Title: On the Diphoton ExcessComments: v2: 4 pages, added refs, published in PRDSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this article, we discuss the intriguing diphoton anomaly at run 2. Remarkably, although the diphoton resonance could be a statistical fluctuation, we analyze the phenomenology of technicolor and evaluate branching ratios. Consequently, the $S(750)$ couples not only to $Z\gamma$, but also to $t\bar{t}$. The diphoton peak implies vector-like quarks around 800 GeV. We leave the rest for future study.

Title: Is It Wide? Interpreting the $\gamma\gamma$ Excess in Seesaw ModelsComments: v2: 4 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this note, we discuss the recent diphoton resonance at run 2 and $h \to \mu \tau$. Actually, vector-like quarks are added to SU(5) to account for the $\gamma\gamma$ anomaly. Therefore, the $\phi$ couples to $WW$, but not to $t\bar{t}$, removing tension with Run 1. The $\gamma\gamma$ excess implies heavy scalars around 500 GeV. Our results are similar to work done by Han.

Title: The Diphoton Excess: Calculating the NLO Cross Section in Seesaw ModelsComments: 39 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just shown an excess in run 2 of the LHC. Despite the fact that the 750 GeV resonance could be a statistical fluctuation, we scrutinize the 750 GeV peak in two Higgs doublet models. The $X(750)$ is produced in gluon fusion and decays to a pair of photons. Unsurprisingly, the R symmetry protects the mass of the resonance, but not the Higgs. More data is likely to confirm this elegant theorem.

Title: A New Take on the Polchinski-Heisenberg Model Inspired by the $\gamma\gamma$ ExcessComments: 18 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
ATLAS and CMS have just presented an excess in the second run of the LHC. Thus, we study the diphoton resonance in technicolor with new gauge interactions. A corollary of this model is that it cannot account for the galactic center excess. Actually, we predict a color sextet below 900 GeV. Given this, our work may seem quite unsurprising.

Title: A New Look at the Bohr-Polchinski Model Inspired by the $\gamma\gamma$ AnomalyComments: v3: added refsSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just presented an anomaly in the second run of the LHC at 4.0 sigma. We study the 750 GeV excess in two Higgs doublet models. Interestingly, a downside of this model is that $WW$ and $WW$ are predicted to be small. We predict an eta prime below 300 GeV. We leave the rest for future study.
