Paul Dirac predicted the existence of antimatter with his relativistic wave equation in 1928.
If matter and antimatter collide, they annihilate each other.
He saw how magnetic traps could make antimatter useful in medicine, principally in tumor treatment.
There is both matter (such as electrons) and oppositely charged antimatter (such as positrons).
What is CP violation and how does it explain the fact that matter outnumbers antimatter in the universe?
The definition of matter and antimatter is purely conventional.
This brief survey of recent Lorentz tests only lists those experiments involving light, ordinary matter, and antimatter .
What everyone actually needs here is a more efficient mobile power source, whether it be cold fusion, lithium air or a matter / antimatter reactor.
Those equations and present particle physics say that matter and antimatter are equivalent.
The answer to your question is, thus, clearly yes: matter would be created when antimatter particles collide at high energy.
