Diphoton production at hadron colliders and new contact interactions
Diphoton production at hadron colliders and new contact interactions
We explore the capability of the Fermilab Tevatron and CERN LHC to place limits on the possible existence of flavor-independent qq\ifmmode\bar\else\textasciimacron\fi{}\ensuremath{\gamma}\ensuremath{\gamma} contact interactions which can lead to an excess of diphoton events with large invariant masses. Assuming no departure from the standard model is observed, we show that the Tevatron …
