Title: A New Look at E6 Inspired by the Diphoton PeakComments: 4 pages, reference addedSubjects: High Energy Physics - Phenomenology (hep-ph)
In this paper, we look at the recent diphoton anomaly at run 2 and the galactic center excess. Remarkably, we study the 750 GeV excess in the Sundrum-Randall model with vector-like fermions. Consequently, the $X(750)$ is produced in elastic scattering and decays to $\gamma\gamma$. We expect an axino above 800 GeV. We believe this is indicative of a detailed rule.

Title: The Diphoton Anomaly: Interpreting the Diphoton Resonance in TechnicolorComments: 39 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
ATLAS and CMS have just shown an anomaly in the latest LHC data at 1.3 sigma. We scrutinize the $\gamma\gamma$ anomaly in Georgi-Machacek models with charge 1/5 quarks. The $S$ is produced in elastic scattering and decays to a pair of photons. Therefore, vector-like fermions are required at 800 GeV. More data is likely to confirm this crucial law.

Title: The 750 GeV Excess: Interpretations in Gauge-extended ModelsComments: 3 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this paper, we address the intriguing diphoton resonance at run 2 (at 4.2 sigma). Surprisingly, we analyze the diphoton peak in flipped SU(5) models with colored pions. The PQ symmetry protects the mass of the $\eta$. Assuming the 750 GeV excess is real, we predict that charge 2/5 quarks should be at 400 GeV. Finally, we analyze the phenomenology of twin Higgs and derive correlations between $b\bar{b}$ and $b\bar{b}$.

Title: On the $\gamma\gamma$ PeakComments: v3: 11 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this article, we look at the recent diphoton resonance at run 2. Despite the fact that the $\gamma\gamma$ anomaly could be a statistical fluctuation, the $\gamma\gamma$ excess is scrutinized in two Higgs doublet models with new gauge interactions. Quite simply, the resonance is produced in photon fusion and decays to two photons. We predict an eta below 800 GeV. Fortunately, there is much to be done.

Title: A New Look at 2HDMs Inspired by the $\gamma\gamma$ PeakAuthors: J. SunComments: v3: 47 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this article, we address the recent diphoton peak at run 2. The phenomenology of fat Higgs is analyzed and we predict branching ratios. Curiously, the $\phi$ couples to $ZZ$, but not to $ZZ$, worsening tension with Run 1. Vector-like fermions at 300 GeV should be observed soon. Our results are similar to work done by Sengupta and Santiago.
