A study of proton-proton collisions in which two b hadrons are produced in association with a Z boson is reported. The collisions were recorded at a centre-of-mass energy of 7 TeV with the CMS detector at the LHC, for an integrated luminosity of 5.2 inverse femtobarns. The b hadrons are identified by means of displaced secondary vertices, without the use of reconstructed jets, permitting the study of b-hadron pair production at small angular separation. Differential cross sections are presented as a function of the angular separation of the b hadrons and the Z boson. In addition, inclusive measurements are presented. For both the inclusive and differential studies, different ranges of Z boson momentum are considered, and each measurement is compared to the predictions from different event generators at leading-order and next-to-leading-order accuracy\nThe channel fiducial region is defined as:\n- 2e or 2mu, with invariant mass between 81 and 101 GeV, pt>20 GeV, |eta|<2.4.\n- Exactly 2 b-hadrons with pt> 15 GeV, |eta|<2.0.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.69342.v1/t1","@type":"Dataset","description":"Differential cross sections for all p_T^Z, as a function of DeltaR(BB).","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.69342.v1/t2","@type":"Dataset","description":"Differential cross sections for all p_T^Z, as a function of DeltaiPhi(BB).","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.69342.v1/t3","@type":"Dataset","description":"Differential cross sections for all p_T^Z, as a function of minDeltaR(Z,B).","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.69342.v1/t4","@type":"Dataset","description":"Differential cross sections for all p_T^Z, as a function of A(ZBB).","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.69342.v1/t5","@type":"Dataset","description":"Differential cross sections for p_T^Z>50 GeV, as a function of DeltaR(BB).","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.69342.v1/t6","@type":"Dataset","description":"Differential cross sections for p_T^Z>50 GeV, as a function of DeltaiPhi(BB).","name":"Table 6"},{"@id":"https://doi.org/10.17182/hepdata.69342.v1/t7","@type":"Dataset","description":"Differential cross sections for p_T^Z>50 GeV, as a function of minDeltaR(Z,B).","name":"Table 7"},{"@id":"https://doi.org/10.17182/hepdata.69342.v1/t8","@type":"Dataset","description":"Differential cross sections for p_T^Z>50 GeV, as a function of A(ZBB).","name":"Table 8"},{"@id":"https://doi.org/10.17182/hepdata.69342.v1/t9","@type":"Dataset","description":"dsigma, assuming a minimal p_T^Z>x.","name":"Table 9"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1256943?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/69342"}],"inLanguage":"en","name":"Measurement of the cross section and angular correlations for associated production of a Z boson with b hadrons in pp collisions at sqrt(s) = 7 TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1256943?version=1","version":1}
