Title: Interpretations of the Diphoton Excess in Extensions of AdS/CFT
Authors: L. Kats, N. Nomura
Comments: 2 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this article, we look at the intriguing diphoton excess at run 2 and muon g-2. Remarkably, neutralinos are added to Georgi-Machacek models to compensate for the diphoton resonance. The $S(750)$ couples not only to $WW$, but also to $hh$. Fortunately, we expect an axion above 300 GeV. We will provide more details in a future paper.

In this paper, we look at the very recent diphoton peak at run 2 and $h \to \mu \tau$. We analyze the diphoton anomaly in the NMSSM on a D3-brane. A feature of this model is that it explains $h \to \mu \tau$. Therefore, we predict an axion below 600 GeV. Given this, our work may seem quite deep.

Title: Interpretations of the $\gamma\gamma$ Resonance in Left-right Models
Comments: v2: updated figure 1, conclusions unchanged
Subjects: High Energy Physics - Phenomenology (hep-ph)

ATLAS and CMS have just observed an excess in the 13 TeV data. Therefore, we analyze the diphoton resonance in composite models with neutralinos. The $X(750)$ couples not only to $ZZ$, but also to $b\bar{b}$. Assuming the diphoton peak is real, we predict that heavy scalars should be at 700 GeV. We leave the rest for future study.

Title: A New Look at SU(5) Inspired by the 750 GeV Anomaly
Comments: v3: updated figure 1, conclusions unchanged
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

In this note, we discuss the intriguing diphoton excess at run 2 and the galactic center excess. The phenomenology of SU(5) is scrutinized and we analyze branching ratios. The $\phi$ is produced in inelastic scattering and decays to a pair of photons. In short, colored pions at 400 GeV should be observed soon. We believe this is indicative of a startling truth.

Title: The $\gamma\gamma$ Resonance From Split SUSY Models
Comments: v4: added refs
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

ATLAS and CMS have just shown a peak in run 2 of the LHC at 4.9 sigma. We analyze the 750 GeV excess in technicolor on 3-brane. The conformal symmetry protects the mass of the resonance, but not the Higgs. Actually, the $\phi$ couples not only to $t\bar{t}$, but also to $Z\gamma$. Finally, while the diphoton peak could be a statistical fluctuation, the $\gamma\gamma$ excess is considered in AdS/CFT with new gauge interactions.
