Title: Spin-3/2? Interpreting the Diphoton Excess in the MSSMComments: v3: updated figure 1, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph)
In this letter, we discuss the recent diphoton excess at run 2 and $h \to \mu \tau$. We study the diphoton excess in gauge-extended 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 (hep-ph)
ATLAS and CMS have just seen a peak in run 2 at 1.3 sigma. The diphoton excess is considered in left-right 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 (hep-ph); High Energy Physics - Experiment (hep-ex)
In this note, we talk about the recent diphoton anomaly at run 2. Fortunately, we study the phenomenology of Pati-Salam 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 (hep-ph); High Energy Physics - Theory (hep-th)
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 (hep-ph)
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, vector-like 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.
