Abstract
Standard radiation zeros arise from the factorization properties of tree-level amplitudes involving a massless photon and can occur when all charged particles in the initial and final state have the same sign. We investigate how several different processes involving new scalar particles beyond the standard model may exhibit radiation zeros and how this structure might be exploited to probe their electromagnetic structure. We focus on (i) unnoticed aspects of angular zeros in the process e −+ e −→ Δ −−+ γ for doubly charged Higgs boson (or any bilepton) production and (ii) the process γ+ e −→ q+ S/ V for scalar ( S) or vector ( V) leptoquarks (LQs). We also discuss how factorized amplitudes and radiation zeros may appear in the gauge boson fusion production of non-conjugate leptoquark pairs via γ+W ±→S i+S j ∗ in high energy e ± e ± reactions and how the zeros affect the production cross-sections for various types of scalar leptoquarks.
