Higgs mechanism

n.
The hypothetical mechanism in quantum mechanics by which certain particles interact with the Higgs field and thereby have the property of mass.

[After Peter Ware Higgs (born 1929), British physicist.]

Reaching energies of 100 TeV and beyond would allow precise studies of how a Higgs particle interacts with another Higgs particle, and thorough exploration of the role of the electroweak symmetry breaking in the history of our universe.
The seesaw mechanism [8-12] is automatically implemented in the model after the electroweak symmetry breaking. Due to the [Z.sub.2] symmetry, only two right-handed neutrinos [N.sup.1,2.sub.R] are relevant to the seesaw mechanism.
"The Higgs boson plays a crucial role in our world - it provides mass to the Z and to the related W particles through a mechanism known as electroweak symmetry breaking.
It provides needed credibility for string theory and an elegant pathway for explaining electroweak symmetry breaking and the high energy interactions among weak, strong, and electromagnetic forces, all important to the 'Theory of Everything' advanced by Stephen Hawking.
That is, here is a mechanical analogue of spontaneous electroweak symmetry breaking in the SM.
"We've closed it down now to upgrade beam energy to 6.5 teraelectronvolts per nucleon that will help us explore the masses of elementary particles generated by the Higgs mechanism via electroweak symmetry breaking."
That job, in physics speak, is "electroweak symmetry breaking." In the universe's earliest picoseconds, electromagnetism was a component of a more primordial "electroweak" force, incorporating what's now called the weak force (known for its role in radioactivity).
The SMEFT Lagrangian (see (2)) containing the Wilson coefficients in the SILH bases of dimension-6 CP-conserving operators can be defined in terms of the mass eigenstates after electroweak symmetry breaking (Higgs boson, W, Z, photon, etc.) as follows:
