Title:  Top Quark Multilepton Signatures as a Window to New Physics

Refreshments available at 1:30 pm.

Date: Tue, 02 Oct 2018, 1:45 pm – 2:45 pm
Type: Seminar
Location: 1400 BPS Bldg.

The top quark multilepton signatures is charac­terized by two same-sign leptons or three or more lep­tons, accom­panied by several jets, at least one of which is b-tagged. This signa­ture results from a num­ber of interest­ing pro­cesses, including single and top quark pair pro­duction in associa­tion with addi­tional bosons (W, Z, and H) as well as four-top pro­duction. The LHC is just reach­ing the sensi­tivity to make measure­ments of many of these pro­cesses. This talk will re­view the status of measure­ments of pro­cesses that con­tribute to the top quark multi­lepton sig­nature, and will dis­cuss ways in which this top quark multil­epton events can be used to search for new physics.
