Many books in Modern physics have used mathematical descriptions on special particles to justify spin of particles.It is very important in theoretical physics to find a feasible solution for this problem that holds for all interactions in particle physics.All comments and answers will be acknowledged.Thank you so much for your nice discussions.If you know any reference or paper , please introduce us.We appreciate your kindly efforts.

Article Adaptive Review of Three Fundamental Questions in Physics
In "The Magnetic Interaction," we investigated the magnetic force in general, the shape of magnetic field produced by charged particles, how charged particles interacted with magnetic fields, why electrons & protons gyrate oppositely, the force they produced with magnetic fields, the Spinning Magnetic Field (SMF) produced by charged particles, is suggested to produce magnetic fields on both poles of the particles, these forms a base for atomic model and a mechanism producing spectral line; (at: http://www.journaloftheoretics.com/links/Papers/MY.pdf).
Then we deeply investigated and suggested the strong force in "THE SPINNING MAGNETIC FORCE" (at: http://www.journaloftheoretics.com/links/papers/my-s.pdf), it explain many phenomena, and represent one of the missing links in theoretical physics.
Hello and good day.In the following link , we can investigate spin of two Fermions :

In this link , we will see the application of mathematical operators to justify the spin phenomenon.

In this case , We have application of permutations to explain spin of particles :

Quantum transport group in Poland have other ideas to explain spin while interacting clusters.

I think looking to this problem has been investigated merely through mathematical aspects by operators in quantum mechanics and permutations in Algebra and combinations.I am searching for a physical justification for changing spin of particles after providing a new particle by interactions.So , the new particle has spin or non linear velocity.The problem of spin about particles is very important during physicists and so far I have not seen any practical approach to justify spin of particles from Gravitons to new format of particles based on defined force between then as defined above.
How can we interpret this change of spin among defined particles in physics ?
All comments and ideas are accepted and will be acknowledged.

An other mathematical insight to the spin is through Pauli matrices that play an important role In Dirac Sea and its equations.You can review its general idea in the below link :

Prof Xavier Oudet in France has written a paper in 1995.I have requested it.He defines spin from electron.I need definition of spin from graviton.

Sounds like Dirac Zitterbewegung.
See Section 1 of www.tachyonmodel.com, especially 1.16, where this question is covered.
It should also be added that an electron cannot change into a positron in, say, a hydrogen atom. If it did, the zitterbewgung model would require twice the mass energy of the electron in the exchange, which would eject it from the atom. Not only that, but a positron would be repelled by the nucleus. If all of this were the case, hydrogen would be unstable, and this would have been observed. Furthermore, unstable hydrogen would have prevented the development of life as we know it.
This question on researchgate propose my question in another way.
Please follow this question and upvote their nice comments.
Thank you so much.
