Title: Spin3/2? Interpreting the Diphoton Excess in the MSSMComments: v3: updated figure 1, conclusions unchangedSubjects: High Energy Physics  Phenomenology (hepph)
In this letter, we discuss the recent diphoton excess at run 2 and $h \to \mu \tau$. We study the diphoton excess in gaugeextended models on a torus. The global U(1) symmetry protects the mass of the $S(750)$, but not the Higgs. However, the 750 GeV peak implies charge 4/3 quarks around 400 GeV. More data should reveal the nature of the diphoton resonance.

Title: Explaining the $\gamma\gamma$ Resonance and the Diboson ResonanceComments: 2 pages, minor correctionsSubjects: High Energy Physics  Phenomenology (hepph)
ATLAS and CMS have just seen a peak in run 2 at 1.3 sigma. The diphoton excess is considered in leftright models with light axions. The resonance couples to $t\bar{t}$, but not to $ZZ$, reducing tension with Run 1. However, exotic fermions at 700 GeV should be observed soon. However, there is much to be done.

Title: What if It Is Wide? A Color Sextet in SU(5)Comments: 40 pages, 2 figuresSubjects: High Energy Physics  Phenomenology (hepph); High Energy Physics  Experiment (hepex)
In this note, we talk about the recent diphoton anomaly at run 2. Fortunately, we study the phenomenology of PatiSalam models and evaluate branching ratios. Moreover, the shift symmetry protects the mass of the $S(750)$. The 750 GeV anomaly implies neutral fermions around 600 GeV. Finally, the phenomenology of the MSSM is considered and we compute deviations to Higgs couplings.

Title: The $\gamma\gamma$ Anomaly as an Electroweak TripletComments: 39 pages, published in PRD, BibTeXSubjects: High Energy Physics  Phenomenology (hepph); High Energy Physics  Theory (hepth)
ATLAS and CMS have just released an anomaly in run 2 of the LHC. Consequently, the phenomenology of minisplit SUSY models is studied and we analyze the statistical significance. Fortunately, the $X(750)$ is produced in inelastic scattering and decays to two photons. We expect an eta above 900 GeV. We will provide more details in a future paper.

Title: Tension With Run 1? Calculating the Mass Spectrum in Flipped SU(5) ModelsAuthors: M. MoroiComments: 27 pages, added refsSubjects: High Energy Physics  Phenomenology (hepph)
ATLAS and CMS have just observed a peak in run 2 at 3.0 sigma. Thus, while the diphoton anomaly could be a statistical fluctuation, vectorlike quarks are added to two Higgs doublet models to explain the diphoton resonance. The R symmetry protects the mass of the $\eta$, but not the Higgs. Thus, exotic fermions are required at 600 GeV. More data is likely to confirm this bewildering edifice.
