Associated $W^{\pm}D^{(*)}$ production at the LHC and prospects to observe double parton interactions

TL;DR

This paper investigates the production of $W^{}D^{(*)}$ at the LHC, showing that double parton scattering dominates and can be used as an indicator of double parton interactions, with predictions aligning with ATLAS data.

Contribution

It provides the first detailed analysis of same-sign $W^{}D^{}$ production as a probe for double parton interactions at the LHC.

Findings

Double parton scattering dominates over single scattering in $W^{}D^{}$ production.

Predictions agree reasonably well with ATLAS experimental data.

The process can serve as an indicator of double parton interactions.

Abstract

Associated production of charged gauge bosons and charged charmed mesons at the LHC is considered in the framework of $k_T$-factorization approach. Theoretical predictions are compared with ATLAS data, and reasonably good agreement is found. Predictions on the same-sign $W^{\pm}D^{\pm}$ configurations are presented including single parton scattering and double parton scattering contributions. The latter are shown to dominate over the former, thus giving evidence that the proposed process can serve as another indicator of double parton interactions.
