Description
In this talk, I present the first implementation in MadGraph5_aMC@NLO for bound-state production, including quarkonium, leptonium, and $B_c$ mesons within Non-Relativistic QCD and Non-Relativistic QED. I focus on the extension of MadGraph5_aMC@NLO to quarkonium states, the simplest bound states in QCD, and describe the capabilities of the new framework for inclusive and associated S-wave quarkonium production in a wide variety of experimental environments at Leading Order (LO). I present a comprehensive benchmarking of the LO implementation in MadGraph5_aMC@NLO against Helac-Onia, demonstrating excellent agreement and validating the approach. I further illustrate the expanded functionality of the tool, enabling phenomenological studies that complement and extend the current state of the art. These developments provide the community with a unified, automated, and efficient framework for bound-state production in QED and QCD, and establish a solid foundation for our future next-to-leading-order extensions.
