在tt双轻子衰变道中,利用积分亮度为0.7fb^-1的模拟数据量,通过测量W玻色子衰变末态粒子角分布的方法对其极化进行了模拟研究。最终的测量结果为:F0=0.709±0.066(syst)±0.044(stat),FL=0.297±0.077(syst)±0.026(stat),FR=-0.005±0.033(syst)±0.027(stat)。
In tt dileptonic decay channel, a Monte Carlo data sample with the integral luminosity about 0.7fb^-1 was used to study the W boson polarization by measuring the angle distributions of the final particles from W bosom The result was: F0 = 0.709 ± 0.066(syst) ± 0.044(stat), FL =0.297 ± 0.077(syst) ± 0.026(stat), Fs = - 0.005 ± 0.033(syst) ± 0.027(stat) .
