Interpretations of the ATLAS Diboson Anomaly

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 $WZ$, $W^{+}{W}^{-}$, and $ZZ$ channels. We offer a theoretical interpretation of the anomaly using a phenomenological right-handed model with extra $W^{\prime }$ and $Z^{\prime }$ bosons. Constraints from narrow total decay widths, dijet cross sections, and $W/Z+H$ 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
