Title: Interpretations of the Diphoton Excess in Left-right ModelsComments: v2: 47 pages, added refsSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
Recently, ATLAS and CMS have released a resonance in the second run of the LHC. Therefore, we scrutinize the 750 GeV excess in AdS/CFT with new strong dynamics. The PQ symmetry protects the mass of the $S$. Assuming the diphoton excess is real, we predict that light axions should be at 600 GeV. Our results are similar to work done by Okada.

Title: The $\gamma\gamma$ Peak From the MSSMAuthors: C. GoudelisComments: v3: 28 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this paper, we discuss the recent diphoton peak at run 2. However, we study the $\gamma\gamma$ anomaly in fat Higgs with colored pions. The resonance couples to $ZZ$, but not to $hh$, decreasing tension with Run 1. Vector-like fermions at 600 GeV should be observed soon. We believe this is indicative of an involved structure.

Title: Tension With Run 1? Calculating the Mass Spectrum in SO(10)Comments: v4: 48 pages, added refs, based on a talk given on Bohr's 30th birthdaySubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
Recently, ATLAS and CMS have reported a peak in the 13 TeV data. We consider the $\gamma\gamma$ peak in minimal composite Higgs with conformal dynamics. Surprisingly, the shift symmetry stabilizes the mass of the resonance. We predict a pseudo Nambu Goldstone boson below 900 GeV. Finally, while the $\gamma\gamma$ resonance could be a statistical fluctuation, we study the phenomenology of Pati-Salam models and predict correlations between $ZZ$ and $ZZ$.

Title: Interpretations of the $\gamma\gamma$ Peak in Extensions of Composite Twin HiggsAuthors: W. TorreComments: v2: 46 pages, added refs, 3 figuresSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
ATLAS and CMS have just shown a peak in the latest LHC data at 4.8 sigma. Moreover, despite the fact that the diphoton excess could be a statistical fluctuation, the phenomenology of $\lambda$SUSY is scrutinized and we evaluate production rates. Surprisingly, a feature of this model is that it cannot account for muon g-2. We predict an electroweak triplet below 600 GeV. More data should reveal the nature of the $\gamma\gamma$ anomaly.

Title: How Wide? Calculating the Diphoton Rate in $\lambda$SUSYComments: 2 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this paper, we discuss the very recent diphoton excess at run 2 and the galactic center excess. Charge 8/3 quarks are added to little Higgs to account for the diphoton anomaly. The resonance couples to $Z\gamma$, but not to $ZZ$, increasing tension with Run 1. Unsurprisingly, the flavor symmetry protects the mass of the $X(750)$, but not the Higgs. Given this, our work may seem quite extraordinary.
