Bosonic quartic couplings at CERN LHC

We analyze the potential of the CERN Large Hadron Collider to study anomalous quartic vector-boson interactions [Formula Presented] [Formula Presented] [Formula Presented] and [Formula Presented] through the weak boson fusion processes [Formula Presented] and [Formula Presented] with [Formula Presented] or [Formula Presented] After a careful study of the backgrounds and how to extract them from the data, we show that the process [Formula Presented] is potentially the most sensitive to deviations from the standard model, improving the sensitivity to anomalous couplings by up to a factor of [Formula Presented] with respect to the present direct (indirect) limits.
