What Actually is “Higgs Boson” Or “The God Particle”.

Higgs Boson
The Higgs Boson and the Higgs Mechanism became a cornerstone of the Standard Model of particle physics. The Higgs boson is the particle associated with the Higgs field, an energy field that transmits mass to the things that travel through it.This theory may be a little hard to digest if you’re totally unfamiliar with particle physics,so lets get familiar with some of the basic fundamentals about this particle:-

·         To know this we must examine one of the most prominent theories describing how the "cosmos works" which is given by the standard model.

·         we know that there are 4 fundamental forces –gravitational, electromagnetic, strong and weak nuclear forces out of these four the weak force and the electromagnetic forces can be described within the same theory, which forms the basis of the standard model which implies that electricity, magnetism, light and some types of radioactivity are all manifestations of a single underlying force known as the electroweak force.

·         There are also 12 fundamental particles of matter  these 12 fundamental particles of matter describes the 12 fermions that make up the basic set of particles. These 12 fermions are further divided into two sets of six quarks and six leptons. Hence Lepton and Quarks are called as the basic building block.

·         The Quarks make up protons and neutrons while members of the Lepton family include the electron and the electron neutrino, its neutrally charged counterpart.

·         The six Quarks are called up, down, strange, charm, top and bottom.
·         The Six Leptons are called the electron, electron neutrino, muon, muon neutrino, tau and tau neutrino.

·         There are also the force carrying particles called bosons. They are photons which responsible for the electromagnetic force, W and Z bosons that cause the weak force and gluons that result in the strong force. There may also be a boson caused the Higgs boson that would help to explain gravity.

·         In particle physics, the Higgs mechanism is a kind of mass generation mechanism, a process that gives mass to elementary particles. According to this theory, particles gain mass by interacting with the Higgs field that permeates all space


The four fundamental forces has a corresponding carrier particle, or boson, that acts upon matter .Now think each of the four fundamental ones has its own specific bosons. Electromagnetic fields, for instance, depend on the photon to transit electromagnetic force to matter. Physicists think the Higgs boson might have a similar function -- but transferring mass itself.

Think for a moment of time if all particles have no inherent mass, but instead gain mass by passing through a field? This field, known as a Higgs field, could affect different particles in different ways. Photons could slide through unaffected, while W and Z bosons would get bogged down with mass. In fact, assuming the Higgs boson exists, everything that has mass gets it by interacting with the all-powerful Higgs field, which occupies the entire universe. Like the other fields covered by the standard model, the Higgs one would need a carrier particle to affect other particles, and that particle is known as the Higgs boson.To test the existence of Higgs particle and Higgs Field the particle accelerators came into picture which are known as the Large Hadron collider which shoots beams of protons into each other. When they collide, they create super-high-energy mash-ups that spew out subatomic particles. From time to time, a Higgs boson might be one of those particles.

 Just after the big bang the Higgs field was zero, but as the universe cooled and the temperature fell below a critical value, the field grew spontaneously so that any particle interacting with it acquired a mass. The more a particle interacts with this field, the heavier it is. Particles like the photon that do not interact with it are left with no mass at all. Like all fundamental fields, the Higgs field has an associated particle – the Higgs boson. The Higgs boson is the visible manifestation of the Higgs field, rather like a wave at the surface of the sea.

According to Einstein Theory Of General Relativity mass is connected to gravitation. The Higgs Boson Mechanism solves the mass enigma but totally ignores gravitation and General Relativity.From this we can say that Higgs Field is nothing but a "Newtonian Field in Spacetime.
