寻找sqrt(s)= 8 TeV质子-质子碰撞中通过WZ衰变到轻子的新共振态

Search for new resonances decaying via WZ to leptons in proton-proton collisions at sqrt(s) = 8 TeV

CMS Collaboration

摘要:

搜索在质子-质子碰撞在sqrt(s)= 8 TeV的奇异粒子衰变通过WZ完全轻子的最终状态,电子,μ子,中微子。该数据集对应于19.5毫微微巴恩斯的积分亮度。未观察到显著超出预期标准模型背景。在95%的置信水平上,给出了由扩展规范模型预测的W'玻色子的产生截面和W' WZ耦合的上界。由这个模型预测的W'玻色子的预期和观测质量极限分别为1.55和1.47 TeV。严格的限制也设定在低比例的人工色模型的范围内的模型参数的假设。

英文摘要:

A search is performed in proton-proton collisions at sqrt(s) = 8 TeV for exotic particles decaying via WZ to fully leptonic final states with electrons, muons, and neutrinos. The data set corresponds to an integrated luminosity of 19.5 inverse femtobarns. No significant excess is observed above the expected standard model background. Upper bounds at 95% confidence level are set on the production cross section of a W' boson as predicted by an extended gauge model, and on the W'WZ coupling. The expected and observed mass limits for a W' boson, as predicted by this model, are 1.55 and 1.47 TeV, respectively. Stringent limits are also set in the context of low-scale technicolor models under a range of assumptions for the model parameters.
