Title: A New Look at the MSSM Inspired by the $\gamma\gamma$ ResonanceAuthors: Z. YuComments: 3 pages, added refsSubjects: High Energy Physics  Phenomenology (hepph)
In this paper, we address the very recent diphoton peak at run 2 and the diboson resonance. Unsurprisingly, we scrutinize the diphoton excess in flipped SU(5) models with charge 5/3 quarks. The conformal symmetry stabilizes the mass of the resonance. Fortunately, the $\gamma\gamma$ peak implies vectorlike fermions around 700 GeV. Finally, we study the phenomenology of AdS/CFT and evaluate cross sections.

Title: Interpretations of the $\gamma\gamma$ Peak in Extensions of SU(3)^3Authors: B. NomuraComments: v2: updated figure 3, conclusions unchangedSubjects: High Energy Physics  Phenomenology (hepph)
ATLAS and CMS have just measured a resonance in run 2. The phenomenology of two Higgs doublet models is studied and we predict production rates. Consequently, the global U(1) symmetry protects the mass of the $S(750)$. Assuming the diphoton anomaly is real, we predict that new strong dynamics should be at 300 GeV. Consequently, there is much to be done.

Title: Interpretations of the $\gamma\gamma$ Resonance in Extensions of Gaugeextended ModelsAuthors: N. KimComments: 34 pagesSubjects: High Energy Physics  Phenomenology (hepph)
ATLAS and CMS have just shown a resonance in the 13 TeV data at 4.3 sigma. Curiously, we study the diphoton excess in SU(5). The $S$ couples to $WW$, but not to $Z\gamma$, alleviating tension with Run 1. The 750 GeV peak implies vectorlike quarks around 800 GeV. Our results are similar to work done by Kim and Dev.

Title: A New Take on Leftright Models Inspired by the Diphoton PeakComments: 45 pagesSubjects: High Energy Physics  Phenomenology (hepph); High Energy Physics  Theory (hepth)
In this article, we talk about the very recent diphoton anomaly at run 2 and $B \to D \tau \nu$. Curiously, the diphoton peak is analyzed in SU(5) with neutralinos. The flavor symmetry protects the mass of the $S$, but not the Higgs. New strong dynamics at 900 GeV should be observed soon. More data should reveal the nature of the diphoton anomaly.

Title: The 750 GeV Excess From Twin HiggsComments: v3: updated figure 1, conclusions unchangedSubjects: High Energy Physics  Phenomenology (hepph)
In this article, we discuss the intriguing diphoton peak at run 2. Neutralinos are added to PatiSalam models to account for the diphoton peak. The global U(1) symmetry stabilizes the mass of the $X$. Fortunately, assuming the diphoton excess is real, we predict that charge 1/5 quarks should be at 900 GeV. We leave the rest for future study.
