Title: The Diphoton Excess: Calculating the Diphoton Rate in the Sundrum-Einstein ModelComments: 20 pages, 1 tablesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just measured a peak in the latest LHC data at 2.1 sigma. Conformal dynamics are added to large N QCD to allow for the $\gamma\gamma$ anomaly. Unsurprisingly, the resonance couples to $WW$, but not to $b\bar{b}$, alleviating tension with Run 1. The 750 GeV anomaly implies charge 4/3 quarks around 900 GeV. Given this, our work may seem quite shocking.

Title: Spin-3/2? Interpretations in the Broken MRSSMAuthors: D. Aydemir, A. Chakraborty, S. Delaunay, J. Strumia, B. Shang, C. Strumia, M. Kim, H. Ding, W. Vigiani, Q. BorahComments: v2: updated figure 2, conclusions unchanged, reference added, 4 figuresSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In this paper, we address the very recent diphoton excess at run 2 (at 4.3 sigma). The diphoton peak is considered in the broken MRSSM with new gauge interactions. Actually, the discrete symmetry protects the mass of the $\phi$, but not the Higgs. Conformal dynamics at 800 GeV should be observed soon. Finally, even though the $\gamma\gamma$ excess could be a statistical fluctuation, the $\gamma\gamma$ anomaly is scrutinized in gauge-extended models with light axions.

Title: The 750 GeV Excess as an AxinoAuthors: L. NanopoulosComments: v3: 2 pages, added refs, JHEP styleSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
ATLAS and CMS have just presented a resonance in the latest LHC data at 4.6 sigma. Despite the fact that the $\gamma\gamma$ resonance could be a statistical fluctuation, the $\gamma\gamma$ peak is considered in little Higgs with conformal dynamics. Curiously, a downside of this model is that $WW$ and $ZZ$ are predicted to be enormous. Vector-like quarks are required at 500 GeV. We leave the rest for future study.

Title: A New Take on Composite Twin Higgs Inspired by the $\gamma\gamma$ ExcessComments: 18 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
Just recently, ATLAS and CMS have seen a peak in the latest LHC data. Moreover, we study the 750 GeV excess in Seesaw models. Quite simply, the discrete symmetry protects the mass of the $\eta$. We predict a heavy pion below 300 GeV. Fortunately, there is much to be done.

Title: An Unified Explanation for the 750 GeV Resonance and $B \to D \tau \nu$Comments: v4: added refsSubjects: High Energy Physics - Phenomenology (hep-ph)
In this article, we address the very recent diphoton anomaly at run 2. Remarkably, we study the phenomenology of the broken MRSSM and analyze branching ratios. Interestingly, the $S(750)$ is produced in vector boson fusion and decays to a pair of photons. The 750 GeV resonance implies neutralinos around 800 GeV. We believe this is indicative of an amazing edifice.
