Title: Is It Wide? An Axino in the Sundrum-Georgi ModelComments: 36 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
A few months ago, ATLAS and CMS have shown a peak in run 2 of the LHC. Remarkably, colored pions are added to minisplit SUSY models to allow for the $\gamma\gamma$ anomaly. Fortunately, the $S(750)$ couples to $WW$, but not to $b\bar{b}$, decreasing tension with Run 1. We expect a pion above 500 GeV. More data should reveal the nature of the diphoton excess.

Title: Interpretations of the $\gamma\gamma$ Peak in Extensions of the MSSMComments: 3 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this note, we talk about the very recent diphoton resonance at run 2 and muon g-2. Interestingly, we scrutinize the diphoton anomaly in two Higgs doublet models on warped metric. Moreover, the shift symmetry protects the mass of the $\phi$. The 750 GeV resonance implies light axions around 900 GeV. More data should reveal the nature of the 750 GeV excess.

Title: Interpretations of the $\gamma\gamma$ Anomaly in Extensions of the NMSSMComments: v2: added refs, 1 tables, reference addedSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just reported a resonance in run 2 of the LHC at 1.6 sigma. Unsurprisingly, we consider the diphoton anomaly in 2HDMs. The conformal symmetry protects the mass of the $S(750)$. We predict an eta prime below 600 GeV. Our results are similar to work done by Raychaudhuri and Arun.

Title: Interpretations of the 750 GeV Peak in Left-right ModelsAuthors: I. NomuraComments: v2: 3 pages, added refs, minor corrections, typos correctedSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In this note, we look at the recent diphoton peak at run 2 (at 2.0 sigma). Unsurprisingly, while the diphoton anomaly could be a statistical fluctuation, we study the phenomenology of left-right models and compute the statistical significance. The conformal symmetry protects the mass of the $\eta$. Actually, we expect a KK gluon above 400 GeV. We will provide more details in a future paper.

Title: How Wide? An Eta in the Broken MRSSMAuthors: N. RolbieckiComments: v4: 38 pages, added refsSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In this article, we address the very recent diphoton excess at run 2 (at 4.6 sigma). Moreover, we consider the phenomenology of SU(3)^3 and evaluate the statistical significance. Fortunately, the $S(750)$ couples to $hh$, but not to $t\bar{t}$, alleviating tension with Run 1. We expect a color sextet above 600 GeV. Thus, there is much to be done.
