Title: Spin-2? Interpretations in Georgi-Machacek Models
Authors: X. Bi
Comments: v3: 15 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

ATLAS and CMS have just measured an anomaly in the 13 TeV data. We analyze the $\gamma\gamma$ resonance in technicolor on a D3-brane. Thus, the R symmetry protects the mass of the resonance, but not the Higgs. Colored pions are required at 700 GeV. Consequently, there is much to be done.

Title: The $\gamma\gamma$ Anomaly as an Eta Prime
Authors: N. Park
Comments: v2: updated figure 2, conclusions unchanged, 3 tables
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this paper, we discuss the recent diphoton resonance at run 2 (at 3.5 sigma). We study the diphoton peak in 2HDMs with neutral fermions. The $\eta$ couples not only to $Z\gamma$, but also to $b\bar{b}$. Remarkably, a feature of this model is that it explains muon g-2. More data is likely to confirm this elaborate edifice.

Title: Interpretations of the 750 GeV Excess in Extensions of E6
Comments: v3: added refs
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

In this paper, we address the recent diphoton resonance at run 2. Despite the fact that the diphoton peak could be a statistical fluctuation, we scrutinize the phenomenology of left-right models and analyze deviations to Higgs couplings. In short, a corollary of this model is that it explains the doublet-triplet splitting problem. Heavy scalars at 600 GeV should be observed soon. Finally, the diphoton anomaly is studied in composite twin Higgs with heavy scalars.

Title: The Diphoton Peak From Left-right Models

A few months ago, ATLAS and CMS have measured a resonance in run 2 of the LHC. New strong dynamics are added to technicolor to compensate for the diphoton peak. Consequently, the resonance is produced in photon fusion and decays to a pair of photons. Colored pions at 500 GeV should be observed soon. More data should reveal the nature of the diphoton excess.

Title: The $\gamma\gamma$ Resonance: Interpreting the $\gamma\gamma$ Peak in the Broken MRSSM

ATLAS and CMS have just shown a resonance in the second run of the LHC. The phenomenology of large N QCD is analyzed and we analyze the statistical significance. The $S$ couples not only to $ZZ$, but also to $Z\gamma$. Fortunately, the global U(1) symmetry protects the mass of the $X(750)$. Our results are similar to work done by Harigaya and Shang.
