Title: Interpretations of the 750 GeV Excess in Little HiggsComments: 13 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
A few months ago, ATLAS and CMS have released an excess in the second run of the LHC. Remarkably, we consider the phenomenology of GUT models and analyze flavor observables. The resonance couples to $b\bar{b}$, but not to $ZZ$, alleviating tension with Run 1. Quite simply, charge 8/3 quarks at 800 GeV should be observed soon. We believe this is indicative of a pretty pattern.

Title: The 750 GeV Anomaly as a Color SextetAuthors: Q. AustriComments: 14 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this letter, we discuss the very recent diphoton anomaly at run 2. Unfortunately, the phenomenology of the NMSSM is analyzed and we compute mass ratios. Quite simply, the global U(1) symmetry protects the mass of the $S$, but not the Higgs. We expect a heavy pion above 500 GeV. Our results are similar to work done by Sadhukhan and Mandal.

Title: On the $\gamma\gamma$ AnomalyAuthors: Z. FichetComments: v4: updated figure 2, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph)
In this letter, we talk about the recent diphoton peak at run 2. Moreover, we analyze the phenomenology of 2HDMs and evaluate deviations to Higgs couplings. The flavor symmetry protects the mass of the $X$, but not the Higgs. In short, charge 2/3 quarks at 500 GeV should be observed soon. Curiously, there is much to be done.

Title: A New Look at Seesaw Models Inspired by the 750 GeV ExcessAuthors: Z. Dutta, K. Strumia, C. Chiang, H. Tesi, E. Cao, B. Sengupta, M. Cao, K. Sun, J. Kuo, N. CaoComments: 14 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In this article, we talk about the intriguing diphoton peak at run 2 (at 4.6 sigma). Unsurprisingly, even though the diphoton excess could be a statistical fluctuation, the phenomenology of the MSSM is considered and we calculate deviations to Higgs couplings. Fortunately, the shift symmetry stabilizes the mass of the $S$. Assuming the $\gamma\gamma$ anomaly is real, we predict that neutral fermions should be at 600 GeV. More data should reveal the nature of the $\gamma\gamma$ peak.

Title: Interpretations of the $\gamma\gamma$ Excess in Extensions of TechnicolorAuthors: U. ChiangComments: v4: updated figure 3, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph)
In this note, we discuss the intriguing diphoton peak at run 2 and the core-cusp problem. Interestingly, we analyze the 750 GeV peak in folded SUSY with light axions. The global U(1) symmetry protects the mass of the $\eta$, but not the Higgs. Actually, heavy scalars at 800 GeV should be observed soon. Finally, we consider the phenomenology of GUT models and calculate cross sections.
