In recent years, physicists at the Large Hadron Collider (LHC) at CERN, in Europe, made a groundbreaking discovery: the detection of a Higgs boson decaying into a Z boson particle and a photon. This rare decay process provides valuable insights into the nature of the Higgs boson and the universe as a whole.
Understanding the Higgs Boson
To comprehend the significance of this discovery, it is essential to understand the Higgs boson itself. The Higgs boson is a type of subatomic particle known as a boson, which carries the force experienced by other particles as they move through the Higgs field. The Higgs field is believed to exist throughout the universe and is responsible for particles acquiring mass.
Unlike other elementary particles, the Higgs boson has no electric charge and possesses zero spin. It is the only known elementary particle with these properties. The mass of a particle is determined by its interaction with the Higgs boson, with stronger interactions resulting in greater mass.
The Origin of the Name “God Particle”
The term “God Particle” is often associated with the Higgs boson. This nickname originated from Nobel Prize-winning physicist Leon Lederman, who initially referred to it as the “Goddamn Particle” out of frustration due to its challenging detection. However, it was later modified to the “God Particle,” and the name stuck in popular culture.
The Significance of the Higgs Boson
In 1964, Peter Higgs, François Englert, and Robert Brout proposed a new field and mechanism to explain why certain particles possess mass. They theorized that the weak nuclear force carriers, the W and Z bosons, which were believed to be massless, needed to acquire mass to explain their observed behavior.
Their solution involved a new field that spontaneously breaks symmetry, known as the Brout-Englert-Higgs mechanism. This mechanism grants mass not only to the W and Z bosons but also to many other fundamental particles. Without the Higgs field and this mechanism, all elementary particles would move at the speed of light, without the variation in mass that we observe.
The Large Hadron Collider (LHC)
The Large Hadron Collider, built by the European Organization for Nuclear Research (CERN), is the largest science experiment in the world. It functions as a particle collider, accelerating two beams of particles and causing them to collide head-on.
Features of the LHC
- The LHC accelerates hadrons, which are subatomic particles composed of smaller particles.
- It consists of a 27 km long circular pipe that houses two D-shaped magnetic fields created by approximately 9,600 magnets.
- Protons are accelerated through the beam pipe by rapidly switching the direction of the magnetic field, following the principles of special relativity.
Effects of Collisions
When the two beams of energized particles collide, the energy at the point of collision is the sum of the energy carried by the two beams. This enormous amount of energy can coalesce into various subatomic particles, guided by the fundamental forces of nature.
Findings of the LHC
The LHC comprises nine detectors located at different points along the beam pipe, which study particle interactions in different ways. Scientists have used the LHC to test predictions of the Standard Model of particle physics, observe exotic particles like pentaquarks and tetraquarks, and gather information about extreme natural conditions, such as those present immediately after the Big Bang.
