Title: The 750 GeV Peak as a KK Graviton
Comments: v4: 26 pages, added refs, reference added
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

In this article, we discuss the very recent diphoton resonance at run 2 (at 2.9 sigma). We scrutinize the phenomenology of twin Higgs and calculate mass ratios. The conformal symmetry stabilizes the mass of the $\eta$. Therefore, the $\eta$ is produced in gluon fusion and decays to two photons. We believe this is indicative of a startling fact.

Title: Interpretations of the Diphoton Peak in Fat Higgs
Authors: K. Park
Comments: 48 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this letter, we talk about the recent diphoton peak at run 2 and the galactic center excess. Moreover, exotic fermions are added to E6 to allow for the diphoton anomaly. The $X(750)$ couples not only to $WW$, but also to $ZZ$. Vector-like fermions at 500 GeV should be observed soon. Our results are similar to work done by Chao and Strassler.

Title: Interpretations of the 750 GeV Anomaly in Split SUSY Models
Authors: L. Wang, X. Li
Comments: 4 pages, Latex file
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this paper, we discuss the intriguing diphoton peak at run 2 (at 3.5 sigma). We analyze the diphoton resonance in flipped SU(5) models. Surprisingly, a downside of this model is that it cannot account for the doublet-triplet splitting problem. We predict a color sextet below 800 GeV. We leave the rest for future study.

Title: Spin-2? Calculating the NLO Cross Section in Fat Higgs
Comments: 3 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

In this paper, we talk about the intriguing diphoton resonance at run 2 and the doublet-triplet splitting problem. We scrutinize the phenomenology of large N QCD and predict decay widths. Remarkably, the shift symmetry stabilizes the mass of the $X$. Vector-like quarks are required at 600 GeV. Curiously, there is much to be done.

Title: The 750 GeV Resonance From the Broken MRSSM
Authors: B. Han, D. Wang
Comments: 2 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

In this paper, we discuss the intriguing diphoton resonance at run 2 and the diboson resonance. In short, the 750 GeV anomaly is analyzed in SU(3)^3 with light axions. The $\phi$ couples to $b\bar{b}$, but not to $b\bar{b}$, worsening tension with Run 1. Therefore, assuming the 750 GeV peak is real, we predict that charge 1/3 quarks should be at 800 GeV. Moreover, there is much to be done.
