Title: A New Look at E6 Inspired by the 750 GeV Anomaly

Authors: S. Harland-Lang

Comments: v4: 17 pages

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

Less than a year ago, ATLAS and CMS have observed a resonance in the latest LHC data. Unsurprisingly, the $\gamma\gamma$ excess is studied in folded SUSY with exotic fermions. The conformal symmetry protects the mass of the $S$. Exotic fermions at 600 GeV should be observed soon. Finally, the 750 GeV peak is analyzed in the broken MRSSM with heavy scalars.

Title: The 750 GeV Peak: Interpretations in Fat Higgs

Authors: X. Huang

Comments: 17 pages, added refs

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

Less than a year ago, ATLAS and CMS have measured a resonance in run 2 of the LHC. We study the phenomenology of the NMSSM and compute decay widths. The $S$ is produced in gluon fusion and decays to two photons. Fortunately, new strong dynamics at 300 GeV should be observed soon. More data is likely to confirm this surprising truth.

Title: Interpretations of the 750 GeV Peak in Extensions of Gauge-extended Models

Authors: T. Shang, Z. Zheng

Comments: v4: updated figure 1, conclusions unchanged, BibTeX

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

ATLAS and CMS have just shown an excess in the latest LHC data. In short, we study the phenomenology of Seesaw models and compute mass ratios. The $S(750)$ couples to $b\bar{b}$, but not to $WW$, increasing tension with Run 1. Curiously, neutralinos at 300 GeV should be observed soon. Our results are similar to work done by Ghosh and Zhang.

Title: A New Take on Georgi-Machacek Models Inspired by the 750 GeV Excess

Authors: S. Yagyu, G. Kats

Comments: v4: updated figure 1, conclusions unchanged

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

In this letter, we talk about the very recent diphoton anomaly at run 2 and muon g-2. The 750 GeV excess is analyzed in composite models with new gauge interactions. A drawback of this model is that it encapsulates all the relevant physics. Surprisingly, the $X$ couples not only to $ZZ$, but also to $WW$. We leave the rest for future study.

Title: A New Take on Left-right Models Inspired by the $\gamma\gamma$ Excess

Authors: R. Orikasa

Comments: v3: 34 pages, added refs

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

In this letter, we address the intriguing diphoton peak at run 2 and the core-cusp problem. Therefore, we study the phenomenology of composite models and derive anomalous dimensions. The $\phi$ couples not only to $ZZ$, but also to $t\bar{t}$. Curiously, vector-like fermions are required at 600 GeV. We leave the rest for future study.
