在伴有右手中中微子的SU(3)CSU(3)L?U(1)X(331)模型框架内讨论了Higgs粒子产生过程e+e-→ZH.结果表明,当新粒子Z′的质量接近质心能量时能对该过程产生明显的修正.在该模型合理的参数空间内,过程e+e-→ZH的总产生截面σ与标准模型(SM)相应值的偏差大于5%,应该能在未来的高能直线对撞机实验中观测到.

In the context of SU(3)C?SU(3)L?U(1)X(331) model with right-handed (RH) neutrinos, we study the Higgsstrahlung process e+e-→ZH and calculate the cross section of this process at leading order. Our numerical results shown that the production cross sections for this process can be significantly large as MZ～√S. With reasonable values of the Z' mass MZ, the deviation of the total production cross sectiou σtolfrom its SM value is larger than 5%, which might be detected in the future high energy linear e+e- collider (LC) experiments. The future LC experiments could test the 331 model with RH neutrinos by measuring the cross section of the process e+e-→ZH.
