Polarization observables for millicharged particles in photon collisions

Understand

Particles in a hidden sector can potentially acquire a small electric charge through their interaction with the Standard Model and can consequently be observed as millicharged particles.

• We systematically compute the production of millicharged scalar, fermion and vector boson particles in collisions of polarized photons.
• The presented calculation is model independent and is based purely on the assumptions of electromagnetic gauge invariance and unitarity.
• Polarization observables are evaluated and analyzed for each spin case.
