$\texttt{history}$ in the making: A tool for NNLO cross sections

TL;DR

This paper introduces the development of the 'history' framework, a tool designed to automate NNLO cross section calculations for hadronic processes, validated for certain processes and applied to predict a new observable in ZH production.

Contribution

The paper presents a novel automated framework implementing a fully-local subtraction scheme for NNLO calculations in hadronic collisions, enabling new precision predictions.

Findings

Validated the framework for quark-antiquark processes

Predicted a new observable in ZH production at NNLO

Demonstrated potential sensitivity to new physics effects

Abstract

In these proceedings, we report on our progress in developing the $\texttt{history}$ framework, which aims to implement the fully-local Nested Soft-Collinear infrared subtraction scheme for the automated phase-space integration of color-singlet production processes in hadronic collisions at NNLO accuracy. We validate our implementation for quark-antiquark-initiated processes and demonstrate a first application of the tool by predicting a novel observable for the inclusive process $pp \to ZH+X$, which may offer sensitivity to potential effects of new physics.
