在大费曼x上的希格斯强子产生

Higgs Hadroproduction at Large Feynman x

Stanley J. Brodsky, Alfred S. Goldhaber, Boris Z. Kopeliovich, Ivan Schmidt

摘要:

我们提出了一种新的机制,在包容强子碰撞中的希格斯玻色子的生产,它利用重夸克的质子波函数的存在。在这些包容性反应中,希格斯玻色子玻色子获得了重夸克和反夸克的动量,因此携带了抛射体80%或更多的动量。我们预测的横截面${d σ/d x_F}(p \bar p \to H X)$的标准模型希格斯粒子来自内禀底部福克态的生产是为了150 FB在大型强子对撞机的能量,峰值在该地区的$x_F \sim 0.9$。我们的估计表明,相应的截面来自胶子-胶子融合在$x_F = 0.9$是相对可以忽略不计的,因此,从本征底部的峰值应该是清晰可见的实验与前向检测能力。预测的横截面为生产的标准模型希格斯来自本征重夸克福克态的质子是足够大的,在Tevatron和大型强子对撞机的检测可能。

英文摘要:

We propose a novel mechanism for the production of the Higgs boson in inclusive hadronic collisions, which utilizes the presence of heavy quarks in the proton wave function. In these inclusive reactions the Higgs boson acquires the momenta of both the heavy quark and antiquark and thus carries 80% or more of the projectile's momentum. We predict that the cross section ${d σ/d x_F}(p \bar p \to H X)$ for the inclusive production of the Standard Model Higgs coming from intrinsic bottom Fock states is of order 150 fb at LHC energies, peaking in the region of $x_F \sim 0.9$. Our estimates indicate that the corresponding cross section coming from gluon-gluon fusion at $x_F = 0.9$ is relatively negligible and therefore the peak from intrinsic bottom should be clearly visible for experiments with forward detection capabilities. The predicted cross section for the production of the Standard Model Higgs coming from intrinsic heavy quark Fock states in the proton is sufficiently large that detection at the Tevatron and the LHC may be possible.
