IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishWe present a computation of the O(αs ) QCD corrections to W ± Z γ production at the Large Hadron Collider. The photon is considered as real, and we include full leptonic decays for the W- and Z-bosons. Based on the structure of the VBFNLO program package, we obtain numerical results via a Monte Carlo program, which allows to implement general cuts and distributions of the final-state particles. The NLO QCD corrections are sizable and strongly exceed the theory error obtained by a scale variation of the leading-order result. Also, the shapes of relevant observables are significantly altered.
