SCIAMACHY, the Scanning Imaging Absorption spectroMeter for Atmospheric CHartographY has provided measurements of limb-scattered solar radiation in the 220 nm to 2380 nm wavelength range since summer ...
在LEPⅡ及NLC能量下e+e—→bb Z0 和 tt－Z0过程中Higgs粒子的观测效应
最小标准模型 扩展标准模型 双Higgs二重态 Higgs粒子质量 弱电过程 总截面和微分截面
2009/7/6
根据最小标准模型及双Higgs二重态的扩展标准模型理论,计算了LEPⅡ以及NLC能量下e+e—→bb Z0 和 tt－Z0的总截面和微分截面以探求Higgs粒子的观测效应.我们发现,只要Higgs粒子的质量MH≤140GeV,对e+e—→bb Z0的测量就能清楚地提供Higgs粒子的信息.然而对e+e—→tt－Z0,不论Higgs粒子是轻或重,它的效应都被淹没在弱电过程的本底中,没有观测的可能.
