# Latest developments in the simulation of final states involving top-pair and heavy bosons

## TL;DR

This paper reviews recent advances in simulating top-quark and vector boson pair final states, focusing on NLO+PS accuracy, off-shell effects, interference, and the MiNLO method for combined processes.

## Contribution

It introduces solutions for fully differential top pair production simulation at NLO+PS, including off-shell and interference effects, and discusses the application of the MiNLO method for multiple boson processes.

## Key findings

- Achieved fully differential top pair production simulation at NLO+PS with off-shell effects.
- Demonstrated the MiNLO method for simultaneous NLO+PS description of $W^+W^-$ and $W^+W^- +$ 1 jet.
- Enhanced accuracy in simulating complex final states involving top quarks and heavy bosons.

## Abstract

I give an overview of recent progress in the simulation of final states involving top-quarks and vector bosons pair. First I'll discuss the recently found solutions needed to simulate fully differential top pair production ($pp\to b\bar{b}$ + 4 leptons) at NLO+PS accuracy, retaining off-shellness and interference effects exactly. In the second part, I'll review the MiNLO (Multi-scale Improved NLO) method, and then show a recent application, namely the simultaneous NLO+PS description of $W^+W^-$ and $W^+W^- +$ 1 jet production.
