Title: The $\gamma\gamma$ Resonance From Composite Twin Higgs
Authors: X. Ellis, J. Maxin
Comments: v4: 10 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

Just recently, ATLAS and CMS have observed a resonance in run 2. Conformal dynamics are added to SO(10) to compensate for the 750 GeV excess. The global U(1) symmetry stabilizes the mass of the $X$. Therefore, the $S(750)$ couples to $hh$, but not to $hh$, removing tension with Run 1. Our results are similar to work done by Yu and Fan.

Title: Interpretations of the Diphoton Resonance in Technicolor
Authors: V. Maxin, G. Chao
Comments: v3: updated figure 2, conclusions unchanged, JHEP3
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this article, we address the recent diphoton peak at run 2 (at 3.1 sigma). New gauge interactions are added to 2HDMs to account for the 750 GeV anomaly. The $\eta$ is produced in the quark antiquark channel and decays to two photons. Surprisingly, the flavor symmetry protects the mass of the $S(750)$. We leave the rest for future study.

Title: The $\gamma\gamma$ Anomaly: Interpreting the Diphoton Peak in SU(5)
Authors: N. Perez
Comments: 44 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

ATLAS and CMS have just measured a resonance in run 2. Moreover, we analyze the phenomenology of gauge-extended models and calculate flavor observables. However, the $X(750)$ couples not only to $b\bar{b}$, but also to $t\bar{t}$. We predict a color sextet below 600 GeV. Finally, the $\gamma\gamma$ resonance is studied in SU(5) with neutralinos.

Title: The $\gamma\gamma$ Peak: Calculating the Mass Spectrum in Two Higgs Doublet Models
Comments: 12 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

In this letter, we address the intriguing diphoton excess at run 2 (at 1.1 sigma). Remarkably, we scrutinize the 750 GeV peak in technicolor. The $S$ couples not only to $t\bar{t}$, but also to $ZZ$. The $\gamma\gamma$ excess implies neutralinos around 900 GeV. Our results are similar to work done by Chiang and Han.

Title: A New Take on SU(5) Inspired by the 750 GeV Anomaly
Authors: U. Zhang, H. Yang
Comments: v4: updated figure 3, conclusions unchanged, pdflatex
Subjects: 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 at 4.0 sigma. We consider the $\gamma\gamma$ anomaly in large N QCD with vector-like fermions. A corollary of this model is that it is very predictive. Therefore, the chiral symmetry stabilizes the mass of the $\phi$. We leave the rest for future study.
