DBX (Diboson and Multilepton) Subgroup

• Conveners : K. Terashi and E. Lytken
• DBX mailing list : hn-atlas-exotics-dbx@cernSPAMNOT.ch
• Meetings : Weekly on Mondays, 14:30 at CERN. Meeting agenda

The DBX group searches for new physics with two electroweak bosons or multileptons. Main topics of interest include new heavy gauge bosons decaying to diboson, heavy neutrinos, technicolor, Randall-Sundrum Gravitons, inclusive same-sign dilepton, tri-/four-lepton inclusive searches, etc.
