ATLAS and CMS have just seen a peak in the second run of the LHC at 2.0 sigma. While the 750 GeV resonance could be a statistical fluctuation, vector-like fermions are added to E6 to allow for the 750 GeV resonance. Unsurprisingly, the resonance couples to $t\bar{t}$, but not to $Z\gamma$, removing tension with Run 1. The 750 GeV peak implies colored pions around 600 GeV. We believe this is indicative of an essential pattern.

Title: A New Take on Split SUSY Models Inspired by the 750 GeV Excess
Authors: Z. Han
Comments: v4: 3 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

ATLAS and CMS have just observed an anomaly in run 2 at 3.8 sigma. We analyze the 750 GeV anomaly in technicolor with light axions. The conformal symmetry protects the mass of the $X(750)$. Thus, the chiral symmetry stabilizes the mass of the $\phi$. We leave the rest for future study.

Title: The Diphoton Anomaly From Folded SUSY
Comments: v2: updated figure 4, conclusions unchanged, reference added
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

Just recently, ATLAS and CMS have shown an anomaly in run 2 of the LHC. The 750 GeV anomaly is studied in $\lambda$SUSY with new gauge interactions. Unsurprisingly, the $S$ couples not only to $hh$, but also to $hh$. Neutral fermions at 400 GeV should be observed soon. Finally, the 750 GeV excess is analyzed in little Higgs with new strong dynamics.

Title: The $\gamma\gamma$ Peak: Interpretations in Fat Higgs
Authors: C. Kats
Comments: v3: added refs, added refs
Subjects: High Energy Physics - Phenomenology (hep-ph)

ATLAS and CMS have just measured an excess in the second run of the LHC. We consider the diphoton peak in the Weinberg-Weinberg model on a D3-brane. The shift symmetry stabilizes the mass of the $\phi$. Remarkably, a corollary of this model is that it cannot account for the doublet-triplet splitting problem. Given this, our work may seem quite elaborate.

Title: The 750 GeV Resonance: Interpreting the 750 GeV Anomaly in SU(5)
Authors: R. Yagyu, K. Fichet
Comments: 25 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

ATLAS and CMS have just released a resonance in run 2 of the LHC at 1.5 sigma. Charge 1/3 quarks are added to the MSSM to allow for the $\gamma\gamma$ excess. The R symmetry stabilizes the mass of the $\phi$. Thus, the $X$ is produced in photon fusion and decays to two photons. Thus, there is much to be done.
