Title: The 750 GeV Anomaly as a KK Graviton
Authors: S. Wu
Comments: v3: updated figure 1, conclusions unchanged
Subjects: High Energy Physics - Phenomenology (hep-ph)

A few months ago, ATLAS and CMS have measured a resonance in run 2 of the LHC. The phenomenology of SU(5) is analyzed and we compute 4-body decays. A downside of this model is that it is very predictive. Consequently, the diphoton anomaly implies conformal dynamics around 300 GeV. We leave the rest for future study.

Title: A Common Framework for the Diphoton Anomaly and the Diboson Resonance

ATLAS and CMS have just released a peak in the 13 TeV data at 3.7 sigma. Fortunately, we study the diphoton peak in the Heisenberg-Coleman model. Interestingly, the $S(750)$ couples to $WW$, but not to $b\bar{b}$, worsening tension with Run 1. Heavy scalars are required at 900 GeV. Finally, we scrutinize the diphoton peak in Seesaw models on warped metric.

Title: Interpretations of the 750 GeV Resonance in Extensions of the Broken MRSSM
Comments: v3: added refs

In this letter, we look at the very recent diphoton excess at run 2. Fortunately, we study the 750 GeV resonance in left-right models on warped metric. The flavor symmetry protects the mass of the resonance, but not the Higgs. Thus, the 750 GeV resonance implies neutral fermions around 400 GeV. More data should reveal the nature of the diphoton excess.

Title: Can It Be Wide? A Color Sextet in Left-right Models

ATLAS and CMS have just presented a resonance in run 2 of the LHC. Despite the fact that the diphoton peak could be a statistical fluctuation, heavy scalars are added to singlet-extended models to explain the diphoton peak. Consequently, the conformal symmetry protects the mass of the $S$. Assuming the 750 GeV excess is real, we predict that exotic fermions should be at 500 GeV. Given this, our work may seem quite arresting.

Title: The Diphoton Anomaly From GUT Models

In this note, we discuss the very recent diphoton anomaly at run 2. We consider the 750 GeV peak in flipped SU(5) models. A feature of this model is that $ZZ$ and $t\bar{t}$ are predicted to be huge. However, the $\gamma\gamma$ anomaly implies colored pions around 900 GeV. More data is likely to confirm this important framework.
