摘要

本文介绍了在大型强子对撞机的高能质子-质子对撞中产生双粲介子的研究。考虑到在横动量表示法中发展起来的彩色偶极子形式主义以及双parton散射机制，对不同的D$$D$$介子对的横动量差分截面进行了预测。理论结果涵盖了 LHCb 实验可用的质量中心能量和前向速度。考虑到不同未整合胶子分布的质子-质子结果与在大型强子对撞机上收集到的相应数据进行了比较。

Charmed meson pair production in high-energy pp $$ pp $$ collisions within the QCD color dipole approach

A study of double-charmed meson production in high-energy proton–proton collisions at the Large Hadron Collider is presented. Considering the color dipole formalism developed in the transverse momentum representation along with the double parton scattering mechanism, predictions are made for the transverse momentum differential cross section for different pairs of $D$ -mesons. The theoretical results cover the center-of-mass energy and forward rapidities available by the LHCb experiment. The proton–proton results considering different unintegrated gluon distributions are compared to the respective data collected at the LHC.

期刊介绍： Astronomische Nachrichten, founded in 1821 by H. C. Schumacher, is the oldest astronomical journal worldwide still being published. Famous astronomical discoveries and important papers on astronomy and astrophysics published in more than 300 volumes of the journal give an outstanding representation of the progress of astronomical research over the last 180 years. Today, Astronomical Notes/ Astronomische Nachrichten publishes articles in the field of observational and theoretical astrophysics and related topics in solar-system and solar physics. Additional, papers on astronomical instrumentation ground-based and space-based as well as papers about numerical astrophysical techniques and supercomputer modelling are covered. Papers can be completed by short video sequences in the electronic version. Astronomical Notes/ Astronomische Nachrichten also publishes special issues of meeting proceedings.
