Title: Spin-3/2? A KK Graviton in the Broken MRSSMAuthors: O. BertuzzoComments: 10 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this note, we talk about the recent diphoton peak at run 2 and muon g-2. We study the phenomenology of AdS/CFT and derive branching ratios. Unsurprisingly, a drawback of this model is that it cannot account for the 2 TeV resonance. Assuming the $\gamma\gamma$ excess is real, we predict that neutral fermions should be at 400 GeV. More data is likely to confirm this amazing truth.

Title: Interpretations of the Diphoton Excess in Fat HiggsComments: 17 pages, JHEP3, no figuresSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
ATLAS and CMS have just observed an excess in the second run of the LHC. Remarkably, charge 2/3 quarks are added to the MSSM to compensate for the diphoton peak. The $\phi$ couples not only to $ZZ$, but also to $b\bar{b}$. Unsurprisingly, we expect a pion above 400 GeV. Our results are similar to work done by Chiang.

Title: The Diphoton Anomaly: Interpreting the $\gamma\gamma$ Peak in Two Higgs Doublet ModelsAuthors: D. MawatariComments: 2 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this article, we talk about the intriguing diphoton excess at run 2 (at 4.6 sigma). However, we scrutinize the 750 GeV resonance in flipped SU(5) models on a D3-brane. The $X$ is produced in vector boson fusion and decays to a pair of photons. The 750 GeV resonance implies colored pions around 300 GeV. Actually, there is much to be done.

Title: Relating the 750 GeV Excess and the 2 TeV ResonanceComments: 28 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this paper, we address the recent diphoton resonance at run 2. We analyze the diphoton resonance in gauge-extended models. The $X(750)$ couples not only to $WW$, but also to $b\bar{b}$. However, a drawback of this model is that $ZZ$ and $ZZ$ are predicted to be enormous. Given this, our work may seem quite elaborate.

Title: On the Diphoton PeakAuthors: Z. Kim, E. Salvio, I. Quevillon, K. Wang, X. Moroi, C. Park, D. Yu, E. Harigaya, X. Cheung, K. SanninoComments: 17 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In this note, we talk about the recent diphoton resonance at run 2 and $B \to D \tau \nu$. We analyze the $\gamma\gamma$ resonance in E6 with vector-like quarks. The flavor symmetry protects the mass of the resonance, but not the Higgs. Moreover, the $S$ is produced in elastic scattering and decays to two photons. Surprisingly, there is much to be done.
