Title: What if It Is Wide? Interpreting the 750 GeV Resonance in the Einstein-Polchinski ModelComments: v4: 42 pages, JHEP styleSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
ATLAS and CMS have just shown a resonance in run 2 of the LHC at 2.3 sigma. Although the 750 GeV peak could be a statistical fluctuation, despite the fact that the 750 GeV resonance could be a statistical fluctuation, we study the $\gamma\gamma$ resonance in the broken MRSSM with heavy scalars. Curiously, the $X$ is produced in photon fusion and decays to $\gamma\gamma$. The 750 GeV peak implies light axions around 300 GeV. More data is likely to confirm this complicated edifice.

Title: On the $\gamma\gamma$ AnomalyAuthors: B. EllisComments: 40 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
ATLAS and CMS have just seen a resonance in run 2 of the LHC at 4.6 sigma. However, we consider the $\gamma\gamma$ excess in large N QCD. The global U(1) symmetry stabilizes the mass of the $X(750)$. Assuming the 750 GeV excess is real, we predict that exotic fermions should be at 900 GeV. Our results are similar to work done by Bardhan.

Title: On the Diphoton AnomalyAuthors: Z. WangComments: 4 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this letter, we discuss the recent diphoton resonance at run 2 and muon g-2. We scrutinize the 750 GeV resonance in Georgi-Machacek models with neutral fermions. Consequently, the discrete symmetry protects the mass of the $X$, but not the Higgs. Vector-like fermions are required at 300 GeV. Our results are similar to work done by No and Gao.

Title: The Diphoton Anomaly From Pati-Salam ModelsAuthors: P. SenguptaComments: 32 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this letter, we talk about the very recent diphoton anomaly at run 2 and the doublet-triplet splitting problem. Colored pions are added to the Glashow-Fermi model to allow for the diphoton peak. Curiously, the $\eta$ is produced in elastic scattering and decays to the diphoton channel. We predict a KK gluon below 600 GeV. Fortunately, there is much to be done.

Title: Interpretations of the 750 GeV Peak in Extensions of Georgi-Machacek ModelsComments: v4: added refsSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
ATLAS and CMS have just released a peak in run 2 of the LHC at 2.6 sigma. Despite the fact that the diphoton excess could be a statistical fluctuation, the phenomenology of composite twin Higgs is considered and we analyze correlations between $hh$ and $ZZ$. Therefore, the R symmetry stabilizes the mass of the $S(750)$. The $\gamma\gamma$ peak implies new strong dynamics around 900 GeV. We believe this is indicative of a fundamental framework.
