What is the quark makeupof.K¯0

Short Answer

Expert verified

The kaonsK¯0 is made from.sd¯+s¯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¯0 is neutrally charged antiparticle has the same mass and it contains a strange quark and a down antiquark.

The charge of K¯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¯ and s¯d.

Strangeness of sd¯ is (−1)+0=−1.

Strangeness ofs¯d is.(+1)+0=+1

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

(τ+,restenergy=1777MeV)A positive tau(τ+,restenergy=1777MeV)is moving with kinetic energy in a circular path perpendicular to a uniform 1.20T magnetic field.

(a) Calculate the momentum of the tau in kilogram meters per second. Relativistic effects must be considered.

(b) Find the radius of the circular path.

(a) A stationary particle 1 decays into particles 2 and 3, which move off with equal but oppositely directed momenta. Show that the kinetic energy K2 of particle 2 is given by

K2=12E2[E1-E22-E32]

Where, E1,E2,and E3are the rest energies of the particles.

(b) A stationary positive point π+(rest energy 139.6 MeV) can decay to an antimuon μ+(rest energy 105.7 MeV) and a neutrino

ν(rest energy approximately 0). What is the resulting kinetic energy of the antimuon?

The quark makeups of the proton and neutron are uudand,uddrespectively. What are the quark makeups of (a) the antiproton and (b) the antineutron?

Question: What is the quark formation that makes up (a) the xi-minus particle and (b) the anti-xi-minus particle? The particles have no charm, bottom, or top.

Question: Due to the presence everywhere of the cosmic background radiation, the minimum possible temperature of a gas in interstellar or intergalactic space is not 0 K but 2.7 K. This implies that a significant fraction of the molecules in space that can be in a low-level excited state may, in fact, be so. Subsequent de-excitation would lead to the emission of radiation that could be detected. Consider a (hypothetical) molecule with just one possible excited state. (a) What would the excitation energy have to be for 25% of the molecules to be in the excited state? (Hint: See Eq. 40-29.) (b) What would be the wavelength of the photon emitted in a transition back to the ground state?
