How were the Higgs bosons produced?

How were the Higgs bosons produced?

When two protons collide within the LHC, it is their constituent quarks and gluons that interact with one another. These high-energy interactions can, through well-predicted quantum effects, produce a Higgs boson, which would immediately transform – or “decay” – into lighter particles that ATLAS and CMS could observe.

What happens when two Higgs bosons collide?

This collision is consistent with the production of two Higgs particles, with one Higgs boson decaying to two bottom quark jets (red) and the other Higgs boson decaying to two photons (green).

Can a Higgs boson be produced in a head on collision?

But not just any collision can create a Higgs boson. “The Higgs is not just created from a ‘poof’ of energy,” says Laura Dodd, a researcher at the University of Wisconsin, Madison. “Particles follow a strict set of laws that dictate how they can form, decay and interact.”

How do you detect Higgs boson?

Because the Higgs boson decays very quickly, particle detectors cannot detect it directly. Instead the detectors register all the decay products (the decay signature) and from the data the decay process is reconstructed.

Do bosons interact with the Higgs field?

The Higgs particle, like many other elementary particles, is not a stable particle. (The Higgs particle does not interact with massless particles, such as a photon or a gluon. Since these particles don’t interact with the Higgs field, the Higgs boson also doesn’t interact with them.)

How many collision occur before we see 1 Higgs boson?

Scientists collide particles at these energies to produce other particles, including a Higgs boson, using Einstein’s famous relation E=mc2. At the Tevatron or LHC, only about one collision per trillion will produce a Higgs boson.

What is the Higgs boson?

The Higgs boson is the visible manifestation of the Higgs field, rather like a wave at the surface of the sea. Candidate Higgs boson events from collisions between protons in the LHC.

What is the Higgs field and how does it work?

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.

What is the total decay width of a Higgs boson?

Notes Note that such events also occur due to other processes. In the Standard Model, the total decay width of a Higgs boson with a mass of 125 GeV/c 2 is predicted to be 4.07×10 −3 GeV. It is quite common for a law of physics to hold true only if certain assumptions held true or only under certain conditions.

Does the Higgs boson have a quartic potential?

The anatomy of double Higgs boson production In the SM, the Higgs field potential is postulated to be a quartic potential (the lowest possible level for constructing a gauge-invariant Lagrangian). After EWSB, this results in a trilinear and a quadrilinear self-interaction to the Higgs boson in the low energy regime.
