A collision between any particle and its anti-particle partner leads to their mutual annihilation, giving rise to various proportions of intense photons (gamma rays), neutrinos, and sometimes less-massive particleantiparticle pairs.
The interaction between particles and their antiparticles leads to their annihilation, resulting in the production of various forms of radiation, including gamma rays, neutrinos, and sometimes less massive particle-antiparticle pairs.
