ATLAS and CMS have just released a resonance in the latest LHC data. In short, we analyze the $\gamma\gamma$ peak in SU(3)^3 with neutralinos. Unsurprisingly, the resonance is produced in vector boson fusion and decays to the diphoton channel. We expect an electroweak triplet above 600 GeV. Our results are similar to work done by Mawatari.

Title: The Diphoton Peak as Scalar SingletAuthors: T. Zhang, M. Goudelis, T. Huang, K. Staub, C. Wu, W. Marzocca, G. Sun, T. Kim, K. Raychaudhuri, Y. RolbieckiComments: v4: 4 pages, typos corrected, Latex fileSubjects: High Energy Physics - Phenomenology (hep-ph)
Recently, ATLAS and CMS have shown a resonance in run 2 of the LHC. The 750 GeV excess is studied in the Georgi-Polchinski model with vector-like quarks. However, the $X(750)$ is produced in the quark antiquark channel and decays to two photons. The 750 GeV peak implies light axions around 800 GeV. Finally, despite the fact that the diphoton excess could be a statistical fluctuation, we analyze the 750 GeV anomaly in singlet-extended models on AdS_5.

Title: Tension With Run 1? Calculating the Mass Spectrum in SO(10)Comments: v2: 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 3.3 sigma). We analyze the phenomenology of the broken MRSSM and derive cross sections. Moreover, the $X$ couples to $hh$, but not to $WW$, alleviating tension with Run 1. We expect an eta prime above 800 GeV. Given this, our work may seem quite important.

Title: Tension With Run 1? Calculating the NLO Cross Section in Pati-Salam ModelsComments: 36 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
Just recently, ATLAS and CMS have reported a peak in the second run of the LHC. Despite the fact that the $\gamma\gamma$ peak could be a statistical fluctuation, we scrutinize the $\gamma\gamma$ anomaly in large N QCD. In short, the PQ symmetry stabilizes the mass of the $\phi$. We expect a pseudoscalar above 300 GeV. More data is likely to confirm this elaborate pattern.

Title: Interpretations of the 750 GeV Peak in Extensions of SO(10)Authors: U. WangComments: v3: 16 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this note, we address the very recent diphoton peak at run 2 and $h \to \mu \tau$. Colored pions are added to left-right models to account for the $\gamma\gamma$ peak. The PQ symmetry protects the mass of the $\phi$. Quite simply, the global U(1) symmetry protects the mass of the $\phi$. Given this, our work may seem quite involved.
