Title: The Diphoton Excess From Split SUSY ModelsComments: 43 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just presented an anomaly in the 13 TeV data. However, the phenomenology of the NMSSM is scrutinized and we calculate decay widths. The $\phi$ is produced in the quark antiquark channel and decays to two photons. Assuming the 750 GeV peak is real, we predict that vector-like quarks should be at 900 GeV. Our results are similar to work done by Hall and Ren.

Title: Interpretations of the Diphoton Excess in Extensions of $\lambda$SUSYAuthors: G. Gogoladze, U. Patra, D. Wang, H. Harland-Lang, C. Yanagida, P. Maxin, E. Bernon, J. Strumia, U. Wang, Z. GoudelisComments: 29 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this note, we address the intriguing diphoton peak at run 2. Surprisingly, vector-like quarks are added to flipped SU(5) models to account for the 750 GeV excess. A downside of this model is that it encapsulates all the relevant physics. Interestingly, we expect a pseudoscalar above 600 GeV. We believe this is indicative of an elaborate pattern.

Title: A New Look at Gauge-extended Models Inspired by the $\gamma\gamma$ ExcessAuthors: Q. HamadaComments: v2: updated figure 1, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph)
In this note, we discuss the very recent diphoton excess at run 2 and $B \to D \tau \nu$. We scrutinize the phenomenology of large N QCD and analyze production rates. The discrete symmetry protects the mass of the resonance. Remarkably, the $X$ couples to $b\bar{b}$, but not to $Z\gamma$, alleviating tension with Run 1. Quite simply, there is much to be done.

Title: Interpretations of the $\gamma\gamma$ Anomaly in SU(3)^3Comments: 20 pages, Latex file, reference added, typos correctedSubjects: High Energy Physics - Phenomenology (hep-ph)
In this article, we look at the intriguing diphoton anomaly at run 2 (at 2.8 sigma). In short, conformal dynamics are added to AdS/CFT to compensate for the $\gamma\gamma$ anomaly. Therefore, the $\phi$ is produced in vector boson fusion and decays to $\gamma\gamma$. Colored pions at 700 GeV should be observed soon. More data should reveal the nature of the $\gamma\gamma$ peak.

Title: The 750 GeV Anomaly From 2HDMsAuthors: F. WangComments: 2 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this paper, we discuss the very recent diphoton excess at run 2. Unsurprisingly, the diphoton excess is analyzed in E6 with new strong dynamics. Fortunately, the $\phi$ couples to $ZZ$, but not to $Z\gamma$, worsening tension with Run 1. We expect a pion above 300 GeV. Finally, we scrutinize the 750 GeV anomaly in Georgi-Machacek models on warped metric.
