Title: The 750 GeV Excess: A KK Gluon in Split SUSY Models

Comments: v3: updated figure 4, conclusions unchanged
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this letter, we address the very recent diphoton peak at run 2 and the diboson resonance. In short, the 750 GeV resonance is considered in flipped SU(5) models with colored pions. Fortunately, the conformal symmetry stabilizes the mass of the $\phi$. We expect an eta above 800 GeV. Our results are similar to work done by Wang and Yagyu.

Title: Tension With Run 1? Interpretations in Fat Higgs
Authors: D. Nomura
Comments: 13 pages, 4 figures
Subjects: High Energy Physics - Phenomenology (hep-ph)

ATLAS and CMS have just shown a peak in the second run of the LHC. Surprisingly, we study the phenomenology of composite twin Higgs and predict deviations to Higgs couplings. Interestingly, the $S$ couples not only to $ZZ$, but also to $Z\gamma$. Assuming the 750 GeV peak is real, we predict that neutral fermions should be at 700 GeV. More data is likely to confirm this complicated pattern.

Title: Spin-3/2? A KK Gluon in Split SUSY Models
Authors: X. Kuo
Comments: 2 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

ATLAS and CMS have just measured an excess in the latest LHC data. Quite simply, we consider the phenomenology of large N QCD and analyze 4-body decays. The global U(1) symmetry protects the mass of the $S(750)$. Therefore, the 750 GeV excess implies exotic fermions around 800 GeV. Our results are similar to work done by Dev.

Title: Interpretations of the $\gamma\gamma$ Anomaly in Gauge-extended Models
Authors: P. Ko, Y. Sanz
Comments: v2: 47 pages, added refs
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this note, we discuss the very recent diphoton peak at run 2. We scrutinize the 750 GeV resonance in E6. The $S$ couples not only to $hh$, but also to $ZZ$. In short, the resonance couples not only to $t\bar{t}$, but also to $t\bar{t}$. More data is likely to confirm this surprising truth.

Title: A New Look at $\lambda$SUSY Inspired by the Diphoton Resonance
Comments: 4 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

In this article, we talk about the very recent diphoton peak at run 2. However, the phenomenology of flipped SU(5) models is considered and we evaluate branching ratios. Remarkably, the flavor symmetry protects the mass of the $X$, but not the Higgs. Exotic fermions are required at 700 GeV. Our results are similar to work done by Kuo and Ko.
