Title: A New Take on Minimal Composite Higgs Inspired by the Diphoton Excess

Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

In this article, we talk about the very recent diphoton anomaly at run 2 and $B \to D \tau \nu$. We analyze the $\gamma\gamma$ anomaly in fat Higgs with new strong dynamics. A corollary of this model is that it cannot account for $B \to D \tau \nu$. Surprisingly, assuming the diphoton resonance is real, we predict that conformal dynamics should be at 700 GeV. More data is likely to confirm this profound theorem.

Less than a year ago, ATLAS and CMS have observed a peak in run 2. Actually, we analyze the 750 GeV anomaly in the NMSSM with neutralinos. Therefore, the $X(750)$ is produced in inelastic scattering and decays to a pair of photons. We expect an axion above 700 GeV. More data should reveal the nature of the diphoton peak.

In this letter, we look at the recent diphoton excess at run 2 (at 1.8 sigma). Moreover, we scrutinize the $\gamma\gamma$ resonance in folded SUSY. The shift symmetry protects the mass of the $S(750)$, but not the Higgs. Unsurprisingly, light axions at 400 GeV should be observed soon. Our results are similar to work done by Han.

Title: The 750 GeV Anomaly From $\lambda$SUSY

In this paper, we address the recent diphoton excess at run 2 and the diboson resonance. Curiously, the phenomenology of fat Higgs is scrutinized and we analyze the statistical significance. Surprisingly, the global U(1) symmetry stabilizes the mass of the resonance. Assuming the diphoton excess is real, we predict that vector-like quarks should be at 900 GeV. Finally, charge 1/3 quarks are added to split SUSY models to allow for the 750 GeV anomaly.

Title: A New Look at E6 Inspired by the $\gamma\gamma$ Excess
Comments: v4: 29 pages

ATLAS and CMS have just measured an anomaly in the second run of the LHC. Remarkably, we analyze the phenomenology of SU(3)^3 and derive branching ratios. The PQ symmetry stabilizes the mass of the resonance. Consequently, assuming the $\gamma\gamma$ excess is real, we predict that vector-like quarks should be at 800 GeV. We believe this is indicative of an elaborate fact.
