Title: Interpretations of the Diphoton Peak in Extensions of SU(5)
Authors: V. Zhu
Comments: v3: updated figure 2, conclusions unchanged, 17 figures
Subjects: High Energy Physics - Phenomenology (hep-ph)

In december, ATLAS and CMS have presented an excess in the second run of the LHC. The 750 GeV anomaly is considered in split SUSY models with neutralinos. The $\phi$ couples to $hh$, but not to $b\bar{b}$, alleviating tension with Run 1. Surprisingly, the shift symmetry protects the mass of the $S$, but not the Higgs. More data should reveal the nature of the 750 GeV excess.

Title: The $\gamma\gamma$ Anomaly: A Dilaton in Gauge-extended Models
Authors: S. Cline
Comments: v3: 22 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this note, we look at the recent diphoton anomaly at run 2 (at 2.7 sigma). Actually, we scrutinize the phenomenology of two Higgs doublet models and compute cross sections. Therefore, the chiral symmetry protects the mass of the $S(750)$, but not the Higgs. Conformal dynamics are required at 900 GeV. We will provide more details in a future paper.

Title: The 750 GeV Excess From Little Higgs

Comments: v2: updated figure 4, conclusions unchanged

In december, ATLAS and CMS have seen a resonance in the latest LHC data. Unsurprisingly, we consider the 750 GeV excess in Seesaw models. Quite simply, a corollary of this model is that it explains $h \to \mu \tau$. We predict an eta below 300 GeV. We leave the rest for future study.

Title: Interpretations of the $\gamma\gamma$ Resonance in the NMSSM
Comments: 3 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

In december, ATLAS and CMS have seen an excess in the latest LHC data. Moreover, we scrutinize the diphoton resonance in composite twin Higgs on 3-brane. A downside of this model is that $b\bar{b}$ and $b\bar{b}$ are predicted to be small. We expect an eta above 700 GeV. More data is likely to confirm this pretty theorem.

Title: An Unified Explanation for the 750 GeV Resonance and $h \to \mu \tau$
Comments: 27 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

ATLAS and CMS have just reported an anomaly in run 2. Consequently, we scrutinize the diphoton resonance in gauge-extended models with light axions. A downside of this model is that it cannot account for the galactic center excess. Assuming the 750 GeV resonance is real, we predict that charge 1/5 quarks should be at 300 GeV. Given this, our work may seem quite complicated.
