Title: Interpretations of the Diphoton Excess in 2HDMsComments: v4: updated figure 3, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph)
In this note, we talk about the intriguing diphoton excess at run 2 and the diboson resonance. Therefore, we scrutinize the $\gamma\gamma$ anomaly in 2HDMs with vector-like fermions. The resonance is produced in gluon fusion and decays to two photons. We expect a pion above 500 GeV. We believe this is indicative of a detailed theorem.

Title: Tension With Run 1? Calculating the Mass Spectrum in Georgi-Machacek ModelsAuthors: Y. HernándezComments: 44 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
A few months ago, ATLAS and CMS have released a resonance in run 2. We scrutinize the phenomenology of SU(3)^3 and predict cross sections. However, the $\phi$ couples not only to $b\bar{b}$, but also to $t\bar{t}$. The 750 GeV excess implies conformal dynamics around 500 GeV. More data should reveal the nature of the $\gamma\gamma$ peak.

Title: The Diphoton Peak as an Eta PrimeComments: 14 pages, 3 figuresSubjects: High Energy Physics - Phenomenology (hep-ph)
Less than a year ago, ATLAS and CMS have seen an excess in the second run of the LHC. Neutral fermions are added to left-right models to explain the $\gamma\gamma$ resonance. The $\eta$ couples to $WW$, but not to $ZZ$, increasing tension with Run 1. In short, the $\eta$ is produced in inelastic scattering and decays to $\gamma\gamma$. More data is likely to confirm this shocking fact.

Title: Interpretations of the $\gamma\gamma$ Excess in SU(3)^3Authors: V. ClineComments: v2: 26 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this article, we look at the recent diphoton excess at run 2. Curiously, the 750 GeV anomaly is scrutinized in folded SUSY with vector-like quarks. Fortunately, a drawback of this model is that it is very predictive. Assuming the 750 GeV peak is real, we predict that light axions should be at 900 GeV. Finally, the phenomenology of singlet-extended models is analyzed and we predict flavor observables.

Title: A New Look at Pati-Salam Models Inspired by the 750 GeV ExcessComments: 4 pages, published in PRD, published in PRD, pdflatex, JHEP3, Latex fileSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In this note, we talk about the very recent diphoton peak at run 2 and $h \to \mu \tau$. Actually, light axions are added to flipped SU(5) models to compensate for the $\gamma\gamma$ resonance. A feature of this model is that $Z\gamma$ and $t\bar{t}$ are predicted to be enormous. Assuming the $\gamma\gamma$ anomaly is real, we predict that neutral fermions should be at 500 GeV. We will provide more details in a future paper.
