Abstract:
Production of exclusive dijets in diffractive deep inelastic e±p scattering has been measured with the ZEUS detector at HERA using an integrated luminosity of 372 pb-1. The measurement was performed for γ*p centre-of-mass energies in the range 90<250 GeV and for photon virtualities Q2>25 GeV2. Energy flows around the jet axis are presented. The cross section is presented as a function of β and ϕ, where β=x/x_IP, x is the Bjorken variable and x_IP is the proton fractional longitudinal momentum loss. The angle ϕ is defined by the γ*–dijet plane and the γ*-e± plane in the rest frame of the diffractive final state. The ϕ cross section is measured in bins of β. The results are compared to predictions from models based on different assumptions about the nature of the diffractive exchange.
