Search for light gravitinos in events with photons and missing transverse momentum at HERA

Å. Aktas, Vladimir Andreev, T. Anthonis, A. Asmone et autres

A search for gravitinos produced in e±p collisions is performed using the H1 detector at HERA. The data were taken at a centre-of-mass energy of 319 GeV and correspond to an integrated luminosity of 64.3 pb−1 for e+p collisions and 13.5 pb−1 …
