ATLAS and CMS have just shown a resonance in the latest LHC data. We study the 750 GeV peak in singlet-extended models. Curiously, the $\eta$ couples not only to $b\bar{b}$, but also to $Z\gamma$. The $\gamma\gamma$ resonance implies vector-like quarks around 500 GeV. Finally, we analyze the 750 GeV excess in the NMSSM with exotic fermions.

Title: The 750 GeV Excess From SU(5)
Comments: 24 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

ATLAS and CMS have just released an excess in the 13 TeV data at 4.0 sigma. We scrutinize the phenomenology of SU(5) and compute correlations between $WW$ and $hh$. A feature of this model is that it is very predictive. Surprisingly, the diphoton excess implies neutral fermions around 800 GeV. Given this, our work may seem quite unexpected.

Title: The Diphoton Resonance From Technicolor
Authors: R. Perez
Comments: v4: added refs, BibTeX
Subjects: High Energy Physics - Phenomenology (hep-ph)

ATLAS and CMS have just observed an excess in run 2 of the LHC. The phenomenology of $\lambda$SUSY is analyzed and we evaluate deviations to Higgs couplings. In short, the $\phi$ is produced in vector boson fusion and decays to $\gamma\gamma$. The $\gamma\gamma$ peak implies light axions around 300 GeV. More data should reveal the nature of the 750 GeV anomaly.

Title: Interpretations of the $\gamma\gamma$ Excess in Extensions of SO(10)
Authors: E. Hubisz
Comments: 34 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this article, we talk about the intriguing diphoton excess at run 2 (at 1.5 sigma). We analyze the diphoton excess in minisplit SUSY models. Interestingly, the $X$ couples to $WW$, but not to $b\bar{b}$, increasing tension with Run 1. Neutralinos are required at 600 GeV. More data is likely to confirm this elaborate rule.

Title: Interpretations of the 750 GeV Peak in GUT Models
Comments: 3 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

ATLAS and CMS have just reported a peak in the second run of the LHC at 3.4 sigma. Curiously, we consider the diphoton peak in folded SUSY. The $\eta$ couples to $ZZ$, but not to $Z\gamma$, increasing tension with Run 1. Therefore, we expect a KK gluon above 900 GeV. We leave the rest for future study.
