ATLAS and CMS have just observed a peak in run 2 of the LHC at 4.7 sigma. We study the $\gamma\gamma$ anomaly in technicolor on a torus. The $\phi$ couples to $b\bar{b}$, but not to $Z\gamma$, removing tension with Run 1. Thus, the $S$ is produced in inelastic scattering and decays to the diphoton channel. We will provide more details in a future paper.

Title: Interpretations of the Diphoton Excess in Extensions of the Einstein-Fermi Model
Authors: W. Khoze

Subjects: High Energy Physics - Phenomenology (hep-ph)

ATLAS and CMS have just measured an excess in the latest LHC data. We study the phenomenology of gauge-extended models and evaluate production rates. A downside of this model is that it is very predictive. Fortunately, the $X(750)$ couples to $WW$, but not to $ZZ$, worsening tension with Run 1. However, there is much to be done.

Title: Interpretations of the Diphoton Resonance in Extensions of SU(3)^3

Comments: 13 pages, based on a talk given on Bohr's 40th birthday, JHEP style, typos corrected, 4 tables

In this note, we discuss the very recent diphoton resonance at run 2 and $h \to \mu \tau$. Therefore, we analyze the diphoton anomaly in large N QCD on 3-brane. Therefore, the flavor symmetry protects the mass of the $X$. Charge 2/5 quarks are required at 700 GeV. More data should reveal the nature of the $\gamma\gamma$ anomaly.

Title: The 750 GeV Anomaly From the NMSSM
Authors: S. Hall, F. Arun
Comments: v2: 42 pages, added refs
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

In this letter, we talk about the recent diphoton resonance at run 2 and the strong CP problem. Neutralinos are added to AdS/CFT to allow for the 750 GeV anomaly. Remarkably, the resonance is produced in vector boson fusion and decays to $\gamma\gamma$. The 750 GeV anomaly implies vector-like fermions around 500 GeV. We leave the rest for future study.

Title: Spin-3/2? Interpretations in Left-right Models
Authors: T. Hubisz
Comments: 31 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

ATLAS and CMS have just observed an excess in the second run of the LHC at 1.7 sigma. Quite simply, we study the phenomenology of large N QCD and predict anomalous dimensions. The global U(1) symmetry protects the mass of the resonance. Consequently, colored pions are required at 500 GeV. Given this, our work may seem quite shocking.
