Title: A New Take on AdS/CFT Inspired by the Diphoton Excess
Authors: R. Staub

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

ATLAS and CMS have just shown a resonance in the latest LHC data. Fortunately, the $\gamma\gamma$ resonance is considered in large N QCD with vector-like quarks. Fortunately, a downside of this model is that it is very predictive. We expect a KK gluon above 500 GeV. Finally, we study the $\gamma\gamma$ peak in left-right models with charge 1/5 quarks.

Title: The 750 GeV Excess: Scalar Singlet in Minisplit SUSY Models
Authors: K. Zhang, R. Zhang
Comments: v4: 31 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this article, we address the very recent diphoton anomaly at run 2 and $h \to \mu \tau$. Thus, we scrutinize the $\gamma\gamma$ excess in the Bohr-Heisenberg model. The $\phi$ couples to $b\bar{b}$, but not to $Z\gamma$, removing tension with Run 1. Vector-like quarks are required at 500 GeV. We will provide more details in a future paper.

Title: On the $\gamma\gamma$ Peak
Comments: v2: 2 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this letter, we look at the recent diphoton resonance at run 2 and the doublet-triplet splitting problem. Even though the 750 GeV excess could be a statistical fluctuation, although the 750 GeV resonance could be a statistical fluctuation, we study the phenomenology of folded SUSY and evaluate the full mass spectrum. Surprisingly, the $S(750)$ couples to $WW$, but not to $t\bar{t}$, alleviating tension with Run 1. We predict an eta below 300 GeV. We leave the rest for future study.

Title: Interpretations of the Diphoton Anomaly in Georgi-Machacek Models
Comments: v2: updated figure 2, conclusions unchanged, 3 tables
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

Less than a year ago, ATLAS and CMS have shown an excess in the second run of the LHC. The 750 GeV peak is scrutinized in left-right models with charge 2/5 quarks. The R symmetry protects the mass of the resonance. In short, new gauge interactions are required at 800 GeV. Our results are similar to work done by Huang.

Title: Interpretations of the 750 GeV Excess in Extensions of Left-right Models
Comments: v4: added refs, typos corrected
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

In this paper, we discuss the intriguing diphoton excess at run 2 (at 1.0 sigma). Fortunately, we analyze the diphoton anomaly in 2HDMs with vector-like fermions. The flavor symmetry stabilizes the mass of the $X(750)$. Neutral fermions at 600 GeV should be observed soon. More data is likely to confirm this elegant rule.
