Abstract

The ATLAS Collaboration has reported excesses in the search for resonant diboson production with decay modes to hadronic final states at a diboson invariant mass around 2 TeV in boosted jets from WZ, W+W, and ZZ channels. Given potential contamination, we investigate the anomalies in leptophobic U(1)LP models. We show that leptophobic models can be constructed in flipped SU(5)×U(1)X models from free fermionic string constructions and Pati-Salam models from D-brane constructions. Additionally, we perform a collider phenomenological analysis to study production cross sections for ppZjj/tt¯/WW/Zh and discover the excess can be interpreted in both the leptophobic flipped SU(5)×U(1)X models and intersecting D-branes.
