qq → qqH，H → W+W−过程的独特色流导致中心区域的软胶子辐射受到抑制，这是t t产生或q q → W+W−等主要背景过程所不具备的特征。对于重希格斯玻色子的轻子衰变，H → W+W−→ H +ν ν −ν，我们发现这些背景通常伴随着20-40 GeV范围内的微喷流发射。因此，中央微型喷气式飞机否决权构成了一个强大的背景拒绝工具。它可以被看作是一个半硬部分子水平的快度间隙触发器，即使在高亮度下也能工作。
The distinct color flow of the qq → qqH, H → W+W−process leads to suppressed radiation of soft gluons in the central region, a feature which is not shared by major background processes like t t production or q q → W+W−. For the leptonic decay of a heavy Higgs boson, H → W+W−→ ℓ+νℓ−ν , it is shown that these backgrounds are typically accompanied by minijet emission in the 20–40 GeV range. A central minijet veto thus constitutes a powerful background rejection tool. It may be regarded as a rapidity gap trigger at the semihard parton level which should work even at high luminosities.
