论文摘要

希格斯特拉隆横截面的准确确定是未来电子旋律对撞机的主要目标之一。它允许唯一的Higgs玻色子衰变模型独立于HIGGS宽度的独立测量。当前的结果使用后坐力质量形状方法。该技术可以应用于Higgsstrahlung事件,Z Boson腐烂到Muons,电子以及预订中,将其用于夸克。先前的分析中未使用Higgsstrahlung事件构建的样品和中微子。我们在这里提出了一种新方法,即参考样本方法。它将后坐力质量方法扩展到可与TAU和中微子样品一起使用。 该扩展名承诺对包容性Higgsstrahung横截面的模型独立确定,其两个ILC极化方案的不确定性为2.1-2.2%,在$ \ sqrt {s} $ = 250 GEV中,集成的亮度为250 $ \ MATHRM {fb^{fb^{ - 1} $。这表示新方法的应用而没有其他数据收集的方法,其准确性提高了20-30%。

An accurate determination of the Higgsstrahlung cross section is one of the main objectives at a future electron-positron collider. It allows for the only Higgs boson decay model independent measurement of the total Higgs width. Current results use the recoil mass shape method. That technique can be applied to Higgsstrahlung events with Z boson decays into muons, into electrons and, with reservations, into quarks. The samples built from Higgsstrahlung events with Z boson decays into taus and neutrinos are not used in previous analyses. We present here a new method, the reference sample method. It extends the recoil mass method to be usable with the tau and neutrino samples as well. The extension promises a model independent determination of the inclusive Higgsstrahlung cross section with a 2.1-2.2% uncertainty from each of the two ILC polarization scenarios at $\sqrt{s}$=250 GeV with an integrated luminosity of 250 $\mathrm{fb^{-1}}$. This represents an improvement of 20-30% on the accuracy from the application of the new approach without additional data collection.
