Title: How Wide? Calculating the NLO Cross Section in Pati-Salam ModelsComments: v4: updated figure 4, conclusions unchanged, minor correctionsSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this article, we address the very recent diphoton resonance at run 2 and the 2 TeV resonance. Quite simply, we analyze the phenomenology of large N QCD and derive branching ratios. Moreover, the $\eta$ is produced in elastic scattering and decays to two photons. The diphoton peak implies new strong dynamics around 900 GeV. More data should reveal the nature of the $\gamma\gamma$ anomaly.

Title: The 750 GeV Excess From Composite Twin HiggsComments: v4: added refsSubjects: High Energy Physics - Phenomenology (hep-ph)
Recently, ATLAS and CMS have released an anomaly in the second run of the LHC. We study the phenomenology of GUT models and compute cross sections. The chiral symmetry stabilizes the mass of the $\phi$. Therefore, vector-like quarks are required at 700 GeV. More data is likely to confirm this shocking edifice.

Title: Interpretations of the $\gamma\gamma$ Peak in the MSSMComments: v2: added refsSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this paper, we discuss the very recent diphoton peak at run 2 and natural inflation. However, the $\gamma\gamma$ excess is considered in twin Higgs with heavy scalars. The $X(750)$ couples to $hh$, but not to $ZZ$, worsening tension with Run 1. Assuming the $\gamma\gamma$ excess is real, we predict that conformal dynamics should be at 300 GeV. Given this, our work may seem quite charming.

Title: Interpretations of the Diphoton Peak in Extensions of 2HDMsComments: 29 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just measured an excess in run 2 of the LHC at 2.2 sigma. Interestingly, we analyze the diphoton resonance in fat Higgs. The PQ symmetry protects the mass of the $X$. We expect scalar singlet above 700 GeV. Finally, the 750 GeV anomaly is analyzed in AdS/CFT with neutralinos.

Title: The Diphoton Resonance From SO(10)Comments: v3: updated figure 1, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just reported an excess in the latest LHC data at 2.2 sigma. Curiously, we analyze the phenomenology of Seesaw models and compute flavor observables. The conformal symmetry stabilizes the mass of the $X(750)$. Surprisingly, assuming the diphoton resonance is real, we predict that new strong dynamics should be at 600 GeV. Given this, our work may seem quite simple.
