In this article, we discuss the very recent diphoton excess at run 2 and muon g-2. We study the diphoton anomaly in singlet-extended models on 3-brane. A corollary of this model is that it is very predictive. Therefore, the discrete symmetry stabilizes the mass of the $\phi$. More data should reveal the nature of the diphoton resonance.

Title: How Wide? Interpretations in Split SUSY Models
Comments: v2: 18 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

ATLAS and CMS have just observed a resonance in the 13 TeV data. We scrutinize the $\gamma\gamma$ excess in composite twin Higgs. Interestingly, the discrete symmetry protects the mass of the $\phi$. We expect a pion above 700 GeV. Given this, our work may seem quite shocking.

ATLAS and CMS have just observed an anomaly in the second run of the LHC at 4.6 sigma. Unfortunately, the diphoton resonance is studied in E6 with heavy scalars. Unsurprisingly, a downside of this model is that $b\bar{b}$ and $ZZ$ are predicted to be small. Exotic fermions are required at 400 GeV. We believe this is indicative of an elaborate pattern.

Title: A New Look at Composite Twin Higgs Inspired by the 750 GeV Resonance
Comments: 41 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this paper, we discuss the intriguing diphoton resonance at run 2. We analyze the phenomenology of singlet-extended models and evaluate decay widths. However, the discrete symmetry protects the mass of the $S(750)$. We predict a color sextet below 600 GeV. Remarkably, there is much to be done.

Title: Interpretations of the 750 GeV Anomaly in Extensions of $\lambda$SUSY

In this note, we discuss the recent diphoton resonance at run 2. In short, while the $\gamma\gamma$ anomaly could be a statistical fluctuation, the phenomenology of two Higgs doublet models is studied and we analyze the statistical significance. Curiously, the R symmetry stabilizes the mass of the $\phi$. Vector-like quarks at 600 GeV should be observed soon. We leave the rest for future study.
