Scientists found the elusive “God particle” or Higgs Boson with the help of the Large Hadron Collider (LHC) ten years ago. On July 5, the LHC was turned on for the third time, which led to the discovery of three “exotic particles.” Scientists found a “pentaquark” and the first pair of “tetraquarks” using the world’s largest and most powerful particle collider at CERN, the European particle physics laboratory in Geneva.

The LHC was turned back on after three years in April. On July 5, it was given a level of energy that had never been seen before. Since then, protons have been smashing together at almost the speed of light, which could lead to “new” physics that goes beyond the Standard Model.

About LHC

CERN, which stands for the European Council for Nuclear Research, describes the Large Hadron Collider as a 27-kilometre ring of superconducting magnets with a number of structures that speed up the particles along the way. It took about 10 years to build the LHC, which is said to have cost about $4.75 billion in total.

The program is paid for by the countries that are part of CERN. Germany, the UK, Italy, France, and Spain pay just over 70% of the annual budget. The governments of the United States, India, and Russia, as well as universities and other large organizations, have also given money.

What was discovered?

Scientists at CERN turned on the LHC in July after upgrading and fixing it for more than three years. On July 5, they found “a new type of “pentaquark” and the first pair of “tetraquarks,” which included a new type of “tetraquark.” Quarks are the most basic parts of matter. Most of the time, they are inside protons and neutrons, which are the particles at the centre of every atom in the universe.

Most protons and neutrons are made up of two different kinds of quarks. We call these “up” and “down” quarks. The charm and top quarks are the heavier copies of the up quark, and the strange and bottom quarks are the copies of the down quark. Most hadrons, like the protons and neutrons in an atom’s nucleus, are made up of two or three quarks that come together in pairs or threes. But they can also join together to make particles with four or five quarks. These are called tetraquarks and pentaquarks.

Newest Discoveries

The new things found by the LHC are a pentagon with a charm quark, a charm antiquark with an up quark and a down quark, and the strange quark. It is the first one to have a strange quark. Scientists at CERN say that this is very important because it is statistically significant by 15 standard deviations, which is more than the five standard deviations needed to claim an observation in particle physics.

A CERN press release says that the second type is a tetraquark with two electric charges. It is made up of a charm quark, a strange antiquark, an up quark, and a down antiquark. It is an open-charm tetraquark. One of the two new tetraquarks is made up of a charm quark, a strange antiquark, an up quark, and a down antiquark (left), and the other is made up of a charm quark, a strange antiquark, an up antiquark, and a down quark.

The fundamental force-carrying particle of the Higgs field, which gives other particles their mass, is known as the Higgs boson. The theory for this field was first put forth in the middle of the 1960s by Peter Higgs, after whom the particle is named, and his associates.

On July 4, 2012, scientists at the Large Hadron Collider (LHC), the world’s most powerful particle accelerator, based at the European Particle Physics Laboratory CERN in Switzerland, made the particle’s ultimate discovery. The LHC finalised the standard model of particle physics, the best account we have of the subatomic universe, by confirming the existence of the Higgs field and the mechanism that gives origin to mass.

WHAT IS THE HIGGS BOSON(The God Particle)?

According to CERN, the Higgs boson has a mass of 125 billion electron volts, making it 130 times more massive than a proton (opens in new tab). It also has no charge and no spin, making it the quantum mechanical counterpart of angular momentum. The only elementary particle without spin is the Higgs Boson.

When particles interact with one another, a boson, which is a “force carrier” particle, is involved. A boson is transferred during this contact. For instance, a photon—the particle that carries electromagnetic fields’ force—is exchanged when two electrons come into contact.

A boson can alternatively be characterised as a wave since quantum field theory uses wave mechanics to describe the microscopic world and the quantum fields that fill the world.

WHY IS THE HIGGS BOSON CALLED THE ‘GOD PARTICLE?

When the Higgs boson was discovered, particularly as a result of the popular media, the name “the God Particle” became firmly established. This is frequently attributed to Nobel Prize-winning physicist Leon Lederman, who, in anger about how difficult it was to discover, referred to the Higgs boson as the “Goddamn Particle.”  Lederman originally intended for his book on the Higgs boson to be titled “The Goddamn Particle,” but the publishers changed it to “The God Particle,” creating a problematic religious connotation that persists to this day.

HIGGS BOSON DISCOVERY AND THE STANDARD MODEL

It takes more than just setting up a detector and waiting for the Higgs boson to be discovered. Only in the high-energy circumstances of the early universe did these particles exist. This implies that these high-energy circumstances must be reproduced and Higgs bosons must be produced before this particle can be detected. By accelerating protons to almost light speed and colliding them, the LHC achieves this.

A cascade of particles is produced as a result, and these soon break into lighter ones. Instead of being directly observed because it decays too quickly, the Higgs boson was discovered by looking for particle decays that pointed to a particle without a spin and fitted theoretical expectations for this missing boson.

On July 4, 2012, the Higgs boson’s discovery was announced at CERN in Geneva. The Higgs boson was actually identified as the particle that had been observed in March of the following year. The discovery of the Higgs boson completed this picture of the subatomic world by revealing this article, which was predicted by the standard model. The Higgs boson’s special qualities may be able to provide light on some of the unanswered questions surrounding this theory, including the nature of dark matter.
