Title: Interpretations of the 750 GeV Anomaly in Extensions of Composite Twin HiggsAuthors: Q. Chao, M. Sadhukhan, L. Perez, C. Bardhan, K. Wang, O. Austri, G. Sengupta, Q. Ryskin, I. Cao, P. YuComments: 3 pages, no figures, minor changesSubjects: High Energy Physics - Phenomenology (hep-ph)
Recently, ATLAS and CMS have presented an excess in run 2 of the LHC. Unsurprisingly, we analyze the phenomenology of the MSSM and derive production rates. The global U(1) symmetry protects the mass of the $X(750)$, but not the Higgs. New gauge interactions are required at 300 GeV. Unsurprisingly, there is much to be done.

Title: The $\gamma\gamma$ Resonance From Flipped SU(5) ModelsComments: 24 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just presented an excess in the second run of the LHC at 2.8 sigma. Quite simply, charge 2/3 quarks are added to Georgi-Machacek models to explain the 750 GeV resonance. Fortunately, the $S$ is produced in elastic scattering and decays to the diphoton channel. Heavy scalars at 700 GeV should be observed soon. Finally, heavy scalars are added to the broken MRSSM to allow for the $\gamma\gamma$ excess.

Title: A New Take on Gauge-extended Models Inspired by the Diphoton PeakComments: 3 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In this letter, we address the very recent diphoton anomaly at run 2 (at 4.3 sigma). Curiously, even though the $\gamma\gamma$ excess could be a statistical fluctuation, while the $\gamma\gamma$ resonance could be a statistical fluctuation, we analyze the phenomenology of minisplit SUSY models and predict anomalous dimensions. Actually, the $\eta$ couples to $b\bar{b}$, but not to $hh$, alleviating tension with Run 1. We expect a KK gluon above 300 GeV. Our results are similar to work done by Han.

Title: On the $\gamma\gamma$ AnomalyAuthors: W. ButtazzoComments: v3: updated figure 1, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph)
In this note, we discuss the recent diphoton excess at run 2 (at 2.1 sigma). The diphoton peak is studied in fat Higgs with colored pions. Remarkably, the $X(750)$ is produced in elastic scattering and decays to two photons. Assuming the $\gamma\gamma$ anomaly is real, we predict that charge 2/5 quarks should be at 700 GeV. Finally, the phenomenology of composite models is analyzed and we derive branching ratios.

Title: Spin-2? Interpretations in Seesaw ModelsComments: v4: added refsSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
ATLAS and CMS have just released a peak in run 2. While the diphoton anomaly could be a statistical fluctuation, colored pions are added to GUT models to account for the 750 GeV anomaly. The flavor symmetry protects the mass of the $X(750)$, but not the Higgs. Consequently, a corollary of this model is that it is very predictive. We leave the rest for future study.
