Number of reconstructed primary vertices per event observed in the 2012 Run A data and in the MC simulation.

(Top) The missing ET distribution observed in the 2012 Run A data and in the MC simulation. (Bottom) The (data-simulation)/simulation vs missing ET.

(Top) The component of the hadronic recoil parallel to the Z->mumu direction (u_para) in the 2012 Run A data and in the MC simulation. (Bottom) The (data-simulation)/simulation vs u_para.

(Top) The component of the hadronic recoil perpendicular to the Z->mumu direction (u_perp) in the 2012 Run A data and in the MC simulation. (Bottom) The (data-simulation)/simulation vs u_perp.

(Top) -u_para/q_T as a function of q_T in the 2012 Run A data and in the MC simulation, where q_T is the transverse moment of the dimuons. (Bottom) The (data-simulation)/simulation vs u_perp.

(Top) #sigma(u_perp/q_T) as a function of the number of reconstructed vertices (Nvtx) in the 2012 Run A data, 2011 Run B data, and in the corresponding MC simulation samples. (Bottom) The data/simulation vs Nvtx .
