Strange and non strange current

In summary, strange current is a type of electrical current that contains strange quarks, which have a high mass and short lifetime. It has unique properties and behaviors that have been studied in particle physics experiments and proposed as a potential source of clean energy. Non strange current, on the other hand, does not contain strange quarks and is commonly found in electric currents in wires and circuits. The main differences between the two include the presence of strange quarks, unique properties, and the ability for strange current to decay into non strange current. Strange current can be produced through high-energy collisions of particles or naturally in certain cosmic rays or neutron stars.

Can anyone explain the meaning of strange and non strange current.i'm confused about the definition

I guess you are referring to the quark coor currents

[tex]j^a_f = \sum_{ik}\bar{\psi}^i_f \gamma^\mu (T^a)_{ik}\psi^k_f[/tex]

You get such a color current (where ik and a are the SU(3) color indices) for each flavour f. For the total color current you have to sum over all flavors f=1..6. Is it this what you mean?
 

What is strange current?

Strange current is a type of electrical current that is characterized by the presence of strange quarks. These quarks have a high mass and short lifetime, and their presence in the current leads to unique properties and behaviors.

What is non strange current?

Non strange current, on the other hand, is any electrical current that does not contain strange quarks. This includes most common types of current, such as electric currents in wires and circuits.

What are the applications of strange current?

Strange current has been studied in particle physics experiments, and its properties have been used to better understand the fundamental building blocks of matter. Additionally, strange current has been proposed as a potential source of clean and efficient energy in fusion reactors.

How is strange current produced?

Strange current can be produced through high-energy collisions of particles, such as in particle accelerators. It can also be produced naturally in certain types of cosmic rays or in the cores of neutron stars.

What are the differences between strange and non strange current?

The main difference between strange and non strange current is the presence of strange quarks. Strange current has unique properties, such as longer range and stronger interactions, compared to non strange current. Additionally, strange current can decay into non strange current through the weak nuclear force.
