用两体末态检验部分子演化

Testing the parton evolution with the use of two-body final states

S. P. Baranov, H. Jung, A. V. Lipatov, M. A. Malyshev

摘要:

我们考虑在大型强子对撞机条件下产生$b\bar b$夸克和Drell-Yan轻子对,主要关注产生的夸克对的总横动量和出射粒子动量之间的方位角。绘制出末态不变质量的分布图,就可以重建出质子中横动量依赖的部分子密度的全图。我们给出了这些分布在LHC能量下的样子的例子。

英文摘要:

We consider the production of $b\bar b$ quarks and Drell-Yan lepton pairs at LHC conditions focusing attention on the total transverse momentum of the produced pair and on the azimuthal angle between the momenta of the outgoing particles. Plotting the corresponding distributions in bins of the final state invariant mass, one can reconstruct the full map of the transverse momentum dependent parton densities in a proton. We give examples of how can these distributions can look like at the LHC energies.
