An upper limit to the photon fraction in cosmic rays above 10^19 eV from the Pierre Auger Observatory
Pierre Auger Collaboration
An upper limit of 16% (at 95% c.l.) is derived for the photon fraction in cosmic rays with energies greater than 10^19 eV, based on observations of the depth of shower maximum perf…

Search for eta_b in two-photon collisions at LEP II with the DELPHI detector
The DELPHI Collaboration, J. Abdallah
The pseudoscalar meson eta_b has been searched for in two-photon interactions at LEP II. The data sample corresponds to a total integrated luminosity of 617 pb^{-1} at centre-of-ma…
