Interpretations of the ATLAS Diboson Anomaly

High Energy Physics - Phenomenology 2015-11-18 v4 High Energy Physics - Experiment

Abstract

Recently, the ATLAS Collaboration recorded an interesting anomaly in diboson production with excesses at the diboson invariant mass around 2 TeV in boosted jets of all the WZWZ, W+WW^+ W^-, and ZZZZ channels. We offer a theoretical interpretation of the anomaly using a phenomenological right-handed model with extra WW' and ZZ' bosons. Constraints from narrow total decay widths, dijet cross sections, and W/Z+HW/Z + H production are taken into account. We also comment on a few other possibilities.

v4: match the published version; v3: 18 pages, 6 figures, change to leptophobic Z' model to take into account the EW constraints, and some updates to the analysis and text; v2: 17 pages, 7 figures; a new section and a new figure are added; correct the statement about the WH; references are also added
