Why is higgs boson heavier than proton

This is because the theory of how the particle interacts with the most massive of all observed elementary particles, the top quark, involves corrections at a fundamental quantum level that could result in a Higgs mass much larger than the measured value of GeV. How large? Perhaps as much as sixteen orders of magnitude larger than the measured Higgs mass. Since the Higgs mass is so light, this suggests more particles could exist that cancel the quantum corrections from the top quark and other heavy particles.

In a paper posted online and submitted to the journal Physical Review Letters , the ATLAS collaboration reports results of a combination of searches for a new particle — dubbed a vector-like top quark — that could help keep the Higgs boson light.

Various proposals attempt to cancel out the large quantum corrections to the Higgs boson mass. Many of them involve vector-like top quarks, which are hypothetical particles not predicted by the Standard Model of particle physics. Based purely on first principles, elementary particles should be massless. Some, like photons, do have zero mass; yet others are surprisingly heavy.

Enter the Higgs , which would—in theory—i nteract with these latter particles to make the difference. At the bottom of this page, an analogy is introduced by comparing refractive index and mass, to help to understand how Higgs field works. For light particles such as electrons and neutrinos, traveling through the Higgs field is like running down the street.

For the top quark, which is by far the heaviest particle in the Standard Model, traveling through the Higgs field might feel like wading through a vat of molasses.

At the end of this page we give an analogy between the speed of light depending on the interaction with the medium, and the speed of particles depending on the interaction with the Higgs field through which the particle travel.

Now, they continue to analyze these and new data to understand better the physics of Higgs boson and to reach new areas beyond the Standard Model. This event is consistent with two Z particles decaying into two muons each. Such events are also produced by Standard Model processes without Higgs particles. They are also a possible signature for Higgs particle production, but many events must be analysed together in order to tell if there is a Higgs signal.

A schematic, of two virtual gluons from colliding LHC protons interacting to produce a hypothetical Higgs boson , a top quark, and an antitop quark. These in turn decay into a specific combination of quarks and leptons that is very unlikely to be duplicated by other processes. The precision electroweak measurements pointed to the existence of a light Higgs. Thus the presently favored region for the mass of a Standard Model Higgs lied between and GeV.

As mentioned above the electroweak measurements indicated a preferred region between and GeV, making this a prime region where Higgs boson was finally discovered.

Actually, Higgs is not directly measured in the detectors because it decays into lighter Standard Model particles. Both experiments observe a new particle in the mass region around GeV.

The results were preliminary but the 5 sigma signal at around GeV seen was dramatic. This was indeed a new particle. The This particle was consistent with Higgs Boson. The particles ejected due to the collision are then studied. The Higgs boson was initially discovered as a new particle in , based on collisions in the LHC, and the new particle was subsequently confirmed to match the expected properties of a Higgs boson over the following years.

The idea of the Higgs boson was proposed for a rather strange reason. It was seen that if fundamental particles are treated to be massless, the equations become symmetric and appealing. This way, the equations could still be preserved. The idea seemed radical at first, and the scientific community took a very long time to accept the theory of the Higgs boson.

But how is the Higgs boson important? What are we to gain from further research on the subject? The answer is quite simple. The Higgs boson is one of the most important particles in the Standard Model. Further research on particle physics is bound to reveal further information on the fundamental nature of reality, and may even finally settle debates between string theorists, quantum gravity researchers and those who believe gravity to be an entropic force.

Arpan Dey, aged 15 years, is a high school student from India. He is interested in physical sciences and mathematics. He is also an aviation enthusiast. I am pursuing an UG course on Physics and I am amazed how a 15 year old published his journal on particle Physics.

Nice work Arpan. Keep it up. What a nice work. I am also interested in quantum mechanics and my age is 12 year only. So we can work together. Please give me your email if you have interest in my work. You can also email me on [email protected]. Your email address will not be published.

In some theories, neutrino mass also comes from an additional, brand new source that could hold the answers to other lingering particle physics mysteries. This new mechanism may also be related to how dark matter, which physicists think is made up of yet undiscovered particles, gets its mass.

Just over 40 years ago, a new theory about the early universe provided a way to tackle multiple cosmological conundrums at once. That coevolution continues today. Learn about the Standard Model of particle physics and how physicists use it to predict the subatomic future. Only a fraction of collision events that look like they produce a Higgs boson actually produce a Higgs boson.

Physicists see top quarks and Higgs bosons emanating from the same collisions in new results from the Large Hadron Collider. But every other second at the LHC, they do. The announcement on July 4 was just one part of the story. Take a peek behind the scenes of the discovery of the Higgs boson.
