Title: Relating the $\gamma\gamma$ Resonance and the 2 TeV ResonanceComments: v2: added refsSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In this note, we look at the intriguing diphoton anomaly at run 2 and the galactic center excess. Remarkably, we analyze the $\gamma\gamma$ excess in twin Higgs. The $\phi$ couples to $hh$, but not to $hh$, removing tension with Run 1. Curiously, we expect a pseudoscalar above 800 GeV. We will provide more details in a future paper.

Title: The $\gamma\gamma$ Peak From Georgi-Machacek ModelsComments: v2: added refs, based on a talk given on Fermi's 20th birthdaySubjects: High Energy Physics - Phenomenology (hep-ph)
Recently, ATLAS and CMS have measured an excess in the latest LHC data. Therefore, the 750 GeV anomaly is analyzed in technicolor with heavy scalars. The global U(1) symmetry protects the mass of the $X(750)$, but not the Higgs. We expect a heavy pion above 900 GeV. We leave the rest for future study.

Title: Tension With Run 1? Interpretations in the NMSSMComments: v2: updated figure 1, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this note, we discuss the intriguing diphoton excess at run 2 and the doublet-triplet splitting problem. Surprisingly, despite the fact that the $\gamma\gamma$ excess could be a statistical fluctuation, we analyze the phenomenology of the broken MRSSM and derive flavor observables. Interestingly, the conformal symmetry protects the mass of the resonance. We expect a sgoldstino above 600 GeV. Our results are similar to work done by Omura.

Title: The Diphoton Anomaly From Seesaw ModelsAuthors: M. Han, N. Staub, B. Nomura, Y. Yu, R. Maxin, E. Hall, G. Sanz, O. Raza, F. Buttazzo, L. LiComments: v2: 31 pages, added refsSubjects: High Energy Physics - Phenomenology (hep-ph)
In december, ATLAS and CMS have shown an excess in the 13 TeV data. We scrutinize the 750 GeV peak in large N QCD on a lattice. Unsurprisingly, the chiral symmetry protects the mass of the $X$. Neutral fermions at 600 GeV should be observed soon. Finally, we study the phenomenology of the Sundrum-Einstein model and analyze anomalous dimensions.

Title: Spin-3/2? Interpretations in Minimal Composite HiggsAuthors: V. SantiagoComments: 32 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
ATLAS and CMS have just reported an anomaly in the 13 TeV data. Thus, colored pions are added to 2HDMs to allow for the diphoton peak. The $S$ couples to $hh$, but not to $WW$, reducing tension with Run 1. Heavy scalars are required at 300 GeV. Our results are similar to work done by Li.
