The 3 body problem and bosons are two separate concepts in physics that are not directly related to each other. The 3 body problem refers to the mathematical challenge of predicting the motions of three interacting bodies in space, while bosons are a type of elementary particle that can carry forces between other particles.
In regards to the question of whether a force carrier with a large mass could turn a two body particle system into a three body system, it is important to understand that the mass of a force carrier is not the only determining factor in the behavior of particles. The interactions between particles are also influenced by other fundamental forces, such as electromagnetism and the strong and weak nuclear forces.
Therefore, it is unlikely that increasing the mass of a force carrier would automatically result in a three body system. Additionally, the concept of a force carrier having a large mass is not consistent with our current understanding of particle physics. Force carriers are typically massless or have very small masses, and their role is to mediate interactions between particles rather than directly affecting their masses.
In conclusion, the 3 body problem and bosons are both fascinating topics in physics, but they should not be conflated. While a force carrier with a large mass could potentially have an impact on the behavior of particles, it is not a direct determinant of whether a two body system becomes a three body system.
