Abstract

The creation of new measuring instruments is often accompanied by finding important scientific results. In this paper, we discuss the possibility of solving the problem facing high energy physics for several decades using the future NICA SPD facility. This is a problem of the existence of weak excitations of the deuteron in a highly compressed state, the solution of which is of great importance for understanding phase transitions in cold nuclear matter. The answer to this question can also help to perform a test of the color transparency attenuation mechanism, which has not been possible since the late 1980s. The paper discusses a number of theoretical and experimental indications in favor of the existence of light dibaryon excitations in the deuteron, which are below the pion production threshold, and also indicates requirements for a measuring device necessary for their registration.
