摘要:

讨论了高能下希格斯玻色子和重夸克-重反夸克对的排他性双衍射产生.微分分布$c \bar c$在$\sqrt{s}$ = 1.96 GeV和$b \bar b$在$\sqrt{s}$ = 14 TeV的显示和讨论。在几个运动学变量中计算了Higgs产生的不可约前导级$b \bar b $背景。示出的信号与背景比,并提出了几个改进的建议,通过实施削减$b$($\bar b$)的横向动量和rapidities。

英文摘要:

We discuss exclusive double diffractive (EDD) production of Higgs boson and heavy quark - heavy antiquark pairs at high energies. Differential distributions for $c \bar c$ at $\sqrt{s}$ = 1.96 GeV and for $b \bar b$ at $\sqrt{s}$ = 14 TeV are shown and discussed. Irreducible leading-order $b \bar b $ background to Higgs production is calculated in several kinematical variables. The signal-to-background ratio is shown and several improvements are suggested by imposing cuts on $b$ ($\bar b$) transverse momenta and rapidities.
