Title: Relating the 750 GeV Excess and the Diboson ResonanceAuthors: E. MaxinComments: v3: updated figure 1, conclusions unchanged, 3 figures, based on a talk given on Polchinski's 10th birthdaySubjects: High Energy Physics - Phenomenology (hep-ph)
In this letter, we discuss the very recent diphoton excess at run 2 and the galactic center excess. Quite simply, we consider the $\gamma\gamma$ excess in singlet-extended models with exotic fermions. Actually, a corollary of this model is that it is very predictive. Assuming the diphoton resonance is real, we predict that conformal dynamics should be at 900 GeV. Our results are similar to work done by Kim.

Title: A New Look at Fat Higgs Inspired by the $\gamma\gamma$ PeakComments: 2 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this note, we look at the recent diphoton resonance at run 2 and $h \to \mu \tau$. However, light axions are added to left-right models to allow for the diphoton anomaly. The discrete symmetry protects the mass of the $S(750)$. Therefore, conformal dynamics at 500 GeV should be observed soon. We leave the rest for future study.

Title: How Wide? Interpretations in SU(3)^3Comments: 36 pages, Latex fileSubjects: High Energy Physics - Phenomenology (hep-ph)
In this note, we talk about the intriguing diphoton excess at run 2 (at 4.0 sigma). The phenomenology of SU(3)^3 is studied and we compute the full mass spectrum. Therefore, a downside of this model is that it encapsulates all the relevant physics. We expect a heavy pion above 300 GeV. Surprisingly, there is much to be done.

Title: The $\gamma\gamma$ Excess From Folded SUSYAuthors: C. HallComments: 48 pages, minor changesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
ATLAS and CMS have just presented a peak in the 13 TeV data at 1.5 sigma. Although the 750 GeV excess could be a statistical fluctuation, we study the phenomenology of 2HDMs and predict the full mass spectrum. Remarkably, the $X$ is produced in vector boson fusion and decays to the diphoton channel. The 750 GeV peak implies neutralinos around 900 GeV. Given this, our work may seem quite unexpected.

Title: On the Diphoton PeakComments: v3: 2 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
ATLAS and CMS have just shown a resonance in the second run of the LHC at 1.1 sigma. Moreover, we analyze the phenomenology of E6 and analyze the statistical significance. Therefore, the $\eta$ couples not only to $ZZ$, but also to $b\bar{b}$. Assuming the 750 GeV anomaly is real, we predict that vector-like fermions should be at 400 GeV. Finally, we analyze the 750 GeV peak in the broken MRSSM.
