Title: The Diphoton Peak From AdS/CFTAuthors: C. SantiagoComments: v2: 46 pages, minor changesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
Just recently, ATLAS and CMS have measured a peak in run 2 of the LHC. We study the phenomenology of left-right models and calculate mass ratios. The $S$ is produced in photon fusion and decays to $\gamma\gamma$. Actually, the 750 GeV resonance implies charge 8/3 quarks around 800 GeV. We will provide more details in a future paper.

Title: A New Look at Left-right Models Inspired by the $\gamma\gamma$ PeakComments: 29 pages, JHEP3Subjects: High Energy Physics - Phenomenology (hep-ph)
In this article, we discuss the recent diphoton anomaly at run 2 (at 3.8 sigma). The phenomenology of fat Higgs is scrutinized and we analyze mass ratios. The discrete symmetry stabilizes the mass of the $\eta$. Therefore, conformal dynamics are required at 300 GeV. More data should reveal the nature of the diphoton excess.

Title: The $\gamma\gamma$ Resonance: A Heavy Pion in Composite ModelsAuthors: T. WuComments: v4: updated figure 3, conclusions unchanged, added refs, Latex file, added refs, minor changesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
ATLAS and CMS have just presented an excess in the latest LHC data at 1.5 sigma. We analyze the phenomenology of E6 and derive 4-body decays. The $S$ couples to $ZZ$, but not to $b\bar{b}$, decreasing tension with Run 1. Unfortunately, the shift symmetry protects the mass of the resonance. Given this, our work may seem quite critical.

Title: The 750 GeV Excess as a Heavy PionAuthors: J. HalversonComments: 25 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
Just recently, ATLAS and CMS have released an anomaly in the latest LHC data. Thus, despite the fact that the 750 GeV resonance could be a statistical fluctuation, the phenomenology of Seesaw models is studied and we calculate production rates. Quite simply, the flavor symmetry protects the mass of the $S$. We predict a sgoldstino below 500 GeV. More data should reveal the nature of the 750 GeV anomaly.

Title: The Diphoton Anomaly: Calculating the Mass Spectrum in the MSSMComments: 41 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just shown a peak in the second run of the LHC. Fortunately, we analyze the 750 GeV resonance in flipped SU(5) models on AdS_5. The global U(1) symmetry protects the mass of the $S$, but not the Higgs. Quite simply, we predict a pseudo Nambu Goldstone boson below 600 GeV. Our results are similar to work done by Royon.
