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 gamma*-p centre-of-mass energies in the range 90 < W < 250 GeV and for photon virtualities Q(2) > 25 GeV2. Energy flows around the jet axis are presented. The cross section is presented as a function of beta and phi, where beta = x/x(P), x is the Bjorken variable and xIP is the proton fractional longitudinal momentum loss. The angle f is defined by the gamma*-dijet plane and the gamma*-e(+/-) plane in the rest frame of the diffractive final state. The f cross section is measured in bins of beta. The results are compared to predictions from models based on different assumptions about the nature of the diffractive exchange.

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 gamma-p centre-of-mass energies in the range 90 < W < 250 GeV and for photon virtualities Q(2) > 25 GeV2. Energy flows around the jet axis are presented. The cross section is presented as a function of beta and phi, where beta = x/x(P), x is the Bjorken variable and xIP is the proton fractional longitudinal momentum loss. The angle f is defined by the gamma-dijet plane and the gamma*-e(+/-) plane in the rest frame of the diffractive final state. The f cross section is measured in bins of beta. The results are compared to predictions from models based on different assumptions about the nature of the diffractive exchange.
