5 giorni fa · In theoretical physics, quantum field theory (QFT) is a theoretical framework that combines classical field theory, special relativity, and quantum mechanics.: xi QFT is used in particle physics to construct physical models of subatomic particles and in condensed matter physics to construct models of quasiparticles.
4 mag 2024 · The Standard Model hypothesises a field called the Higgs field (symbol: ϕ), which has the unusual property of a non-zero amplitude in its ground state (zero-point) energy after renormalization; i.e., a non-zero vacuum expectation value.
2 giorni fa · Historical background See also: History of quantum field theory, History of subatomic physics, Julian Schwinger, and John Clive Ward In 1954, Yang Chen-Ning and Robert Mills extended the concept of gauge theory for abelian groups, e.g. quantum electrodynamics, to nonabelian groups to provide an explanation for strong interactions. In 1957, Chien-Shiung Wu demonstrated parity was not conserved ...
20 apr 2024 · Higgs boson, particle that is the carrier particle, or boson, of the Higgs field, a field that permeates space and endows all elementary subatomic particles with mass through its interactions with them.

I am trying to understand the mass acquisition of particles in the Standard Model based on the book ' Fundamentals of Neutrino Physics and Astrophysics ' by C. Giunti, and several doubts have arisen regarding the Higgs Mechanism.
26 apr 2024 · 26 April 2024 | By. ATLAS Collaboration. The discovery of the Higgs boson by the ATLAS and CMS collaborations in 2012 was crucial for unravelling the mysteries of the Higgs field and its potential. Understanding the shape of the Higgs potential provides crucial information about the long-term stability of the Universe.
19 apr 2024 · In 1966, he was first to predict that this “Higgs field” must also come with a “Higgs particle”. If discovered, it would prove that the Standard Model was a consistent theory of nature.
