# Establishing the Isolated Standard Model

## TL;DR

This paper discusses the challenges and necessary steps to definitively establish the Standard Model as isolated, meaning no new physics exists at the weak scale, by assessing current and future experimental and theoretical efforts.

## Contribution

It proposes a quantitative framework to evaluate the status and prospects of confirming the isolated Standard Model, considering broad BSM theories and experimental limitations.

## Key findings

- Current experiments are insufficient to fully verify the ISM.
- Some BSM theories remain unexcluded by existing data.
- Future experimental and theoretical efforts are outlined for robust validation.

## Abstract

The goal of this article is to initiate a discussion on what it takes to claim "there is no new physics at the weak scale," namely that the Standard Model (SM) is "isolated." The lack of discovery of beyond the SM (BSM) physics suggests that this may be the case. But to truly establish this statement requires proving all "connected" BSM theories are false, which presents a significant challenge. We propose a general approach to quantitatively assess the current status and future prospects of establishing the isolated SM (ISM), which we give a reasonable definition of. We consider broad elements of BSM theories, and show many examples where current experimental results are not sufficient to verify the ISM. In some cases, there is a clear roadmap for the future experimental program, which we outline, while in other cases, further efforts -- both theoretical and experimental -- are needed in order to robustly claim the establishment of the ISM in the absence of new physics discoveries.
