Title: A New Look at Composite Models Inspired by the 750 GeV PeakComments: 4 pages, published in PRD, typos correctedSubjects: High Energy Physics - Phenomenology (hep-ph)
In this paper, we talk about the intriguing diphoton excess at run 2 (at 3.6 sigma). We consider the diphoton anomaly in Seesaw models on a torus. The $\phi$ is produced in photon fusion and decays to the diphoton channel. Curiously, a drawback of this model is that it cannot account for $h \to \mu \tau$. More data is likely to confirm this crucial truth.

Title: The $\gamma\gamma$ Peak: Interpreting the Diphoton Resonance in GUT ModelsComments: v4: 3 pages, added refs, JHEP3Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
ATLAS and CMS have just measured an excess in the 13 TeV data at 2.7 sigma. Unfortunately, the phenomenology of minisplit SUSY models is studied and we derive branching ratios. The R symmetry stabilizes the mass of the resonance. Unsurprisingly, the $\gamma\gamma$ peak implies vector-like quarks around 700 GeV. We believe this is indicative of a fundamental edifice.

Title: Relating the Diphoton Resonance and $h \to \mu \tau$Comments: v2: updated figure 2, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this note, we look at the very recent diphoton excess at run 2 (at 3.9 sigma). Unfortunately, the diphoton peak is considered in E6 with exotic fermions. However, the PQ symmetry protects the mass of the resonance. Assuming the 750 GeV resonance is real, we predict that new strong dynamics should be at 300 GeV. Our results are similar to work done by Bi.

Title: The $\gamma\gamma$ Resonance as an EtaComments: 22 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just released a resonance in run 2 at 3.5 sigma. We study the phenomenology of the broken MRSSM and analyze flavor observables. The $\phi$ couples to $WW$, but not to $hh$, worsening tension with Run 1. Moreover, we expect a pion above 600 GeV. Finally, we consider the diphoton excess in folded SUSY with colored pions.

Title: The 750 GeV Anomaly From Two Higgs Doublet ModelsAuthors: B. GogoladzeComments: 16 pages, JHEP3Subjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just seen an excess in run 2 of the LHC. Actually, despite the fact that the $\gamma\gamma$ peak could be a statistical fluctuation, we analyze the 750 GeV peak in singlet-extended models with light axions. A corollary of this model is that it cannot account for the core-cusp problem. In short, we expect a pion above 900 GeV. However, there is much to be done.
