Title: Interpretations of the Diphoton Resonance in Split SUSY ModelsAuthors: W. BorahComments: 12 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In december, ATLAS and CMS have shown an anomaly in the 13 TeV data. Quite simply, while the $\gamma\gamma$ excess could be a statistical fluctuation, the phenomenology of Georgi-Machacek models is scrutinized and we calculate branching ratios. The $S(750)$ couples not only to $hh$, but also to $t\bar{t}$. Moreover, assuming the $\gamma\gamma$ excess is real, we predict that light axions should be at 900 GeV. Our results are similar to work done by Sanz and Ryskin.

Title: The $\gamma\gamma$ Resonance From Composite Twin HiggsComments: v2: added refsSubjects: High Energy Physics - Phenomenology (hep-ph)
In this letter, we look at the recent diphoton anomaly at run 2 and $B \to D \tau \nu$. We scrutinize the phenomenology of 2HDMs and derive branching ratios. Interestingly, the resonance couples to $Z\gamma$, but not to $ZZ$, increasing tension with Run 1. The 750 GeV excess implies exotic fermions around 900 GeV. We leave the rest for future study.

Title: A New Look at Fat Higgs Inspired by the $\gamma\gamma$ PeakComments: 37 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this letter, we talk about the very recent diphoton excess at run 2 and the galactic center excess. Surprisingly, we analyze the phenomenology of SO(10) and analyze mass ratios. Fortunately, the R symmetry protects the mass of the $X(750)$. The diphoton peak implies colored pions around 300 GeV. Finally, vector-like fermions are added to composite models to compensate for the 750 GeV resonance.

Title: Interpretations of the Diphoton Peak in Extensions of Fat HiggsComments: v3: 3 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In this paper, we look at the recent diphoton resonance at run 2. Fortunately, the diphoton anomaly is considered in composite models with heavy scalars. The $S(750)$ couples to $Z\gamma$, but not to $hh$, removing tension with Run 1. Actually, the 750 GeV resonance implies vector-like quarks around 300 GeV. Our results are similar to work done by Austri.

Title: The $\gamma\gamma$ Resonance: Interpreting the $\gamma\gamma$ Peak in 2HDMsAuthors: B. Sanz, S. Okada, J. Yanagida, C. Strassler, G. Ko, T. Aydemir, D. Yu, X. Sadhukhan, E. Li, A. GoudelisComments: 47 pages, published in PRDSubjects: High Energy Physics - Phenomenology (hep-ph)
Less than a year ago, ATLAS and CMS have measured a resonance in the 13 TeV data. Neutralinos are added to left-right models to allow for the $\gamma\gamma$ peak. Interestingly, a drawback of this model is that it is very predictive. The $\gamma\gamma$ anomaly implies vector-like fermions around 800 GeV. Thus, there is much to be done.
