With the recommendation of the P5 panel for “an aggressive R&D program that, while technologically challenging, could yield revolutionary accelerator designs that chart a realistic path to a 10 TeV pCM collider” multiple future collider options are discussed within the HEP community. Several (less discussed) options, such as same sign lepton or photon colliders, are currently being explored in Berkeley across multiple divisions. In this talk I will present recent results for a wakefield electron-positron and electron-electron collider. For both the strong electric and magnetic fields produced by the tightly focused beams lead to changes in the beam shape, the emission of hard photons and electron-positron pair creation. We take these beam-induced secondary photon, electron and positron beams into account when comparing the new physics reach of each collider option. In fact, the secondary beams can be the leading contribution to the production of new physics states as I will demonstrate for the example of heavy charged fermions decaying to various final states.
