Vector boson pair production and trilinear gauge boson couplings - Results from the Tevatron

PDF Version Also Available for Download.

Description

Direct measurements of vector boson pair production processes and trilinear gauge boson couplings have been conducted by the CDF and D0 Collaborations. Preliminary results from searches for anomalous WW/WZ {yields} {mu}{nu} jet jet and WZ {yields} eee{nu} production are presented. 95% CL anomalous coupling limits from previously published D0 results are -0.20< {lambda} < 0.20 ({Delta}{kappa} = 0) and -3.0<{Delta}{kappa} < 0:43 ({lambda} = 0) for {Lambda} = 2000 GeV where the WW{gamma} couplings are assumed to equal the WWZ couplings. Combined D0 + LEP experiment anomalous coupling limits are presented for the #12;rst time. 95% CL limits are -0.16 ... continued below

Description

Direct measurements of vector boson pair production processes and trilinear gauge boson couplings have been conducted by the CDF and D0 Collaborations. Preliminary results from searches for anomalous WW/WZ {yields} {mu}{nu} jet jet and WZ {yields} eee{nu} production are presented. 95% CL anomalous coupling limits from previously published D0 results are -0.20< {lambda} < 0.20 ({Delta}{kappa} = 0) and -3.0<{Delta}{kappa} < 0:43 ({lambda} = 0) for {Lambda} = 2000 GeV where the WW{gamma} couplings are assumed to equal the WWZ couplings. Combined D0 + LEP experiment anomalous coupling limits are presented for the #12;rst time. 95% CL limits are -0.16 < {lambda}{sub {gamma}} < 0:10 ({Delta}{kappa} = 0) and -0.15< {Delta}{kappa}{sub {gamma}}#20; < 0:41 ({lambda} = 0) under the assumption that the couplings are related by the \HISZ" constraints. 95% CL anomalous ZZ{gamma} and Z{gamma}{gamma} coupling limits from D0 are jh{sup Z}{sub 30} j < 0:36 (h{sup Z}{sub 40 = 0) and jh{sup Z}{sub 40} j < 0:05 (h{sup Z}{sub 30} = 0) for {Lambda} = 750 GeV. CDF reports the first observation of a ZZ event. Prospects for Run II are discussed.
