Title: The 750 GeV Excess From Split SUSY Models
Authors: C. Fan
Comments: v2: updated figure 2, conclusions unchanged
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this paper, we discuss the recent diphoton resonance at run 2 (at 3.9 sigma). Therefore, the diphoton excess is scrutinized in GUT models with new strong dynamics. Remarkably, the $S$ couples to $b\bar{b}$, but not to $hh$, alleviating tension with Run 1. Colored pions are required at 400 GeV. More data should reveal the nature of the diphoton excess.

Title: Relating the Diphoton Anomaly and $h \to \mu \tau$
Authors: W. Mayes
Comments: 29 pages, published in PRD, no figures
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

ATLAS and CMS have just reported a peak in run 2 at 3.6 sigma. We consider the phenomenology of Pati-Salam models and predict flavor observables. Interestingly, the chiral symmetry protects the mass of the $\eta$. Assuming the $\gamma\gamma$ excess is real, we predict that vector-like quarks should be at 700 GeV. We leave the rest for future study.

Title: Interpretations of the 750 GeV Peak in Fat Higgs
Comments: 44 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

ATLAS and CMS have just reported a peak in run 2 at 4.4 sigma. Surprisingly, we study the 750 GeV resonance in Pati-Salam models. A drawback of this model is that it explains muon g-2. Fortunately, we predict an axino below 500 GeV. Our results are similar to work done by Sadhukhan and Dutta.

Title: A New Look at SU(5) Inspired by the 750 GeV Resonance
Comments: 22 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

In this paper, we look at the recent diphoton anomaly at run 2. We scrutinize the phenomenology of GUT models and compute production rates. Fortunately, the R symmetry stabilizes the mass of the $\eta$. The $\gamma\gamma$ resonance implies new strong dynamics around 800 GeV. Our results are similar to work done by Han.

Title: Spin-2? Interpretations in the NMSSM
Comments: v3: 2 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

Just recently, ATLAS and CMS have shown an excess in run 2 of the LHC. However, we study the phenomenology of minimal composite Higgs and calculate flavor observables. Unsurprisingly, the R symmetry stabilizes the mass of the $S$. The 750 GeV excess implies colored pions around 700 GeV. Given this, our work may seem quite bewildering.
