Title: A New Take on Twin Higgs Inspired by the 750 GeV ExcessComments: v2: 21 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
Recently, ATLAS and CMS have shown a peak in run 2. We study the diphoton resonance in left-right models on 3-brane. The $\phi$ is produced in photon fusion and decays to $\gamma\gamma$. Moreover, we expect a color sextet above 800 GeV. Our results are similar to work done by Zhang.

Title: The $\gamma\gamma$ Anomaly: Interpreting the 750 GeV Resonance in Large N QCDComments: 18 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In this paper, we discuss the very recent diphoton peak at run 2 and the strong CP problem. We analyze the $\gamma\gamma$ peak in left-right models. The $S(750)$ couples not only to $Z\gamma$, but also to $t\bar{t}$. Surprisingly, the $\gamma\gamma$ resonance implies vector-like quarks around 500 GeV. More data is likely to confirm this charming framework.

Title: A New Take on Composite Models Inspired by the Diphoton AnomalyComments: 32 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
Less than a year ago, ATLAS and CMS have presented an excess in the 13 TeV data. The 750 GeV resonance is scrutinized in the Weinberg-Glashow model with charge 1/3 quarks. Remarkably, the discrete symmetry protects the mass of the $X$, but not the Higgs. Heavy scalars at 600 GeV should be observed soon. We leave the rest for future study.

Title: The 750 GeV Anomaly From 2HDMsComments: v4: 27 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this paper, we look at the very recent diphoton resonance at run 2 (at 3.0 sigma). In short, we consider the 750 GeV peak in little Higgs. The discrete symmetry protects the mass of the $\phi$. Moreover, we expect a color sextet above 700 GeV. Our results are similar to work done by Strumia.

Title: A New Take on the Sundrum-Polchinski Model Inspired by the $\gamma\gamma$ ExcessComments: 11 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this paper, we look at the very recent diphoton resonance at run 2. Actually, new strong dynamics are added to E6 to compensate for the 750 GeV peak. Interestingly, the R symmetry stabilizes the mass of the $X$. The 750 GeV resonance implies charge 5/3 quarks around 600 GeV. We will provide more details in a future paper.
