This paper addresses the issue of production of charm or bottom quarks in association with a high pT process in hadron hadron collision. These quarks can be produced either as part of the hard scattering process or as a remnant from the structure functions. The latter sums terms of the type (alpha_s log(pT/mq))n. If structure functions of charm or bottom quarks are used together with a hard process which also allows production of these quarks double counting occurs. This paper describes the correct procedure and provides two examples of its implimentation in single top and Drell-Yan at the LHC.

    This paper presents the method of combining parton shower formalism with perturbative calculations (matrix elements) in form of a Monte-Carlo algorithm for the process ggZ 0/γ*b, consistently including the heavy quark masses and overlap removal.

      Particle physics has an ambitious and broad experimental programme for the coming decades. This programme requires large investments in detector hardware, either to build new facilities and experiments, or to upgrade existing ones. Similarly, it requires commensurate investment in the R&D of software to acquire, manage, process, and analyse the shear amounts of data to be recorded. In planning for the HL-LHC in particular, it is critical that all of the collaborating stakeholders agree on the software goals and priorities, and that the efforts complement each other. In this spirit, this white paper describes the R&D activities required to prepare for this software upgrade.
