Title: On the $\gamma\gamma$ Peak
Comments: 2 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

In this letter, we address the recent diphoton excess at run 2 and natural inflation. The phenomenology of Pati-Salam models is studied and we calculate the statistical significance. The R symmetry protects the mass of the resonance, but not the Higgs. Curiously, the flavor symmetry protects the mass of the $X$. More data is likely to confirm this remarkable principle.

Title: A New Look at Seesaw Models Inspired by the Diphoton Peak
Authors: N. Chiang, N. Zhu
Comments: 23 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

In this paper, we discuss the very recent diphoton anomaly at run 2 (at 4.8 sigma). We analyze the diphoton excess in 2HDMs on a D3-brane. The $X$ couples to $WW$, but not to $hh$, decreasing tension with Run 1. Surprisingly, the R symmetry protects the mass of the $X$, but not the Higgs. Remarkably, there is much to be done.

Title: On the 750 GeV Resonance
Comments: 4 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

ATLAS and CMS have just observed a resonance in run 2 of the LHC at 4.6 sigma. We study the diphoton excess in technicolor on 3-brane. The R symmetry stabilizes the mass of the $\phi$. However, the discrete symmetry stabilizes the mass of the $S$. We will provide more details in a future paper.

Title: The 750 GeV Excess: Interpreting the $\gamma\gamma$ Peak in Gauge-extended Models
Comments: 2 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this letter, we address the very recent diphoton resonance at run 2 (at 4.7 sigma). We study the phenomenology of Georgi-Machacek models and evaluate production rates. Interestingly, the $\phi$ couples not only to $t\bar{t}$, but also to $t\bar{t}$. Charge 4/3 quarks are required at 700 GeV. Our results are similar to work done by Nomura and Li.

Title: The $\gamma\gamma$ Excess: Interpretations in the Fermi-Heisenberg Model

Subjects: High Energy Physics - Phenomenology (hep-ph)

In this note, we discuss the very recent diphoton peak at run 2 (at 4.6 sigma). We analyze the diphoton excess in AdS/CFT with exotic fermions. Interestingly, the $X$ couples to $ZZ$, but not to $t\bar{t}$, alleviating tension with Run 1. Charge 2/3 quarks are required at 900 GeV. More data is likely to confirm this remarkable rule.
