  1. N. Rossiyskaya ADVANCED STUDIES INSTITUTE SYMMETRIES AND SPIN SPIN-Praha-2013 and NICA-SPIN-2013 DY Background studies for NICA/SPD Prague 9 July 2013

  2. Introduction Start with some numerical estimations on cross sections which to be measured with SPD 1) Cross section NICA kinematics: It is important to control and minimization the background to DY reactions. Also studies is very important and essential for SPD design development .

  3. Introduction Also BG studies is very essential to make a wider range on lepton pairs invariant mass, to enlarge statistics for DY reactions 2) Kinematics range Fermilab E866

  4. Sources Present the preliminary list of main sources of background to be considered. The last 4 sources are important for SPD design and optimizations

  5. Sources PHENIX - K and π decays

  6. Sources

  7. Conclusions • Source of DY background are preliminary defined • DY background studies are in connected with SPD design • Analysis is in progress • Welcome to collaboration!!!
