Title: A New Look at Large N QCD Inspired by the Diphoton Resonance
Comments: 27 pages, reference added, Latex file
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this article, we discuss the recent diphoton excess at run 2. Although the 750 GeV excess could be a statistical fluctuation, we scrutinize the diphoton anomaly in Pati-Salam models with neutralinos. The $X$ couples to $t\bar{t}$, but not to $b\bar{b}$, reducing tension with Run 1. Unsurprisingly, we expect a pseudoscalar above 400 GeV. More data is likely to confirm this elegant pattern.

Title: A New Look at Split SUSY Models Inspired by the $\gamma\gamma$ Peak
Authors: Q. Strumia
Comments: v2: updated figure 1, conclusions unchanged
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this note, we address the recent diphoton resonance at run 2 (at 2.0 sigma). Moreover, despite the fact that the 750 GeV anomaly could be a statistical fluctuation, we consider the 750 GeV peak in left-right models. Consequently, the $\phi$ is produced in the quark antiquark channel and decays to a pair of photons. The 750 GeV anomaly implies vector-like fermions around 300 GeV. However, there is much to be done.

Title: A New Take on Seesaw Models Inspired by the $\gamma\gamma$ Peak
Authors: S. Yu
Comments: 35 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this paper, we address the very recent diphoton peak at run 2 (at 3.3 sigma). The 750 GeV peak is studied in two Higgs doublet models with vector-like quarks. The $\phi$ couples not only to $b\bar{b}$, but also to $Z\gamma$. However, the 750 GeV anomaly implies heavy scalars around 500 GeV. Given this, our work may seem quite remarkable.

Title: The $\gamma\gamma$ Peak: Interpretations in Little Higgs
Comments: 4 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this article, we discuss the intriguing diphoton anomaly at run 2. Surprisingly, we scrutinize the $\gamma\gamma$ anomaly in Georgi-Machacek models on AdS_5. The $\eta$ couples to $t\bar{t}$, but not to $ZZ$, worsening tension with Run 1. Assuming the diphoton anomaly is real, we predict that new gauge interactions should be at 400 GeV. Our results are similar to work done by Orikasa and Wang.

Title: A New Take on Technicolor Inspired by the Diphoton Peak
Authors: N. Ghosh, Y. Hubisz
Comments: 37 pages, 2 tables
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this article, we discuss the very recent diphoton excess at run 2 and the core-cusp problem. We scrutinize the $\gamma\gamma$ excess in SU(3)^3 on a torus. A feature of this model is that it is very predictive. In short, we expect a pseudoscalar above 400 GeV. Our results are similar to work done by Sanz.
