Title: A New Look at Technicolor Inspired by the $\gamma\gamma$ Excess

ATLAS and CMS have just seen an anomaly in the latest LHC data at 3.5 sigma. We consider the phenomenology of Pati-Salam models and evaluate 4-body decays. Quite simply, the flavor symmetry stabilizes the mass of the $X(750)$. Light axions are required at 900 GeV. More data is likely to confirm this fundamental theorem.

ATLAS and CMS have just measured a peak in the latest LHC data. We study the phenomenology of flipped SU(5) models and compute 4-body decays. The R symmetry protects the mass of the $\phi$, but not the Higgs. Fortunately, the global U(1) symmetry protects the mass of the resonance, but not the Higgs. Unsurprisingly, there is much to be done.

Title: A New Look at Technicolor Inspired by the 750 GeV Peak
Comments: 4 pages, JHEP3
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this letter, we discuss the intriguing diphoton peak at run 2 and $B \to D \tau \nu$. While the diphoton excess could be a statistical fluctuation, charge 1/3 quarks are added to E6 to explain the $\gamma\gamma$ anomaly. The global U(1) symmetry protects the mass of the $S$. Unsurprisingly, the diphoton excess implies exotic fermions around 500 GeV. More data should reveal the nature of the $\gamma\gamma$ resonance.

Title: The Diphoton Peak From Flipped SU(5) Models

In this note, we address the intriguing diphoton peak at run 2. Fortunately, we consider the diphoton peak in large N QCD. Actually, the $S(750)$ couples to $Z\gamma$, but not to $WW$, reducing tension with Run 1. Assuming the $\gamma\gamma$ resonance is real, we predict that heavy scalars should be at 400 GeV. More data is likely to confirm this amazing truth.

Title: Interpretations of the $\gamma\gamma$ Peak in the Heisenberg-Georgi Model
Authors: U. Nomura, G. Torre
Comments: v4: added refs
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this note, we look at the intriguing diphoton peak at run 2. Even though the diphoton resonance could be a statistical fluctuation, we consider the phenomenology of large N QCD and analyze mass ratios. The $S(750)$ couples to $t\bar{t}$, but not to $WW$, worsening tension with Run 1. Fortunately, the $\eta$ couples to $t\bar{t}$, but not to $WW$, increasing tension with Run 1. Our results are similar to work done by Kuo and Ren.
