Search for Randall-Sundrum Gravitons in the Dielectron and Diphoton Final States with5.4 fb−1of Data frompp¯Collisions ats=1.96 TeV
Using 5.4 fb-1 of integrated luminosity from ppbar collisions at sqrt(s)=1.96 TeV collected by the D0 detector at the Fermilab Tevatron Collider, we search for decays of the lightest Kaluza-Klein mode of the graviton in the Randall-Sundrum model to ee and gammagamma. We set 95% C.L. lower limits on the mass of the lightest graviton between 560 GeV and 1050 GeV for values of the coupling k/Mbar_pl between 0.01 and 0.1.
Search for Diphoton Events with Large Missing Transverse Energy in6.3 fb−1ofpp¯Collisions ats=1.96 TeV
We report a search for diphoton events with large missing transverse energy produced in p (p) over bar collisions at root s = 1.96 TeV. The data were collected with the D0 detector at the Fermilab ...
