yan, Charmonium, and fast photon production processes. The JINR group is responsible for the modernization and operation of the HCAL1 hadron calorimeter and MW1 (Muon Wall 1) high-angle muon identification system. It is also involved, along with a group from the University of Turin, in the production and support of the Bulk Micromegas track detectors that will replace the obsolete multi-wire chambers (MWPCs) in the SAS behind the SM2 magnet.

Expected results upon completion of the project:
Solving the proton radius puzzle. New knowledge of the quark and gluon structure of mesons.  Accurate knowledge of the yield of antiprotons in p-p and p-He processes, essential for the search for dark matter in astrophysical experiments.

Expected results of the project this year:
Participation in the data taking for the Proton Radius Measurement program.

 Participation in R&D for Micromegas detectors.

Data analysis on the antiproton production in p-He interaction.

Preparation of the front-end electronics upgrade to be able to operate in the triggerless mode.

Upgrade of the MW1 muon system.
