Description

The photoproduction reaction γp→ μ+μ- p has been studied in ep interaction using the ZEUS detector at HERA. The Upsilon vector meson has been observed in a data sample corresponding to the full HERA I and II statistics. The γp cross section for Upsilon production is presented as a function of W in the range 60<W< 220 GeV and compared to theory and other measurements
