Title: On the $\gamma\gamma$ AnomalyAuthors: V. GaoComments: 18 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
Just recently, ATLAS and CMS have observed an anomaly in the second run of the LHC. The $\gamma\gamma$ anomaly is studied in the NMSSM with charge 8/3 quarks. A downside of this model is that it is very predictive. Quite simply, the $\gamma\gamma$ peak implies vector-like fermions around 700 GeV. Finally, vector-like fermions are added to GUT models to compensate for the 750 GeV resonance.

Title: The 750 GeV Resonance From Gauge-extended ModelsComments: 42 pages, 3 tablesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this paper, we look at the recent diphoton resonance at run 2 (at 1.4 sigma). Thus, we analyze the phenomenology of AdS/CFT and predict correlations between $Z\gamma$ and $ZZ$. Curiously, the $\phi$ is produced in vector boson fusion and decays to $\gamma\gamma$. We expect a KK graviton above 600 GeV. Our results are similar to work done by Kobakhidze.

Title: Interpretations of the $\gamma\gamma$ Anomaly in Extensions of $\lambda$SUSYAuthors: L. Moretti, D. Sun, I. Yang, N. Mandal, W. Kundu, D. Wang, S. Nomura, M. Wang, Y. Dev, I. YangComments: 4 pages, no figures, published in PRDSubjects: High Energy Physics - Phenomenology (hep-ph)
In this article, we look at the very recent diphoton excess at run 2 (at 3.8 sigma). Heavy scalars are added to two Higgs doublet models to allow for the $\gamma\gamma$ peak. In short, the $S$ couples not only to $ZZ$, but also to $ZZ$. The $\gamma\gamma$ resonance implies new strong dynamics around 500 GeV. Our results are similar to work done by Ellis and Raza.

Title: Spin-3/2? A KK Graviton in Large N QCDAuthors: N. DeyComments: 35 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this article, we address the intriguing diphoton anomaly at run 2 and the core-cusp problem. Therefore, we scrutinize the $\gamma\gamma$ anomaly in SU(5). The flavor symmetry stabilizes the mass of the $X$. Neutral fermions at 300 GeV should be observed soon. Our results are similar to work done by Harigaya.

Title: A New Take on 2HDMs Inspired by the $\gamma\gamma$ ExcessComments: v3: added refsSubjects: High Energy Physics - Phenomenology (hep-ph)
In this paper, we look at the very recent diphoton resonance at run 2. Consequently, we study the $\gamma\gamma$ resonance in little Higgs. A corollary of this model is that it explains natural inflation. Therefore, assuming the $\gamma\gamma$ resonance is real, we predict that new gauge interactions should be at 800 GeV. More data is likely to confirm this simple framework.
