The B±-Meson Production in High Energy pp Collisions in the Color Dipole Transverse Momentum Representation

The color dipole formalism in the transverse momentum framework together with the unintegrated gluon distributions is considered to obtain the $B^{\pm}$ differential cross sections in $pp$ collisions. The theoretical predictions for the B^±-meson production assume the center-of-mass energy of the Large Hadron Collider and the rapidities available at the LHCb experiment. The results are compared with the corresponding measurements in terms of the meson transverse momentum.

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.
