# What is the quark makeup of.${\overline{\mathbf{K}}}^{{\mathbf{0}}}$

The kaons${\overline{K}}^{0}$ is made from.$s\overline{d}+\overline{s}d=0$

See the step by step solution

## Step 1: Definition of kaon.

A kaon is also named as $K$mesons. It is a group of your mesons divided by a quantum number called strangeness.

In the quark model there are bound states of a strange quark and an up or down antiquark.

## Step 2: The quark makeup of.K¯0

The given kaons${\overline{K}}^{0}$ is neutrally charged antiparticle has the same mass and it contains a strange quark and a down antiquark.

The charge of ${\overline{K}}^{0}$is.$Q=0$

To make the overall charge zero, we need to take one quark and other an anti quark.

The possible quark is $s\overline{d}$ and $\overline{s}d$.

Strangeness of $s\overline{d}$ is $\left(-1\right)+0=-1$.

Strangeness of$\overline{s}d$ is.$\left(+1\right)+0=+1$

Hence the kaons ${\overline{K}}^{0}$are made from.$s\overline{d}+\overline{s}d=0$
