开重味介子的单衍射产生

Single diffractive production of open heavy flavor mesons

Marat Siddikov, Ivan Schmidt

摘要:

本文讨论了在$pp$碰撞中,开重味介子和非瞬发粲夸克偶素的单衍射产生。使用色偶极方法,我们发现,单衍射生产构成的0.5- 2%的包容性生产相同的介子。在Tevatron运动学中,我们的理论结果与现有的实验数据是在合理的协议。在LHC运动学中,我们发现横截面足够大,可以通过实验获得。我们还分析了共生强子多重数的依赖性,发现它比包含相同重介子的产生慢得多。

英文摘要:

In this paper we discuss the single diffractive production of open heavy flavor mesons and non-prompt charmonia in $pp$ collisions. Using the color dipole approach, we found that the single diffractive production constitutes 0.5-2 per cent of the inclusive production of the same mesons. In Tevatron kinematics our theoretical results are in reasonable agreement with the available experimental data. In LHC kinematics we found that the cross-section is sufficiently large and could be accessed experimentally. We also analyzed the dependence on multiplicity of co-produced hadrons and found that it is significantly slower than that of inclusive production of the same heavy mesons.
