Title: A New Look at Flipped SU(5) Models Inspired by the Diphoton Resonance

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 Problem
Comments: 3 pages, JHEP style, BibTeX, 21 figures
Subjects: 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.

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 Resonance
Comments: 26 pages
Subjects: 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)

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.
