The ghost of my stories would be explainable by quantum and regular physics. After reflexion about my ghosts, I decided to put it like this :
They are composed of higgs boson and fermions that are forced into a shape by a magnetic or electromagnetic field.The pair of particles is able to turn into their condensate version at will by the ghost but with straining effort. It would explain why they can only appear and interact in the physical world for short periods at a time.
However, I know that higgs bosons decay into other particles almost immediately after their creation and I don't know to explain their longer shelf-life in their pairing with fermions. I want to give a explanation that seem « authentic », well-developed in both scientific and layman terms. Or, could this be already more concise to explain in scientific terms only ?
