H + 1 b jet Z + 1 b jet Scott Willenbrock - Te. V 4 LHC@FNAL Q = c, b 8

Zb / Zj = 0. 023 +- 0. 004 +- 0. 003 = 0. 024 +- 0. 008 +- 0. 004 D 0 CDF Agrees with NLO calculation Scott Willenbrock - Te. V 4 LHC@FNAL 9

Z + 2 jets w/ 1 b tag NLO calculation now available Challenge: measure Zbj / Zjj Background to Zh Zbb w/ 1 b tag Next: Wbj Campbell, Ellis, Maltoni, SW Scott Willenbrock - Te. V 4 LHC@FNAL 10
