We search for resonant WW or WZ production by using up to 5.4 fb(-1) of integrated luminosity collected by the D0 experiment in run II of the Fermilab Tevatron Collider. The data are consistent with the standard model background expectation, and we set limits on a resonance mass by using the sequential standard model W' boson and the Randall-Sundrum model graviton G as benchmarks. We exclude a sequential standard model W' boson in the mass range 180-690 GeV and a Randall-Sundrum graviton in the range 300-754 GeV at 95% C.L.
我们通过使用费米实验室 Tevatron 对撞机二期运行中 D0 实验收集的 5.4 倍 fb(-1)积分亮度来寻找共振 WW 或 WZ 产生。数据与标准模型背景预期一致，我们使用序贯标准模型 W'玻色子和 Randall-Sundrum 模型引力子 G 作为基准来限制共振质量。我们在 95%置信水平下排除了质量范围在 180-690GeV 之间的序贯标准模型 W'玻色子和范围在 300-754GeV 之间的 Randall-Sundrum 引力子。
