Title: A New Look at Flipped SU(5) Models Inspired by the Diphoton ResonanceAuthors: L. OmuraComments: 3 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this paper, we talk about the very recent diphoton anomaly at run 2 (at 2.9 sigma). The $\gamma\gamma$ anomaly is considered in left-right models with exotic fermions. The conformal symmetry protects the mass of the resonance, but not the Higgs. Thus, the global U(1) symmetry protects the mass of the $S$. Our results are similar to work done by Yagyu.

Title: Explaining the $\gamma\gamma$ Excess and the Strong CP ProblemComments: 3 pages, JHEP style, BibTeX, 21 figuresSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just measured an anomaly in run 2. Unsurprisingly, we scrutinize the $\gamma\gamma$ excess in composite twin Higgs. However, the $\eta$ couples to $b\bar{b}$, but not to $Z\gamma$, worsening tension with Run 1. We predict scalar singlet below 500 GeV. We leave the rest for future study.

Title: On the Diphoton ResonanceComments: v3: added refs, minor correctionsSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this note, we look at the very recent diphoton resonance at run 2 and the diboson resonance. We analyze the 750 GeV peak in $\lambda$SUSY with conformal dynamics. The discrete symmetry stabilizes the mass of the $S$. Consequently, the resonance couples not only to $ZZ$, but also to $hh$. Our results are similar to work done by Zheng and Nomura.

Title: A Common Framework for the 750 GeV Peak and the 2 TeV ResonanceComments: 26 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
Recently, ATLAS and CMS have observed a peak in run 2. Moreover, we consider the 750 GeV anomaly in SU(5). Consequently, the $X(750)$ couples to $hh$, but not to $hh$, reducing tension with Run 1. New strong dynamics are required at 500 GeV. Given this, our work may seem quite perplexing.

Title: The $\gamma\gamma$ Resonance: A Color Sextet in SU(5)Comments: v2: added refs, reference addedSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In this letter, we address the intriguing diphoton excess at run 2. However, we scrutinize the $\gamma\gamma$ resonance in large N QCD with light axions. Fortunately, a corollary of this model is that it encapsulates all the relevant physics. New strong dynamics are required at 300 GeV. Given this, our work may seem quite startling.
