Philosophical perspectives on ad hoc hypotheses and the Higgs mechanism

TL;DR

This paper analyzes the critique of the Higgs mechanism as ad hoc in particle physics, exploring its conceptual basis and implications of recent experimental discoveries.

Contribution

It offers a philosophical analysis of the ad hoc critique against the Higgs mechanism, clarifying its conceptual foundations and evaluating recent experimental findings.

Findings

The ad hoc critique is based on implicit assumptions rather than clear definitions.

Recent discovery of a Higgs-like particle impacts the critique of ad hocness.

The critique is rooted in methodological principles of scientific practice.

Abstract

We examine physicists' charge of ad hocness against the Higgs mechanism in the standard model of elementary particle physics. We argue that even though this charge never rested on a clear-cut and well-entrenched definition of "ad hoc", it is based on conceptual and methodological assumptions and principles that are well-founded elements of the scientific practice of high-energy particle physics. We further evaluate the implications of the recent discovery of a Higgs-like particle at the CERN's Large Hadron Collider for the charge of ad hocness against the Higgs mechanism.
