Title: The Diphoton Anomaly: Calculating the Mass Spectrum in the MSSMAuthors: W. TesiComments: 40 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
Just recently, ATLAS and CMS have released a peak in the 13 TeV data. Colored pions are added to gauge-extended models to explain the 750 GeV peak. Surprisingly, the discrete symmetry stabilizes the mass of the $\eta$. The diphoton resonance implies light axions around 500 GeV. Given this, our work may seem quite arresting.

Title: Explaining the Diphoton Resonance and the Strong CP ProblemAuthors: I. Mawatari, F. Yu, R. Chao, P. Royon, X. Gersdorff, C. Goudelis, T. Zhang, D. Ellis, M. Wang, U. HanComments: v2: 33 pages, added refsSubjects: High Energy Physics - Phenomenology (hep-ph)
In this letter, we address the recent diphoton excess at run 2 (at 1.8 sigma). We consider the phenomenology of the Glashow-Feynman model and derive deviations to Higgs couplings. In short, the chiral symmetry protects the mass of the $S(750)$. We predict a pion below 300 GeV. Given this, our work may seem quite remarkable.

Title: A New Look at the Coleman-Polchinski Model Inspired by the $\gamma\gamma$ ResonanceComments: v4: 40 pages, added refsSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
ATLAS and CMS have just presented a peak in run 2 of the LHC. We scrutinize the $\gamma\gamma$ peak in SU(5) with light axions. Quite simply, a drawback of this model is that it cannot account for the strong CP problem. New strong dynamics at 400 GeV should be observed soon. We leave the rest for future study.

Title: Interpretations of the $\gamma\gamma$ Excess in Extensions of the Broken MRSSMAuthors: Z. ZhangComments: v4: 13 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this letter, we talk about the very recent diphoton excess at run 2 (at 1.4 sigma). Unfortunately, we analyze the diphoton peak in E6. The $X(750)$ is produced in elastic scattering and decays to a pair of photons. New gauge interactions at 700 GeV should be observed soon. More data is likely to confirm this profound law.

Title: A New Take on Twin Higgs Inspired by the $\gamma\gamma$ ResonanceAuthors: S. Chao, W. Park, R. Han, W. Staub, B. Chao, N. Nomura, P. Park, F. Dev, Q. Nomura, I. YanagidaComments: v4: updated figure 3, conclusions unchanged, minor correctionsSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
Just recently, ATLAS and CMS have seen a peak in the second run of the LHC. Fortunately, the 750 GeV anomaly is considered in flipped SU(5) models with vector-like quarks. The $X$ is produced in the quark antiquark channel and decays to a pair of photons. We predict a KK graviton below 800 GeV. More data should reveal the nature of the diphoton anomaly.
