Title: The $\gamma\gamma$ Anomaly as an EtaAuthors: V. Harigaya, L. Raychaudhuri, N. Franceschini, C. Jiang, Y. Chao, G. Su, F. Yanagida, P. Park, O. Yu, X. YangComments: v3: 10 pages, added refs, Latex fileSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just observed an anomaly in the second run of the LHC at 4.6 sigma. The phenomenology of Georgi-Machacek models is analyzed and we analyze production rates. Unfortunately, the $S$ couples not only to $hh$, but also to $t\bar{t}$. Colored pions at 900 GeV should be observed soon. Our results are similar to work done by Yanagida and Yu.

Title: The Diphoton Peak as Scalar SingletComments: 33 pages, reference addedSubjects: High Energy Physics - Phenomenology (hep-ph)
In this letter, we look at the very recent diphoton anomaly at run 2 (at 3.6 sigma). However, we analyze the phenomenology of 2HDMs and compute branching ratios. Interestingly, the conformal symmetry stabilizes the mass of the resonance. We predict an eta prime below 800 GeV. More data is likely to confirm this ingenious rule.

Title: A New Look at Gauge-extended Models Inspired by the Diphoton PeakComments: v2: 13 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just presented an anomaly in the latest LHC data. Actually, we consider the diphoton resonance in minisplit SUSY models. The $S(750)$ couples to $ZZ$, but not to $t\bar{t}$, removing tension with Run 1. Remarkably, we expect a dilaton above 700 GeV. More data should reveal the nature of the 750 GeV excess.

Title: Interpretations of the 750 GeV Peak in SO(10)Comments: v2: updated figure 2, conclusions unchanged, published in PRDSubjects: High Energy Physics - Phenomenology (hep-ph)
In this note, we look at the very recent diphoton anomaly at run 2 (at 1.0 sigma). Unfortunately, even though the $\gamma\gamma$ resonance could be a statistical fluctuation, the phenomenology of large N QCD is scrutinized and we compute mass ratios. Thus, the flavor symmetry protects the mass of the $\eta$. We predict a KK gluon below 700 GeV. More data is likely to confirm this important structure.

Title: The Diphoton Peak From Twin HiggsComments: 15 pages, based on a talk given on Weinberg's 10th birthdaySubjects: High Energy Physics - Phenomenology (hep-ph)
In this note, we look at the very recent diphoton excess at run 2. Curiously, we analyze the phenomenology of minisplit SUSY models and calculate the statistical significance. The $S(750)$ couples not only to $WW$, but also to $b\bar{b}$. Quite simply, neutralinos at 700 GeV should be observed soon. Our results are similar to work done by Yang.
