What is the quark makeupof.K炉0

Short Answer

Expert verified

The kaonsK炉0 is made from.sd炉+s炉d=0

Step by step solution

01

Definition of kaon. 

A kaon is also named as Kmesons. 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.

02

The quark makeup of.K¯0 

The given kaonsK炉0 is neutrally charged antiparticle has the same mass and it contains a strange quark and a down antiquark.

The charge of K炉0is.Q=0

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

The possible quark is sd炉 and s炉d.

Strangeness of sd炉 is (鈭�1)+0=鈭�1.

Strangeness ofs炉d is.(+1)+0=+1

Hence the kaons K炉0are made from.sd炉+s炉d=0

Show that if, instead of plotting strangenessS versus chargeq for the spin -12baryons in Fig. 44-3a and the spin-zero mesons in Fig.44-3b , we plot the quantity Y=B+Sversus the quantity Tz=q-12(B+S), we get the hexagonal patterns without using sloping axes. (The quantityY is called hypercharge, andTzis related to a quantity called isospin.)

There is no known meson with charge quantum number q=+1and strangeness S=-1or with q=-1and .S=+1Explain why in terms of the quark model.

A proton has enough mass energy to decay into a shower made

up of electrons, neutrinos, and their antiparticles. Which of the following

conservation laws would necessarily be violated if it did: electron lepton number or baryon number?

From tables 44-3 and 44-5, determine the identity of the baryon formed from quarks (a),ddu(b),uusand (c)ssd.Check your answers against the baryon octet shown in Fig 44-3a.
