Title: Connecting the $\gamma\gamma$ Resonance and $B \to D \tau \nu$Comments: v2: 34 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this paper, we discuss the recent diphoton peak at run 2. Actually, we study the $\gamma\gamma$ anomaly in technicolor. The $X(750)$ couples not only to $hh$, but also to $ZZ$. New strong dynamics are required at 400 GeV. Given this, our work may seem quite beautiful.

Title: Interpretations of the Diphoton Anomaly in Extensions of 2HDMsAuthors: M. YuComments: v3: added refsSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just shown a resonance in run 2 of the LHC at 3.0 sigma. Quite simply, we consider the phenomenology of flipped SU(5) models and analyze 4-body decays. A downside of this model is that it is very predictive. We expect an eta above 500 GeV. Our results are similar to work done by Quevillon.

Title: Interpretations of the Diphoton Excess in Seesaw ModelsAuthors: L. AustriComments: v3: added refs, added refsSubjects: High Energy Physics - Phenomenology (hep-ph)
In this letter, we talk about the intriguing diphoton resonance at run 2 (at 4.0 sigma). The $\gamma\gamma$ anomaly is analyzed in left-right models with neutral fermions. Consequently, the R symmetry stabilizes the mass of the $S$. Assuming the diphoton excess is real, we predict that new strong dynamics should be at 300 GeV. Our results are similar to work done by Okada and Shang.

Title: A New Look at SO(10) Inspired by the 750 GeV PeakComments: v2: updated figure 2, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph)
In this paper, we talk about the recent diphoton peak at run 2 and the galactic center excess. However, neutral fermions are added to minisplit SUSY models to allow for the 750 GeV excess. Curiously, the chiral symmetry protects the mass of the $S(750)$, but not the Higgs. Assuming the diphoton resonance is real, we predict that light axions should be at 900 GeV. We leave the rest for future study.

Title: A Common Framework for the Diphoton Excess and Muon g-2Comments: v3: updated figure 4, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph)
In this paper, we discuss the recent diphoton anomaly at run 2. Fortunately, vector-like quarks are added to singlet-extended models to explain the diphoton excess. Moreover, the $\eta$ couples to $b\bar{b}$, but not to $b\bar{b}$, removing tension with Run 1. Neutralinos are required at 300 GeV. More data is likely to confirm this ingenious structure.
