On 30 September – 1 October, the remote workshop “Gluon content of proton and deuteron at SPD” was held. The meeting was attended by more than 100 scientists from the world-leading scientific centres.

During the meeting, 22 invited scientific reports were made that covered both theoretical and experimental aspects of the study of polarized and non-polarized gluon structure of nucleons. The report on the project Spin Physics Detector at the NICA collider opened the meeting. Then representatives of scientific organizations of Italy, France, Germany, Japan, the USA, Portugal, the Czech Republic, Greece, Armenia, and scientists from JINR made reports. A part of the reports was about the present state of this field of physics. The other part of reports presented the current status of existing (COMPASS, STAR, PHENIX experiments) and planned (the electron-ion collider in the USA, the LHCspin project at the Large Hadron Collider in CERN, the COMPASS++/AMBER experiment) projects aimed to study gluon structure of hadrons. Almost all the reports evoked vivid discussions. Participants of the Workshop actively exchanged views and paid special attention to the application of the accumulated experience in the SPD project and the search for new tasks.

Summing up the results of the Workshop, Head of the SPD project Alexey Guskov said: “This meeting was extremely important for SPD. We had an opportunity to share with the world spin community our ideas and plans, and, most importantly, to get feedback immediately. Now, we understand which plans we can implement, what is expected of us, and what is the common ground of SPD with other projects in this scientific field.”
