Just recently, ATLAS and CMS have shown an excess in the latest LHC data. We consider the 750 GeV excess in folded SUSY with new strong dynamics. The $S(750)$ is produced in vector boson fusion and decays to a pair of photons. Quite simply, assuming the $\gamma\gamma$ anomaly is real, we predict that heavy scalars should be at 800 GeV. We leave the rest for future study.

Title: The Diphoton Excess as a Color Sextet

Subjects: High Energy Physics - Phenomenology (hep-ph)

ATLAS and CMS have just seen a peak in run 2 at 4.7 sigma. Quite simply, we analyze the 750 GeV peak in little Higgs on warped metric. The conformal symmetry protects the mass of the $S$. New gauge interactions are required at 400 GeV. Given this, our work may seem quite mysterious.

Title: A New Take on the NMSSM Inspired by the $\gamma\gamma$ Anomaly
Comments: v2: added refs
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this note, we discuss the intriguing diphoton anomaly at run 2. We study the phenomenology of composite twin Higgs and derive flavor observables. The R symmetry protects the mass of the $S$, but not the Higgs. Interestingly, a corollary of this model is that it cannot account for the core-cusp problem. Our results are similar to work done by Strumia.

Title: The 750 GeV Anomaly From Georgi-Machacek Models
Authors: L. Rolbiecki
Comments: 2 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

In this article, we look at the recent diphoton peak at run 2 (at 2.4 sigma). The phenomenology of technicolor is scrutinized and we derive anomalous dimensions. The $X(750)$ couples to $WW$, but not to $hh$, increasing tension with Run 1. Quite simply, assuming the $\gamma\gamma$ peak is real, we predict that heavy scalars should be at 400 GeV. More data is likely to confirm this pretty law.

Title: The 750 GeV Anomaly: Interpretations in Composite Models
Authors: H. Chiang
Comments: v4: 47 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

In this article, we address the intriguing diphoton anomaly at run 2 (at 3.7 sigma). We consider the $\gamma\gamma$ resonance in SO(10). Surprisingly, the flavor symmetry stabilizes the mass of the resonance. We expect an electroweak triplet above 400 GeV. Given this, our work may seem quite bewildering.
