Title: The $\gamma\gamma$ Anomaly From Gauge-extended ModelsComments: v3: updated figure 2, conclusions unchanged, added refs, added refs, 2 tablesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this letter, we discuss the very recent diphoton anomaly at run 2. The diphoton anomaly is considered in the MSSM with light axions. A downside of this model is that it encapsulates all the relevant physics. Thus, the $X$ couples to $hh$, but not to $Z\gamma$, removing tension with Run 1. Our results are similar to work done by Mawatari.

Title: The $\gamma\gamma$ Excess: An Axion in SU(5)Comments: v4: 4 pages, JHEP3Subjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just released a resonance in the second run of the LHC. Thus, while the 750 GeV anomaly could be a statistical fluctuation, light axions are added to 2HDMs to allow for the $\gamma\gamma$ excess. Moreover, the resonance is produced in photon fusion and decays to two photons. Neutral fermions at 600 GeV should be observed soon. Our results are similar to work done by Chakraborty.

Title: A New Take on AdS/CFT Inspired by the Diphoton ExcessComments: 15 pagesSubjects: 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 and the galactic center excess. Thus, we consider the phenomenology of GUT models and derive the full mass spectrum. A downside of this model is that it explains the 2 TeV resonance. However, we expect an eta prime above 600 GeV. We leave the rest for future study.

Title: The $\gamma\gamma$ Excess as an Electroweak TripletComments: 3 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
Recently, ATLAS and CMS have presented an excess in run 2 of the LHC. We consider the diphoton anomaly in two Higgs doublet models on 3-brane. The resonance couples not only to $Z\gamma$, but also to $Z\gamma$. In short, the $X$ is produced in elastic scattering and decays to two photons. Our results are similar to work done by Zhu and Okada.

Title: The 750 GeV Anomaly: Interpreting the Diphoton Peak in Fat HiggsAuthors: C. Ren, L. Kim, E. Wang, V. Tesi, E. Dey, P. Marzocca, J. Nomura, E. Yanagida, G. Aydemir, H. YangComments: 2 pages, Latex fileSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just seen an excess in run 2 at 1.6 sigma. The 750 GeV peak is considered in Georgi-Machacek models with new gauge interactions. The flavor symmetry protects the mass of the $\eta$, but not the Higgs. Actually, the $\phi$ couples to $hh$, but not to $b\bar{b}$, reducing tension with Run 1. Given this, our work may seem quite simple.
