The transverse momentum Q(T) distribution is computed for inclusive Higgs boson production at sqrt[S]=1.96 TeV. We include all-orders resummation of large logarithms associated with emission of soft gluons at small Q(T). We provide results for Higgs boson and Z* masses from M(Z) to 200 GeV. The relatively hard transverse momentum distribution for Higgs boson production suggests possibilities for improvement of the signal to background ratio.
计算了质心能量√[S]=1.96 TeV时希格斯玻色子单举产生的横向动量Q(T)分布。我们纳入了与小Q(T)时软胶子发射相关的大对数的全阶重整化。我们给出了希格斯玻色子和Z*质量从M(Z)到200 GeV的结果。希格斯玻色子产生的相对硬的横向动量分布表明了改善信号与背景比的可能性。
