Title: The Diphoton Anomaly as a Color SextetAuthors: A. WuComments: v3: 19 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this paper, we discuss the intriguing diphoton anomaly at run 2. Remarkably, we scrutinize the phenomenology of technicolor and evaluate deviations to Higgs couplings. Actually, the $S(750)$ couples not only to $hh$, but also to $hh$. We predict a pion below 700 GeV. More data is likely to confirm this profound structure.

Title: Relating the Diphoton Excess and $h \to \mu \tau$Comments: v2: 26 pages, published in PRDSubjects: High Energy Physics - Phenomenology (hep-ph)
In this letter, we discuss the intriguing diphoton excess at run 2 (at 3.9 sigma). We analyze the $\gamma\gamma$ peak in the broken MRSSM with exotic fermions. The $\eta$ is produced in gluon fusion and decays to $\gamma\gamma$. Actually, colored pions at 800 GeV should be observed soon. More data is likely to confirm this pretty pattern.

Title: Interpretations of the $\gamma\gamma$ Anomaly in Gauge-extended ModelsComments: 46 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this article, we talk about the intriguing diphoton peak at run 2. In short, neutralinos are added to left-right models to explain the 750 GeV anomaly. However, the PQ symmetry protects the mass of the $S(750)$. We expect a dilaton above 300 GeV. Our results are similar to work done by Yang and Strumia.

Title: The $\gamma\gamma$ Excess: Calculating the Mass Spectrum in Singlet-extended ModelsComments: 37 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
ATLAS and CMS have just presented an anomaly in run 2 of the LHC. Thus, while the 750 GeV anomaly could be a statistical fluctuation, we consider the diphoton anomaly in Georgi-Machacek models on a D3-brane. The resonance couples not only to $b\bar{b}$, but also to $ZZ$. Fortunately, conformal dynamics at 300 GeV should be observed soon. We leave the rest for future study.

Title: On the $\gamma\gamma$ PeakComments: 30 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
Just recently, ATLAS and CMS have observed an anomaly in the second run of the LHC. Remarkably, the 750 GeV resonance is considered in flipped SU(5) models with new gauge interactions. The global U(1) symmetry protects the mass of the $S$. We expect scalar singlet above 500 GeV. Finally, we study the diphoton peak in Seesaw models.
