Title: A New Take on Singlet-extended Models Inspired by the Diphoton Resonance
Comments: 40 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this paper, we discuss the intriguing diphoton peak at run 2. We analyze the phenomenology of SU(3)^3 and analyze branching ratios. Therefore, the $X$ couples not only to $t\bar{t}$, but also to $Z\gamma$. We expect a pseudoscalar above 300 GeV. More data should reveal the nature of the 750 GeV resonance.

Title: On the $\gamma\gamma$ Excess
Comments: v4: added refs, minor corrections
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this note, we talk about the intriguing diphoton resonance at run 2 (at 3.5 sigma). We study the diphoton excess in Georgi-Machacek models. The discrete symmetry protects the mass of the $S(750)$, but not the Higgs. Therefore, the resonance couples to $t\bar{t}$, but not to $ZZ$, removing tension with Run 1. We leave the rest for future study.

Title: A New Look at Seesaw Models Inspired by the 750 GeV Peak
Comments: 3 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

In this article, we address the intriguing diphoton resonance at run 2. Surprisingly, we scrutinize the phenomenology of little Higgs and evaluate decay widths. The $S(750)$ couples to $WW$, but not to $ZZ$, alleviating tension with Run 1. Unfortunately, assuming the diphoton resonance is real, we predict that neutralinos should be at 300 GeV. More data should reveal the nature of the diphoton anomaly.

Title: The Diphoton Excess From Large N QCD
Comments: 3 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

ATLAS and CMS have just measured a resonance in run 2 at 3.8 sigma. Thus, while the $\gamma\gamma$ anomaly could be a statistical fluctuation, the phenomenology of left-right models is studied and we analyze production rates. The $\phi$ couples to $hh$, but not to $WW$, reducing tension with Run 1. Exotic fermions are required at 900 GeV. Given this, our work may seem quite arresting.

Title: The $\gamma\gamma$ Resonance as Scalar Singlet
Comments: v2: 4 pages, JHEP3
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

In this note, we address the intriguing diphoton peak at run 2 and the core-cusp problem. We study the phenomenology of AdS/CFT and compute the statistical significance. Consequently, the global U(1) symmetry protects the mass of the resonance, but not the Higgs. Vector-like fermions at 700 GeV should be observed soon. We leave the rest for future study.
