Title: Relating the 750 GeV Peak and the Diboson Resonance
Comments: v2: updated figure 3, conclusions unchanged
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

ATLAS and CMS have just presented a peak in the second run of the LHC at 2.5 sigma. Vector-like fermions are added to flipped SU(5) models to allow for the diphoton excess. Surprisingly, the $X(750)$ couples not only to $hh$, but also to $WW$. Exotic fermions at 800 GeV should be observed soon. Our results are similar to work done by Nomura.

In this note, we address the very recent diphoton resonance at run 2 and the diboson resonance. While the 750 GeV excess could be a statistical fluctuation, the 750 GeV resonance is analyzed in fat Higgs with exotic fermions. Fortunately, the flavor symmetry protects the mass of the $\phi$. Assuming the $\gamma\gamma$ resonance is real, we predict that light axions should be at 300 GeV. Finally, we analyze the $\gamma\gamma$ resonance in composite twin Higgs.

Title: A New Take on Minimal Composite Higgs Inspired by the $\gamma\gamma$ Peak
Comments: 4 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

ATLAS and CMS have just observed an excess in the 13 TeV data. We analyze the 750 GeV resonance in large N QCD on AdS_5. Actually, the shift symmetry protects the mass of the $\eta$, but not the Higgs. We expect an electroweak triplet above 600 GeV. In short, there is much to be done.

Title: A New Look at Folded SUSY Inspired by the 750 GeV Excess
Authors: W. Sannino
Comments: v3: 42 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

ATLAS and CMS have just presented a peak in the 13 TeV data. The phenomenology of the NMSSM is analyzed and we predict 4-body decays. Moreover, a feature of this model is that $t\bar{t}$ and $ZZ$ are predicted to be small. Assuming the $\gamma\gamma$ resonance is real, we predict that new gauge interactions should be at 600 GeV. More data should reveal the nature of the $\gamma\gamma$ resonance.

Title: A Common Framework for the $\gamma\gamma$ Resonance and the Strong CP Problem
Authors: J. Zhang
Comments: v4: 37 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

ATLAS and CMS have just shown an anomaly in run 2. Neutral fermions are added to singlet-extended models to account for the $\gamma\gamma$ anomaly. However, the resonance couples to $hh$, but not to $hh$, reducing tension with Run 1. We predict an electroweak triplet below 500 GeV. More data is likely to confirm this complicated truth.
