Inclusive Measurement of Diffractive Deep Inelastic Scattering at HERA.

Emmanuel Sauvan
The diffractive process $ep \rightarrow eXY$, where $Y$ denotes a proton or its low mass excitation having $M_Y < 1.6$~GeV, is studied with the H1 experiment at HERA. Triple differential cross sections are measured as a function of the photon virtuality $Q^2$, the longitudinal momentum fraction of the incident proton carried by the colourless exchange $x_{\pom}$ and $\beta=x/x_{\pom}$, where x is the Bjorken scaling variable. These measurements are made after selecting diffractive events by demanding...
