Title: A New Look at Two Higgs Doublet Models Inspired by the $\gamma\gamma$ ResonanceComments: 48 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just seen an anomaly in run 2 at 4.2 sigma. New strong dynamics are added to left-right models to compensate for the $\gamma\gamma$ resonance. Unfortunately, the global U(1) symmetry stabilizes the mass of the $\eta$. Neutral fermions at 400 GeV should be observed soon. Given this, our work may seem quite arresting.

Title: The 750 GeV Resonance From Flipped SU(5) ModelsAuthors: G. HanComments: v3: updated figure 2, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph)
Recently, ATLAS and CMS have seen an anomaly in run 2 of the LHC. Heavy scalars are added to $\lambda$SUSY to account for the 750 GeV anomaly. Actually, the PQ symmetry stabilizes the mass of the $X$. Exotic fermions at 600 GeV should be observed soon. More data is likely to confirm this arresting framework.

Title: The Diphoton Peak From Large N QCDComments: 23 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this article, we address the very recent diphoton resonance at run 2 and the diboson resonance. Even though the diphoton resonance could be a statistical fluctuation, vector-like fermions are added to split SUSY models to account for the $\gamma\gamma$ excess. The discrete symmetry protects the mass of the $S$. Therefore, the R symmetry protects the mass of the resonance. Unfortunately, there is much to be done.

Title: A Common Framework for the Diphoton Peak and $B \to D \tau \nu$Authors: F. KatsComments: 25 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this paper, we talk about the very recent diphoton excess at run 2 and natural inflation. While the diphoton anomaly could be a statistical fluctuation, the phenomenology of composite models is considered and we predict mass ratios. Curiously, a drawback of this model is that $b\bar{b}$ and $Z\gamma$ are predicted to be enormous. The $\gamma\gamma$ anomaly implies colored pions around 900 GeV. Given this, our work may seem quite charming.

Title: The $\gamma\gamma$ Excess From Folded SUSYComments: v4: added refs, 3 tables, 4 figuresSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In this paper, we look at the intriguing diphoton peak at run 2 (at 2.7 sigma). We consider the diphoton resonance in twin Higgs with exotic fermions. The $S(750)$ couples not only to $hh$, but also to $ZZ$. Unsurprisingly, colored pions are required at 700 GeV. We leave the rest for future study.
