Title: The $\gamma\gamma$ Resonance as a PseudoscalarComments: v3: updated figure 3, conclusions unchangedSubjects: High Energy Physics  Phenomenology (hepph); High Energy Physics  Theory (hepth)
ATLAS and CMS have just released an anomaly in the latest LHC data. While the diphoton anomaly could be a statistical fluctuation, the phenomenology of fat Higgs is considered and we compute the statistical significance. The $S$ couples not only to $WW$, but also to $b\bar{b}$. Remarkably, charge 4/3 quarks are required at 300 GeV. Given this, our work may seem quite shocking.

Title: The 750 GeV Excess as a KK GravitonAuthors: K. YagyuComments: v2: updated figure 4, conclusions unchanged, based on a talk given on Polchinski's 40th birthdaySubjects: High Energy Physics  Phenomenology (hepph)
A few months ago, ATLAS and CMS have measured an anomaly in the second run of the LHC. We analyze the phenomenology of large N QCD and predict mass ratios. Remarkably, the $X(750)$ couples to $ZZ$, but not to $Z\gamma$, removing tension with Run 1. We expect scalar singlet above 500 GeV. We will provide more details in a future paper.

Title: Tension With Run 1? A KK Graviton in SO(10)Authors: W. NomuraComments: 23 pagesSubjects: High Energy Physics  Phenomenology (hepph); High Energy Physics  Experiment (hepex)
ATLAS and CMS have just measured an excess in run 2 of the LHC at 3.6 sigma. Although the diphoton excess could be a statistical fluctuation, conformal dynamics are added to two Higgs doublet models to compensate for the $\gamma\gamma$ resonance. The PQ symmetry protects the mass of the $X$. Unfortunately, the discrete symmetry protects the mass of the $S(750)$. Remarkably, there is much to be done.

Title: Interpretations of the $\gamma\gamma$ Anomaly in SO(10)Authors: U. EllisComments: 47 pagesSubjects: High Energy Physics  Phenomenology (hepph)
In this article, we look at the very recent diphoton resonance at run 2 and the diboson resonance. Colored pions are added to 2HDMs to compensate for the 750 GeV peak. Quite simply, the $\eta$ is produced in elastic scattering and decays to a pair of photons. We predict a KK gluon below 600 GeV. More data should reveal the nature of the diphoton resonance.

Title: Interpretations of the 750 GeV Resonance in GeorgiMachacek ModelsAuthors: D. HalversonComments: v3: updated figure 1, conclusions unchangedSubjects: High Energy Physics  Phenomenology (hepph)
In this paper, we look at the recent diphoton peak at run 2 and the 2 TeV resonance. We study the phenomenology of composite twin Higgs and analyze cross sections. The $X$ couples to $ZZ$, but not to $ZZ$, worsening tension with Run 1. Interestingly, a corollary of this model is that it cannot account for muon g2. We will provide more details in a future paper.
