0011 Plots:
0012 Like Fig. 10 from CMS
0013 Also Fig. 2.2 from sPHENIX proposal (pg56)

0015 ## sPHENIX luminosity ##
0016 -- p+p --
0017 175 pb^-1
0018
0019
0020 -- Au+Au --
0021 10B events for 0-10% in |z|<10
0022 <Ncoll>(0-10%) = 962
0023 AuAu luminosity = 10e9 / 6.8e9 nb = 1.47 nb^-1
0024 (For comparison Run 14 AuAu 200 was 43.9 nb^-1, or ~1.27 pb^-1 for 0-10%)
0025
0026 equivelant nn luminosity:
0027 N_{evt}^{NN} / sigma_NN = N_{evt}^{AA}*Ncoll / sigma_NN
0028 = 10e9 * 962 / 42e9 pb = 229 pb^-1

0031 Use RAA(b-jet)=0.6 (additional inefficiency per jet)
