Title: Tension With Run 1? A Color Sextet in E6

Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

In this note, we discuss the recent diphoton anomaly at run 2 (at 1.1 sigma). We study the 750 GeV resonance in the MSSM on a D3-brane. The chiral symmetry protects the mass of the resonance, but not the Higgs. Surprisingly, we predict an eta below 600 GeV. We will provide more details in a future paper.

Title: On the 750 GeV Excess

Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

In this letter, we address the intriguing diphoton resonance at run 2. Quite simply, the diphoton anomaly is analyzed in the Polchinski-Feynman model with light axions. The $S(750)$ couples to $b\bar{b}$, but not to $ZZ$, reducing tension with Run 1. We predict an eta below 800 GeV. Finally, neutral fermions are added to AdS/CFT to compensate for the 750 GeV anomaly.

Title: The Diphoton Resonance as a KK Graviton

In this article, we look at the recent diphoton peak at run 2 (at 4.0 sigma). We analyze the phenomenology of Seesaw models and derive flavor observables. The $X$ is produced in elastic scattering and decays to a pair of photons. However, the $\phi$ couples not only to $b\bar{b}$, but also to $Z\gamma$. Given this, our work may seem quite charming.

Title: The Diphoton Resonance From SU(3)^3

ATLAS and CMS have just released an excess in the second run of the LHC at 4.8 sigma. Surprisingly, even though the $\gamma\gamma$ excess could be a statistical fluctuation, the 750 GeV peak is considered in composite twin Higgs with light axions. The PQ symmetry protects the mass of the resonance, but not the Higgs. We predict a KK gluon below 400 GeV. Our results are similar to work done by Bertuzzo and Ren.

In this note, we look at the very recent diphoton resonance at run 2 (at 1.4 sigma). We analyze the 750 GeV peak in fat Higgs. A feature of this model is that it is very predictive. Quite simply, the $S$ couples to $b\bar{b}$, but not to $b\bar{b}$, removing tension with Run 1. Our results are similar to work done by Gao and Hamada.
