The ATLAS Forward Proton Programme

The ATLAS Forward Proton Programme - talk for the Low-x 2012 Meeting Quartic anomalous couplings measurement at μ = 46 and a total luminosity of 300 fb−1 is possible. The full AFP simulation in presence of pile-up confirms the gain in sensitivity between one and two orders of magnitude with respect to the standard (non-AFP) ATLAS methods. The use of the AFP allows reaching the values expected in Higgs-less or extra-dimension models. The production of exclusive dijet for μ = 23 and a total luminosity of 40 fb−1 the measurement is possible and interesting due to the huge model uncertainties at present level of the theory understanding. The measurement of the W asymmetry in a specific configuration at low μ allows to get a decisive understanding on the diffractive exchange. For all physics cases, AFP capabilities in terms of proton tagging and timing resolution are key and unique features unprecedented sensitivity to quartic anomalous coupling or novel QCD measurements.
