Our universe seems pretty complicated. We have a weird zoo of elementary particles, which interact through very different fundamental forces.

#ElectroweakTheory
In this video we will take a look at the electroweak theory, which unites the weak and electromagnetic force. This theory shows us how these two fundamental forces are linked, and how they unite at high energies forming the electroweak force. In the video about the weak force, we discussed how we couldn't just write down the Lagrangian for the weak force in the same way as we did with the electromagnetic force. The reason is that we are not allowed to have massive gauge bosons or in other words the force carriers must be massless. This is fine in QED in part because t...

The Electroweak interaction: The unification of the electromagnetic and the weak interactions
In this video, we explain in a very didactic and entertaining way, the electroweak interaction. This interaction is the unification of the electromagnetic interaction with the weak interaction. In the early universe, both interactions were a single one; separating then when the universe became colder. While the carriers of the electromagnetic interaction are the massless photons, the carriers of the weak interaction are the bosons Z and W which are very heavy. Both set of carriers appear naturally from the electroweak theory, where the bosons Z and W get massive via Higgs mechanism. At very high temperatures (10^16 Kelvin approximately), the bosons Z and W become massless, making then the weak interaction an infinite range one in such regimes. Then we can perceive the separation between th...

What is the Electroweak force? Electroweak theory explained: At the moment of the Big Bang, all 4 fundamental forces were probably the same. But as temperatures and energies lowered, the forces separated into distinct interactions of their own.
The energies at which electromagnetism and the weak force unite s something we can simulate in particle accelerators such as the Large Hadron collider in Geneva. But these two forces appear to be very different, so how do they unite?.
Gauge bosons - like photons mediate the electromagnetic force, and the W and Z bosons mediate the weak nuclear force. The exchange of the virtual versions of these particles confer the appropriate force. So for example, when two electrons are near each other, their repulsion is due to the exchange of virtual photons.
The weak nuclear force also works via the exchange of a virtual W or Z boson. In the beta decay of a neutron, one of its down quarks turns into a up quark by emitting a W- boson. This turns the Neutron into a proton. This W- boson almost immediately decays into an electron and an anti-neutrino. So what we detect in this decay is the electron and the antineutrino. The virtual particle is not detectable. The weak force is unique in this respect in that it is the only force which can change the identity of an elementary particle.
One big problem in uniting the electromagnetic force with the weak force is the fact that photons are massless, but the W and Z bosons are very massive – their masses are about 80 and 90 Giga electron volts or GeV. This is over 80 times the mass of a proton.
American Physicist Sheldon Glashow had noticed that even though electromagnetism is millions of times stronger than the weak force at large scales, the strengths of both forces appeared to be identical at very small lengths – about 1/1000th the width of a proton, suggesting a point where the two forces may merge as one.
Glashow showed that an acceptable theory for the unification of the weak and electromagnetic interactions could be found where the two forces are treated together as one – as an electroweak force. And his model predicted 4 bosons that would mediate this force. These bosons were called W1, W2, W3, and B.
There were two problems with his model. First it predicted a third weak force neutral Boson, now called the Z boson, which was not predicted by any theory at that time. The other was that Glashow’s model only worked if all 4 Bosons were massless. One can call this masslessness, a kind of symmetry.
But this did not fit observations. Something had to break this symmetry because the weak force was weak and interacted only at very small distances, indicating that its mediating bosons had to be massive. Glashow could not find the right mechanism for making the 4 massless bosons from his electroweak theory into the 3 heavy weak force bosons and the massless photon.
Three years later in 1964, Robert Brout and Francois Englert in Brussels and Peter Higgs developed a mechanism whereby mass could be given to elementary particles while maintaining a meaningful theory. The Brout-Englert-Higgs (BEH) mechanism employed the properties of a field (what is now called the Higgs field) to break the symmetry, and it predicted another massive particle, the Higgs boson.
In 1967 and 1968, Pakistani physicist Abdus Salam and American physicist Steven Weinberg took the ideas of the Higgs mechanism, and combined them with Glashow’s ideas to show how Glashow’s 3 weak force mediating particles could gain mass, while the photon of electromagnetism could remain massless, in the same theoretical framework. This is the basis of what is now electro-weak theory.
#electroweakforce
So now the question is, how does the Higgs mechanism give rise to masses in the 3 weak force particles, but not the photon. At energy scales above 160 GeV, the Higgs potential looks like a normal field potential, and does not confer mass. But at energies below about 160 GeV, the Higgs potential looks like a sombrero. That's why this is called the "Mexican hat."
The way the three Glashow particle interact with the Higgs potential determines the masses of the gauge bosons that we observe for the weak force (W+, W-, Z bosons), and for electromagnetism (photons). All 4 particles emerge from the same underlying principle.

#ElectroweakTheory
In this video we will take a look at the electroweak theory, which unites the weak and electromagnetic force. This theory shows us how these two fundamental forces are linked, and how they unite at high energies forming the electroweak force. In the video about the weak force, we discussed how we couldn't just write down the Lagrangian for the weak force in the same way as we did with the electromagnetic force. The reason is that we are not allowed to have massive gauge bosons or in other words the force carriers must be massless. This is fine in QED in part because the photon is massless, but this doesn't work for the weak force as W^-, W^+ and Z bosons are all very massive. The answer to how these particles are allowed to be massive is explained by the Higgs mechanism, which is an essential part of electroweak theory. Because these two forces only unite at energies above our everyday life, we don't experience this unification. But we can recreate the high energy conditions at the LHC at CERN.
To understand the essence of the issue we must understand that the standard model is based on gauge theories with certain symmetries that the theory must obey. The symmetry group of the standard model is a rather complicated topic that deserves a video on its own. But the essence is that when we write the Lagrangian of the standard model, such that it obeys the underlying symmetries, then we are not allowed to write any mass term for our gauge bosons, thus all force carriers of the standard model must be massless. If we wrote mass terms, we would break the symmetry of the standard, which means we break gauge invariance, and this just means that the standard model would be useless. The trick is, that we can write standard model Lagrangian such that it abides to the necessary symmetries, but we can write it such that it has a symmetry breaking mechanism! Thus, the Lagrangian abides to the necessary symmetry, but it has a mechanism to then break this symmetry and this symmetry breaking is what generates the masses of the weak force bosons! The mechanism is called the Higgs mechanism.

In this video, we explain in a very didactic and entertaining way, the electroweak interaction. This interaction is the unification of the electromagnetic interaction with the weak interaction. In the early universe, both interactions were a single one; separating then when the universe became colder. While the carriers of the electromagnetic interaction are the massless photons, the carriers of the weak interaction are the bosons Z and W which are very heavy. Both set of carriers appear naturally from the electroweak theory, where the bosons Z and W get massive via Higgs mechanism. At very high temperatures (10^16 Kelvin approximately), the bosons Z and W become massless, making then the weak interaction an infinite range one in such regimes. Then we can perceive the separation between the weak and the electromagnetic interaction as a phase transition. Interestingly, although the Higgs mechanism gives mass to the appropriate particles, still is not able to give mass to the neutrinos. However, it is experimentally known that the neutrinos are massive. This problem of the neutrino mass will be discussed in future videos.
