Chapter 1: The Higgs Boson and Its Significance

Recently, a subscriber posed an intriguing question:

“What exactly is the Higgs boson, and what role does the Higgs field play? Why is it referred to as the ‘God particle’?”

Many people are aware of the Higgs boson's discovery, which received significant media attention, yet few truly understand what it is or the concept of bosons in general.

Bosons are essential particles that facilitate interactions among other particles. This means that any forces of attraction or repulsion occurring between particles happen through the exchange of bosons.

Various kinds of bosons exist; for instance, the photon is responsible for electromagnetic interactions, while the gluon mediates strong interactions. The W and Z bosons are associated with weak interactions.

According to contemporary physics, bosons are generally expected to be massless. However, the W and Z bosons possess mass. To clarify this anomaly, British physicist Peter Higgs proposed the existence of a unique field, which was later named the Higgs field. The interaction between the W and Z bosons and this field is what imparts them with mass.

To illustrate this concept, think of Styrofoam balls scattered across a table. A gentle breeze can easily move them, but if you place them on water, their mobility is significantly reduced. In this analogy, the Higgs field represents the water that slows down the movement of the W and Z bosons.

The Higgs bosons are the quanta of this field, and there could be various types of them. These bosons enable the Higgs field to interact with the W and Z bosons. Various theoretical models regarding this boson have emerged, yet none successfully predicted its energy levels.

Section 1.1: The Search for the Higgs Boson

The quest for the Higgs boson was a lengthy and complex journey, requiring scientists to investigate numerous hypotheses. Concurrently, alternative models that did not include the Higgs boson were also being explored, which sparked intense discussions among supporters of both perspectives. Ultimately, in 2012, the first candidate for the Higgs boson was detected at the Large Hadron Collider, exhibiting an energy of 126 GeV. By 2013, further confirmations that this was indeed the Higgs boson were published.

Section 1.2: A Shift in Terminology

In 2015, researchers announced the discovery of two additional types of Higgs bosons, with energies of 700 GeV and approximately 250–450 GeV. American physicist Leon Max Lederman originally dubbed the Higgs boson the “goddamn particle” in his book. However, the publisher preferred a more sanitized title, and thus the Higgs boson became known as the “God particle,” a term that has since permeated popular culture.
