Yes, It will emit energy (virtual/real photons) and further can give matter and anti-matter again (say, quarks and anti quarks) which further can give rise to several other final state particles

You need to ask the right question. Your current question is meaningless.

The total mass energy is conserved, so for the example of an electron colliding with a positron, they emit gamma ray photons. For more massive particles, a cascade of hadrons can be created.

The collision between matter and antimatter can lead to the annihilation of both, in the same way the collision between particles and antiparticles does, thus giving rise to high-energy photons (gamma rays) or other particle–antiparticle pairs. The end result of matter meeting antimatter is a release of energy proportional to the mass as the mass-energy equivalence equation, E=mc2 shows.

Could you please be specific and add: "How the particles and antiparticles collide".

The difference range from creation of other particles, gamma radiation

or be..... a future of human space travel.....

Particles and antiparticles collide in high energy accelerators.

During 90s, at the Large electron positron collider at CERN

collided electron positron pairs at the mass of the Z-boson.

They could create a Z bosons, and their existence was

confirmed there. If the collision energy is less than the

Z mass then this collision cannot create a real Z boson.

Then Z boson will be created virtually. In spite of that

low mass particles can be created after balancing all the

required quantum numbers.

"What happens when matter and anti matter collide? " - NOBODY knows nowadays! If somebody had known this, he would be able, as God, to explain the whole Nature and the related Physics phenomena... And the Physics goes ahead to know that, step by step, very slowly, yet it paves a true way, even though not always from the first time having chosen a true road!

All the best!
