M. B. Gay Ducati, G. G. Silveira

摘要:

本文研究了在大型强子对撞机(LHC)上质子-质子碰撞中,在中心排他衍射过程中,在次领先级精度下的希格斯玻色子的产生。通过衍射因式分解的Ingelman-Schlein方法分析了双Pomeron交换的产生过程,考虑到部分子含量的Pomeron的衍射部分子分布函数提供的H1合作。因此,我们估计的生产截面的希格斯玻色子,以及它的快度分布的不同能量的LHC。此外,我们包括在我们的计算,这是在最近的工作中研究的间隙生存概率,并预计在14 TeV的能量制度的1%和5%之间的范围内。结果发现,在7(14)TeV能量下,产生的截面约为0.3- 0.8(1.2- 3.7)fb,与双光子和Balitsky-Fadin-Kuraev-Lipatov Pomeron机制的预测数量级相同。因此,在自旋宇称性质的选择规则下,排他性产生是LHC探测希格斯玻色子玻色子的一个很有前途的途径。

英文摘要:

The Higgs boson production is investigated in proton-proton collisions at next-to-leading-order accuracy in central exclusive diffractive processes at the LHC. The production process by the double Pomeron exchange is analyzed in the diffractive factorization through the Ingelman-Schlein approach, taking into account the parton content of the Pomeron by the diffractive partonic distribution function provided by the H1 Collaboration. Hence, we estimate the production cross section of the Higgs boson as well as its rapidity distribution for distinct energies of the LHC. Also, we include the gap survival probability in our calculation, which is studied in recent works and expected to lie in the range between 1% and 5% for the energy regime of 14 TeV. As a result, we found a production cross section of about 0.3--0.8 (1.2--3.7) fb at 7 (14) TeV, being of the same order as predicted by the two-photon and the Balitsky-Fadin-Kuraev-Lipatov Pomeron mechanisms. Therefore, assuming the selection rules of spin-parity properties, the exclusive production is a promising channel for the Higgs boson detection in the LHC.
