The Standard Model of Particle Physics: A Triumph of Science
The Standard Model of particle physics is the most successful scientific theory of all time. It describes how everything in the universe is made of 12 different types of matter particles, interacting with three forces, all bound together by a rather special particle called the Higgs boson. It’s the pinnacle of 400 years of science and gives the correct answer to hundreds of thousands of experiments. In this explainer, Cambridge University physicist David Tong recreates the model, piece by piece, to provide some intuition for how the fundamental building blocks of our universe fit together. At the end of the video, he also points out what’s missing from the model and what work is left to do in order to complete the Theory of Everything.

If you were to take a coffee cup, and break it in half, then in half again, and keep carrying on, where would you end up? Could you keep on going forever? Or would you eventually find a set of indivisible building blocks out of which everything is made? Jonathan Butterworth explains the Standard Model theory and how it helps us understand the world we live in.

The standard model of particle physics is our fundamental description of the stuff in the universe. It doesn’t answer why anything exists, but does describe what exists and how it behaves, and that’s what we’ll be discovering in this video. We will cover the fermions, which contain the quarks and the leptons, as well as the bosons or force carriers. As well as which of the fundamental forces each of these fundamental particles interact with, along with the Higg...

The standard model of particle physics is our fundamental description of the stuff in the universe. It doesn’t answer why anything exists, but does describe what exists and how it behaves, and that’s what we’ll be discovering in this video. We will cover the fermions, which contain the quarks and the leptons, as well as the bosons or force carriers. As well as which of the fundamental forces each of these fundamental particles interact with, along with the Higgs field. We’ll also look at the conservation rules of particle physics, symmetries in physics and the various quantum numbers that rule which particle interactions are valid and which are not.

If we generalize the concept of bosons interacting with particles, we can get all fundamental particle physics. Complex math, but physicist Richard Feynman came up with a simple way to view these interactions - Feynman diagrams.
The 12 fermions are depicted as straight lines with arrows in the diagrams. The arrows represent the “flow” of fermions. No two arrows point towards each other. If time is in the x direction, then fermion arrows going forwards are matter particles, and those going backwards, antimatter particles.
All 6 quarks have color charges. All particles with color charges interact with the strong nuclear force. Quarks also have an electric charge, so they also feel the electromagnetic force.
Leptons can be divided into the electron and its heavier cousins, the muon and tau particles. These all have electric charges but no color charges. Neutrinos do not have a color charge or an electric charge, so they are not affected by the strong and electromagnetic forces.
All fermions carry something called weak isospin. This can be thought of as the “charge” of the weak force. It can be +1/2 or -1/2. All fermions interact with the weak force. But weak isospin can also be -1, 0, and +1 – the W- boson has a weak isospin of -1, W+ has +1, Higgs has -1/2, and Z boson and photons have a weak isospin of 0. Note that this zero is not the same has having no isospin. Everything in the standard model has a weak isospin except gluons.
The weak force has the power to turn one particle into another particle. It is the only force that can do that.
To recap, quarks interact with all forces, electron like particles interact with electromagnetism and the weak force, but do not interact with the strong force. Neutrinos only interact with the weak force and nothing else. Only quarks and gluons carry the strong force. Higgs bosons do not interact with photons or gluons. They confer mass to fundamental particles, so all fundamental particles with mass interact with Higgs.
The simplest force is electromagnetic which interacts with quarks and leptons. Repulsion is depicted in Møller scattering. Attraction is shown in Bhabha scattering. When electrons and positrons are near each other, they can annihilate or attract each other.'
Weak force is felt by all of the standard model particles, except gluons. W-boson can do something very special. They can change the identity or flavor of the particle - a neutron to a proton. We probably would not exist without it.
Z-boson has no electric charge and can mediate interactions with electrically neutral particles like the neutrino and the Higgs.
The strong force is the most complicated mathematically, but since it only relates to quarks and gluons. A pair of quarks can change color. This happens all the time inside protons and neutrons, and is the glue that binds the quarks together.
Because gluons themselves contain color charges, they also interact with each other via complicated diagrams. This is what flux tubes are made of. These tubes are formed when you try to pull quarks apart.
Mesons are formed when a quark tries to leave a nucleon. These mesons are a combination of a quark, anti-quark pairs which mediate the strong force between protons and neutrons.
Pi mesons exchanges colors and quarks between protons and neutron. This is what keeps them glued together. Color charges must be conserved. Either red, blue, and green must combine, or color anti-color must combine to form a neutral color charge.
The most prominent process used at the Large hadron collider to make a Higgs boson is called the gluon fusion process. During high energy proton-proton collisions, two high energy gluons can be produced. Strong force interaction can turn these into top quarks which fuse together via a loop of top quark, anti-top quark creation and annihilation. The energy of this can create a Higgs boson.

If we generalize the concept of bosons interacting with particles, we can get all fundamental particle physics. Complex math, but physicist Richard Feynman came up with a simple way to view these interactions - Feynman diagrams.
The 12 fermions are depicted as straight lines with arrows in the diagrams. The arrows represent the “flow” of fermions. No two arrows point towards each other. If time is in the x direction, then fermion arrows going forwards are matter particles, and those going backwards, antimatter particles.
All 6 quarks have color charges. All particles with color charges interact with the strong nuclear force. Quarks also have an electric charge, so they also feel the electromagnetic force.
Leptons can be divided into the electron and its heavier cousins, the muon and tau particles. These all have electric charges but no color charges. Neutrinos do not have a color charge or an electric charge, so they are not affected by the strong and electromagnetic forces.
All fermions carry something called weak isospin. This can be thought of as the “charge” of the weak force. It can be +1/2 or -1/2. All fermions interact with the weak force. But weak isospin can also be -1, 0, and +1 – the W- boson has a weak isospin of -1, W+ has +1, Higgs has -1/2, and Z boson and photons have a weak isospin of 0. Note that this zero is not the same has having no isospin. Everything in the standard model has a weak isospin except gluons.
The weak force has the power to turn one particle into another particle. It is the only force that can do that.
To recap, quarks interact with all forces, electron like particles interact with electromagnetism and the weak force, but do not interact with the strong force. Neutrinos only interact with the weak force and nothing else. Only quarks and gluons carry the strong force. Higgs bosons do not interact with photons or gluons. They confer mass to fundamental particles, so all fundamental particles with mass interact with Higgs.

What is the Large Hadron Collider used for? How do we know that dark matter exists? Join Pauline Gagnon as she explores these questions and the current ongoing research at CERN, the European Laboratory for Particle Physics. Watch the Q&A here: https://youtu.be/vQ8W6_uM0Pw
Pauline's new book 'Who cares about particle physics?: Making sense of the Higgs Boson, the Large Hadron Collider and CERN' is available now: https://geni.us/duwOL
Subscribe for regular science videos: http://bit.ly/RiSubscRibe
Could we be at the dawn of a huge revolution in our conception of the material world that surrounds us?
The creativity, diversity and motivation of thousands of scientists have gone into CERN, and ensured the success of one of the largest scientific projects ever undertaken. It has led to scientists being able to describe the smallest constituents of matter, and the role of the Higgs boson. This talk explores the world of particle physics, spanning the infinitesimally small to the infinitely large.
This talk was recorded at the Ri on 26 September 2022.
Pauline Gagnon first studied at San Francisco State University then completed a PhD in particle physics at University of California in Santa Cruz. Pauline then started research activities at CERN, the European Laboratory for Particle Physics located near Geneva, where Pauline worked as a Senior Research Scientist with Indiana University until retirement in 2016.
