摘    要:在伴有右手中中微子的SU(3)C×SU(3)L×U(1)X(331)模型框架内讨论了Higgs粒子产生过彻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。

关 键 词:331模型  右手中微子  产生截面

Abstract: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 section σ^101 from 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.
Keywords:the 3-3-1 model  right-handed neutrinos  cross section
