1) Cross section
NICA kinematics:
Tot (pp) ~ 40 b
DY ~ 1.3 nb
Start with some numerical estimations on cross sections which to be measured with SPD
It is important to control and minimization the background to DY reactions.Also studies is very important and essential for SPD design development .
2) Kinematics range
2~ 4 9 /llM Gev c
Fermilab E866 30s Gev
Also BG studies is very essential to make a wider range on lepton pairs invariant mass, to enlarge statistics for DY reactions
The last 4 sources are important for
SPD design and optimizations
Present the preliminary list of main sources of background to be considered.
- K and π decays

• Source of DY background are preliminary defined
• DY background studies are in connected with SPD design
• Analysis is in progress
