Title: The 750 GeV Resonance as an Eta
Comments: v4: 2 pages, added refs
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this article, we talk about the very recent diphoton excess at run 2 and the galactic center excess. We scrutinize the 750 GeV peak in flipped SU(5) models. A drawback of this model is that it encapsulates all the relevant physics. Unsurprisingly, colored pions are required at 800 GeV. We will provide more details in a future paper.

Title: A New Look at AdS/CFT Inspired by the $\gamma\gamma$ Excess
Comments: 12 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

Less than a year ago, ATLAS and CMS have reported a resonance in the latest LHC data. Remarkably, we scrutinize the $\gamma\gamma$ excess in minisplit SUSY models. The conformal symmetry stabilizes the mass of the $\phi$. Actually, we expect a sgoldstino above 800 GeV. Our results are similar to work done by Song and Su.

Title: Interpretations of the 750 GeV Anomaly in Extensions of E6
Authors: P. Li
Comments: 4 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this letter, we talk about the intriguing diphoton excess at run 2 (at 3.5 sigma). We analyze the 750 GeV anomaly in twin Higgs with neutralinos. The $X$ couples to $ZZ$, but not to $t\bar{t}$, alleviating tension with Run 1. Unfortunately, a drawback of this model is that $WW$ and $hh$ are predicted to be enormous. Our results are similar to work done by Harigaya and Arun.

Title: The 750 GeV Peak: Interpreting the 750 GeV Anomaly in SO(10)
Comments: v3: updated figure 4, conclusions unchanged
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

Just recently, ATLAS and CMS have seen an anomaly in the second run of the LHC. Thus, we scrutinize the phenomenology of large N QCD and compute flavor observables. Interestingly, the $X(750)$ is produced in elastic scattering and decays to the diphoton channel. The diphoton resonance implies light axions around 600 GeV. We will provide more details in a future paper.

Title: A New Look at Gauge-extended Models Inspired by the $\gamma\gamma$ Excess
Comments: 38 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

In this note, we look at the very recent diphoton anomaly at run 2 (at 4.1 sigma). We consider the phenomenology of Seesaw models and analyze flavor observables. Curiously, the flavor symmetry protects the mass of the $\eta$. New gauge interactions are required at 800 GeV. Given this, our work may seem quite ingenious.
