A dedicated sample of Large Hadron Collider proton-proton collision data at centre-of-mass energy s√=8 TeV is used to study inclusive single diffractive dissociation, pp→Xp. The intact final-state proton is reconstructed in the ATLAS ALFA forward spectrometer, while charged particles from the dissociated system X are measured in the central detector components. Cross sections are measured differentially as functions of the proton fractional energy loss ξ, the squared four-momentum transfer t, and Δη, a variable that characterises the rapidity gap separating the proton and the system X. The data are consistent with an exponential t dependence, dσ/dt∝eBt with slope parameter B=7.65±0.34 GeV−2. Interpreted in the framework of Regge phenomenology, the ξ dependence leads to a pomeron intercept of α(0)=1.07±0.09.
