高能质子与软pp碰撞中的胶子

Gluons in proton and soft pp collisions at high energies

V. A. Bednyakov, G. I. Lykasov, M. G. Poghosyan

摘要:

在软QCD模型(即夸克-胶子弦模型)下分析了高能pp碰撞中的强子包容谱。除了入射质子中的海夸克分布,我们还考虑了未积分的胶子分布,当胶子横动量增加时,胶子分布具有增加的行为。在LHC能区pp碰撞中心快度区,强子的包含谱和多重数都增加了。

英文摘要:

The hadron inclusive spectra in pp collisions at high energies are analyzed within a soft QCD model, namely the quark-gluon string model. In addition to the sea quark distribution in the incoming proton we consider also the unintegrated gluon distribution that has an increasing behaviour when the gluon transverse momentum grows. It leads to an increase of the inclusive spectra of hadrons and their multiplicity in the central rapidity region of pp collision at LHC energies.
