在sqrt{s}=1.96 TeV的ppbar碰撞中反常三规范耦合的极限

Limits on Anomalous Triple Gauge Couplings in ppbar Collisions at sqrt{s}=1.96 TeV

CDF Collaboration

摘要:

本文研究了WW和WZ玻色子产生中的反常三重规范耦合。玻色子对产生于sqrt{s}=1.96 TeV的ppbar碰撞中,数据样本对应于费米实验室Tevatron的CDF II探测器收集的350 pb-1的积分亮度。在这个研究中,一个W衰变为轻子,另一个玻色子(W或Z)衰变为强子。结合先前发表的W γ玻色子产生的CDF测量,在95%的置信水平下,使用截断尺度λ =1.5 TeV,得出ATGC极限为-0.18 < lambda < 0.17和-0.46 < Delta kappa < 0.39。

英文摘要:

We present a search for anomalous triple gauge couplings (ATGC) in WW and WZ boson production. The boson pairs are produced in ppbar collisions at sqrt{s}=1.96 TeV, and the data sample corresponds to 350 pb-1 of integrated luminosity collected with the CDF II detector at the Fermilab Tevatron. In this search one W decays to leptons, and the other boson (W or Z) decays hadronically. Combining with a previously published CDF measurement of Wgamma boson production yields ATGC limits of -0.18 < lambda < 0.17 and -0.46 < Delta kappa < 0.39 at the 95% confidence level, using a cut-off scale Lambda=1.5 TeV.
