Technical Design Report of the Spin Physics Detector at NICA
arxiv(2024)
摘要
The Spin Physics Detector collaboration proposes to install a universal
detector in the second interaction point of the NICA collider under
construction (JINR, Dubna) to study the spin structure of the proton and
deuteron and other spin-related phenomena using a unique possibility to operate
with polarized proton and deuteron beams at a collision energy up to 27 GeV and
a luminosity up to 10^32 cm^-2 s^-1. As the main goal, the
experiment aims to provide access to the gluon TMD PDFs in the proton and
deuteron, as well as the gluon transversity distribution and tensor PDFs in the
deuteron, via the measurement of specific single and double spin asymmetries
using different complementary probes such as charmonia, open charm, and prompt
photon production processes. Other polarized and unpolarized physics is
possible, especially at the first stage of NICA operation with reduced
luminosity and collision energy of the proton and ion beams. This document is
dedicated exclusively to technical issues of the SPD setup construction.
