The goal of this paper it to prove existence theorems for one parameter families (branches) of ejection-collision orbits in the planar circular restricted three body problem (CRTBP), and to study some of their bifurcations. The orbits considered are ejected from one primary body and collide with the other (as opposed to more local ejections-collision orbits which involve only a single body). We consider branches which are (i) parameterized by the Jacobi integral (energy like quantity conserved by the CRTBP) and (ii) parameterized by the two body mass ratio when energy is fixed. The method of proof is constructive and computer assisted, hence can be applied in non perturbative settings and (potentially) to other conservative systems of differential equations. The main requirement is that the system should admit a change of coordinates which regularizes the singularities (collisions). In the planar CRTBP the necessary regularization is provided by the classical Levi-Civita transformation.
