论文摘要
我们研究了LHC Energies的Proton-Proton碰撞中的Charmed $ d^0 $ Meson的$λ_C$ Charmed Baryons的增强。我们模拟了Pythia 8 MC发电机中增强的颜色回连接模型的碰撞事件，并根据不同事件活性分类器的比较使用来提出测量，以识别Charmed-Baryon增强的来源。我们证明，在这种增强的色彩连接方案中，多余的产生主要与基础事件有关，而不是与高摩肌喷气机的生产有关。
We study the enhanced production of $Λ_c$ charmed baryons relative to that of charmed $D^0$ mesons in proton-proton collisions at LHC energies. We simulated collision events with the enhanced color-reconnection model in PYTHIA 8 MC generator and propose measurements based on the comparative use of different event-activity classifiers to identify the source of the charmed-baryon enhancement. We demonstrate that in this enhanced color-reconnection scenario the excess production is primarily linked to the underlying event and not to the production of high-momentum jets.
