What is wrong with the standard model?
The standard model predicts the wrong vacuum energy (much higher than the observed value, even including the cosmological constant) The top mass and the Higgs mass could potentially make the standard model unstable / unrenormalizable / wrong
What is needed to complete the standard model?
Since the pre-standard model theory was complete with only three quarks, the name made some sense. The full standard model today needs six quarks. That hasn't made the word any less fun to say.
What is the standard model all about?
The Standard Model of Particle Physics is scientists’ current best theory to describe the most basic building blocks of the universe. It explains how particles called quarks (which make up protons and neutrons) and leptons (which include electrons) make up all known matter. It also explains how force carrying particles, which belong to a broader group of bosons, influence the quarks and leptons.
Can we understand the standard model?
The Standard Model is the name given in the 1970s to a theory of fundamental particles and how they interact. It incorporated all that was known about subatomic particles at the time and predicted the existence of additional particles as well. There are seventeen named particles in the Standard Model, organized into the chart shown below.

Particle Families
Fundamental particles are either the building blocks of matter, called fermions, or the mediators of interactions, called bosons. There are twelve named fermions and five named bosons in the standard model. Fermions obey a statistical rule described by Enrico Fermi (1901–1954) of Italy, Paul Dirac (1902–1984) of England, and Wolfgang Pauli (1900–19
Particle Interactions
Three of the four fundamental fources of nature are included in the standard model of particle physics — electromagnetism, the strong force, and the weak force. (Gravity is not included in the standard model.) Each force acts between particles because of some property of that particle — charge for electromagnetism, color for the strong force, and f
Mass and Gravity
All fermions are thought to have a nonzero mass. Particles in generation I are less massive than those in generation II, which are less massive than those in generation III. Within the generations, quarks are more massive than leptons and neutrinos are less massive than the other leptons. Bosons are divided when it comes to mass. Gluons and photons
Group Theory
For those who like fancy math, the standard model is described using group theory notation as… SU(3) × SU(2) × U(1) where the gauge group of strong interactions is… SU(3) and the gauge group of electroweak interactions is… SU(2) × U(1) Notes… 1. SU(3) 1.1. 3rd order special unitary group 1.2. the set of all 3 × 3 unitary matrices with unit determin
Lagrangian
What is this? The standard model Lagrangian. What does it say? I'll let you know when I figure it out. ℒ = −¼FμνFμν + iψ̄D̸ψ + h.c. + ψiyijψjφ + h.c. + Dμφ2 − V(φ) See full list on physics.info
