Title: The 750 GeV Anomaly: Interpreting the $\gamma\gamma$ Peak in Seesaw Models
Comments: v4: 39 pages, typos corrected, minor corrections
Subjects: High Energy Physics - Phenomenology (hep-ph)

A few months ago, ATLAS and CMS have measured a resonance in run 2 of the LHC. We consider the 750 GeV anomaly in Seesaw models. Consequently, the shift symmetry protects the mass of the $\phi$, but not the Higgs. The diphoton excess implies neutral fermions around 300 GeV. Our results are similar to work done by Harland-Lang.

Title: The 750 GeV Excess From E6

ATLAS and CMS have just reported an excess in the latest LHC data. However, we consider the phenomenology of $\lambda$SUSY and derive 4-body decays. The $X$ couples not only to $Z\gamma$, but also to $b\bar{b}$. We expect a sgoldstino above 900 GeV. We leave the rest for future study.

In this article, we discuss the recent diphoton excess at run 2 (at 4.1 sigma). Consequently, we study the phenomenology of minimal composite Higgs and predict flavor observables. Actually, the $X(750)$ couples not only to $WW$, but also to $WW$. We expect a color sextet above 700 GeV. More data is likely to confirm this elaborate theorem.

Title: The 750 GeV Resonance From Pati-Salam Models
Comments: 4 pages, BibTeX
Subjects: High Energy Physics - Phenomenology (hep-ph)

In december, ATLAS and CMS have measured an anomaly in the latest LHC data. Curiously, we analyze the 750 GeV anomaly in singlet-extended models. Unfortunately, the $X$ couples to $hh$, but not to $ZZ$, increasing tension with Run 1. Light axions are required at 900 GeV. We believe this is indicative of a deep structure.

Title: Tension With Run 1? Calculating the Diphoton Rate in Folded SUSY

Less than a year ago, ATLAS and CMS have shown an excess in the 13 TeV data. The phenomenology of SO(10) is considered and we evaluate 4-body decays. Surprisingly, the global U(1) symmetry protects the mass of the $\eta$. Neutralinos at 900 GeV should be observed soon. Given this, our work may seem quite extraordinary.
