Title: e+ e- -> nu nubar H 的电弱辐射修正

Abstract: The complete electroweak O(alpha) radiative corrections to the Higgs-boson production processes e+ e- -> nu_l anti-nu_l H (l=e,mu,tau) are calculated in the electroweak Standard Model. For e+ e- -> nu_e anti-nu_e H, where ZH production and W-boson fusion contribute, both production channels are added coherently. The calculation of the corrections is described in some detail including, in particular, the treatment of the Z-boson resonance in the ZH-production channel. The discussion of numerical results focusses on the total cross section as well as on angular and energy distributions of the Higgs boson. In the Gmu-scheme, the bulk of the corrections is due to initial-state radiation. The corrections turn out to reduce the total cross section by \sim 10% for high energies, where the W-boson fusion dominates. In this region, the corrections depend only weakly on the energy and the production angle of the Higgs boson. Based on an analysis of the leading universal corrections, a simple improved Born approximation is introduced. This approximation describes the corrected cross section within about 3%.

Abstract: 在电弱标准模型中，计算了Higgs玻色子产生过程e+ e- -> nu_l anti-nu_l H (l=e,mu,tau)的完整电弱O(alpha)辐射修正。 对于e+ e- -> nu_e anti-nu_e H，其中ZH产生和W玻色子融合起作用，两种产生通道是相干相加的。 修正的计算被详细描述，特别是ZH产生通道中Z玻色子共振的处理。 数值结果的讨论集中在总截面以及Higgs玻色子的角度和能量分布上。 在Gmu方案中，修正的主要部分来自于初态辐射。 修正结果显示，在高能情况下，总截面减少了\sim 10%，此时W玻色子融合占主导地位。 在这个区域，修正仅弱依赖于能量和Higgs玻色子的产生角度。 基于对主要普遍修正的分析，引入了一种简单的改进的Born近似。 该近似能够以约3%的精度描述修正后的截面。
