Collider Bounds on Pseudoscalars Coupling to Gauge Bosons
Matthew Kleban, Raul Rabadan
Abstract
We bound the coupling of pseudo-scalar particles to Tr GGQCD using (the lack of) monojet plus missing ET events at the Tevatron, and estimate the bounds obtainable from LHC. In addition, we revisit the bounds on the coupling to FFEM from e+e- collider events with single photon and missing ET final states. This is especially interesting in light of the recent experimental results from the PVLAS collaboration, which we believe can be tested by data which will be available in the near future.
