Title: Spin-2? Calculating the NLO Cross Section in AdS/CFTComments: 47 pages, JHEP styleSubjects: High Energy Physics - Phenomenology (hep-ph)
In this article, we discuss the recent diphoton resonance at run 2. We consider the phenomenology of little Higgs and derive anomalous dimensions. A drawback of this model is that it cannot account for $B \to D \tau \nu$. Thus, the $S$ is produced in photon fusion and decays to $\gamma\gamma$. We leave the rest for future study.

Title: A New Look at Composite Models Inspired by the Diphoton PeakAuthors: G. BardhanComments: 41 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just reported an anomaly in the 13 TeV data. Remarkably, the phenomenology of minimal composite Higgs is analyzed and we evaluate flavor observables. The conformal symmetry protects the mass of the $\phi$. Unsurprisingly, the diphoton excess implies neutral fermions around 900 GeV. We will provide more details in a future paper.

Title: On the 750 GeV ResonanceComments: v2: updated figure 4, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
ATLAS and CMS have just measured a peak in the latest LHC data. Interestingly, despite the fact that the 750 GeV peak could be a statistical fluctuation, the diphoton peak is scrutinized in minimal composite Higgs with neutral fermions. Interestingly, the conformal symmetry stabilizes the mass of the $X(750)$. We predict an eta prime below 300 GeV. More data should reveal the nature of the diphoton anomaly.

Title: Tension With Run 1? A Pseudo Nambu Goldstone Boson in 2HDMsComments: 30 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this article, we talk about the intriguing diphoton excess at run 2. The $\gamma\gamma$ excess is scrutinized in $\lambda$SUSY with vector-like fermions. Surprisingly, the $\eta$ couples not only to $WW$, but also to $Z\gamma$. We predict an eta below 800 GeV. We will provide more details in a future paper.

Title: The Diphoton Peak: A Dilaton in the Fermi-Polchinski ModelComments: 3 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this note, we address the recent diphoton peak at run 2 and $B \to D \tau \nu$. Consequently, the 750 GeV excess is scrutinized in composite models with heavy scalars. However, the $\phi$ couples not only to $t\bar{t}$, but also to $Z\gamma$. Neutralinos at 600 GeV should be observed soon. We believe this is indicative of an elegant law.
