TL;DR: A search for single photons, produced in e + e − collisions together with particles interacting only weakly with matter, has been performed using the CELLO detector operating at the PETRA storage ring as discussed by the authors.

TL;DR: Using the CELLO detector at PETRA, a search has been made for excited leptons by studying e + e − interactions which yield l + l − γγ, l + γ and γ γ final states, where l =e,μ or τ as discussed by the authors.

TL;DR: In this article, a search for light leptoquarks decaying into a lepton and a quark has been performed using the CELLO detector at the storage ring PETRA.

TL;DR: In this article, the production of excited quarks has been looked for in e + e − interactions at PETRA at center of mass energies up to 46.8 GeV using the CELLO detector.
