Feynman diagaram of Kaon decay

In summary, a Feynman diagram is a visual representation of the interactions between particles in a physical process. Specifically, in the case of Kaon decay, it shows the exchange of particles and resulting decay of a Kaon into other particles. This process involves a strange quark transforming into an up quark, emitting a W boson, which then decays into an electron and electron antineutrino, while the up quark becomes a down quark, forming a pion. The direction of the arrows in the diagram indicate the flow of momentum, with particles moving forward in time and antiparticles moving backwards. The Feynman diagram of Kaon decay is important in understanding particle physics because it allows scientists to visualize and understand

Homework Statement


I am asked to draw a feynman diagram of [itex]K^- \rightarrow \mu \nu [/itex]

Homework Equations


[itex]K^-[/itex] consist of [itex]s\bar{u}[/itex]

The Attempt at a Solution


I wonder what the direcion of the arrows should be, my guess is something like the attached image.
edit: Ah, where the left u shoudl be an s and the right u should be an antiup. (attached the wrong pic)

That decay can't happen, can it? Doesn't it violate lepton number conservation?
 

Related to Feynman diagaram of Kaon decay

1. What is a Feynman diagram of Kaon decay?

A Feynman diagram is a visual representation of the interactions between particles in a physical process. In the case of Kaon decay, it shows the exchange of particles and the resulting decay of a Kaon into other particles.

2. How does a Kaon decay according to the Feynman diagram?

In a Kaon decay, a strange quark within the Kaon transforms into an up quark, emitting a W boson. The W boson then decays into an electron and an electron antineutrino, while the up quark becomes a down quark, forming a pion.

3. What does the direction of the arrows in the Feynman diagram represent?

The direction of the arrows in a Feynman diagram indicates the direction of the flow of momentum, with particles moving forward in time and antiparticles moving backward in time.

4. How does the Feynman diagram of Kaon decay relate to the Standard Model of particle physics?

The Feynman diagram of Kaon decay is a visual representation of a process that is described by the Standard Model, which is a theoretical framework that explains the behavior of particles and their interactions.

5. Why is the Feynman diagram of Kaon decay important in understanding particle physics?

The Feynman diagram of Kaon decay allows scientists to visualize and understand the interactions between particles and the fundamental forces at play. It also provides a way to calculate the probability of different outcomes in a physical process, which is crucial for predicting and verifying experimental results in particle physics.
