Abstract:
A new polarization control mode called a Spin Transparency (ST) mode is currently being actively developed for the NICA collider. The ST mode can be provided by inserting two solenoidal Siberian snakes into opposite straights of the NICA collider. The ST mode allows one to develop a completely new approach to the measurement of the EDMs of both proton and deuteron. The idea of the method is to use the significant enhancement of the EDM signal by the interaction of the EDM with magnetic elements of the NICA ring, which has an interference effect. A unique feature of this technique is the conceptual capability of measuring the EDM signal in the whole energy range of NICA without introducing additional electric fields using only the fields of the collider’s correcting dipoles. The methodology of searching for EDM protons is discussed, and estimates of the minimum EDM values that can be measured at the NICA collider are given.
