Weak neutral current Moslim Sohani Intermediate bosons Weak charged currents Structure of neutral current Conclusion

Intermediate bosons 1 Charged Intermediate Bosons are essential 

Intermediate bosons 1 Neutral Intermediate Boson has to be included  What’s the Structure of Weak Neutral Current?

Weak charged currents 1 Matter-Antimatter scattering is weaker than Matter-Matter or Antimatter-Antimatter

Weak charged currents 2

Weak charged currents 3

Weak charged currents 4

Attention Weak Charged Currents interact with Left handed particles and Right handed antiparticles.

Structure of neutral current 1 Same situation for Quarks shows that back scattering from opposite helicity Quark is forbidden

Structure of neutral current 2 Neutral Current might interact with Right handed particles as well as Left handed particles

Structure of neutral current 3

Structure of neutral current 4 Measurements proof the interaction of Neutral current with Right handed particles.

Conclusion Weak Charged Currents mediate interactions with right handed particles and left handed antiparticles. Weak Neutral Current mediates interaction with both right and left handed particles and their antiparticles. Out look Electromagnetic interaction has the same structure as Weak Neutral Current and one can realize the unification of these two interactions. Assuming that the Z boson in Weak Interaction and  in Electromagnetic interaction belong to the same family of intermediate bosons:  starting point to construct Electro-Weak Interaction Model.
