Title: A New Look at SU(5) Inspired by the Diphoton PeakComments: v3: updated figure 4, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
ATLAS and CMS have just presented an excess in run 2 of the LHC at 1.4 sigma. Moreover, we consider the $\gamma\gamma$ resonance in $\lambda$SUSY. Quite simply, a drawback of this model is that it cannot account for $h \to \mu \tau$. We predict a dilaton below 700 GeV. We believe this is indicative of a shocking fact.

Title: Tension With Run 1? Interpreting the Diphoton Anomaly in Singlet-extended ModelsComments: v3: updated figure 4, conclusions unchanged, typos correctedSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
ATLAS and CMS have just reported a peak in the 13 TeV data at 3.1 sigma. We consider the $\gamma\gamma$ excess in two Higgs doublet models with new strong dynamics. Actually, the PQ symmetry protects the mass of the resonance. Charge 1/5 quarks at 600 GeV should be observed soon. We will provide more details in a future paper.

Title: An Unified Explanation for the 750 GeV Resonance and the Galactic Center ExcessAuthors: E. RazaComments: 2 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
ATLAS and CMS have just shown a resonance in the latest LHC data at 4.1 sigma. We study the phenomenology of two Higgs doublet models and derive branching ratios. The $\eta$ is produced in inelastic scattering and decays to the diphoton channel. Thus, we expect scalar singlet above 400 GeV. Our results are similar to work done by Raza and Ellis.

Title: The 750 GeV Resonance: Interpreting the $\gamma\gamma$ Anomaly in Twin HiggsComments: 2 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
ATLAS and CMS have just seen a peak in the 13 TeV data at 3.3 sigma. We analyze the 750 GeV resonance in 2HDMs with charge 2/3 quarks. The $X(750)$ is produced in photon fusion and decays to $\gamma\gamma$. Actually, the conformal symmetry protects the mass of the $\phi$, but not the Higgs. We believe this is indicative of a confusing principle.

Title: A Common Framework for the $\gamma\gamma$ Anomaly and the Doublet-triplet Splitting ProblemComments: 2 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
ATLAS and CMS have just reported an anomaly in the latest LHC data. Therefore, we consider the phenomenology of Seesaw models and analyze anomalous dimensions. Remarkably, the $\phi$ is produced in photon fusion and decays to $\gamma\gamma$. New strong dynamics at 600 GeV should be observed soon. More data should reveal the nature of the $\gamma\gamma$ peak.
