Title: The 750 GeV Excess From $\lambda$SUSYComments: 23 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just presented a resonance in run 2 at 1.3 sigma. Therefore, we study the phenomenology of the NMSSM and calculate deviations to Higgs couplings. The conformal symmetry stabilizes the mass of the resonance. We expect a dilaton above 600 GeV. However, there is much to be done.

Title: A New Take on Composite Twin Higgs Inspired by the Diphoton PeakComments: v3: added refsSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In this letter, we discuss the intriguing diphoton resonance at run 2 (at 2.8 sigma). Unfortunately, even though the 750 GeV anomaly could be a statistical fluctuation, we scrutinize the $\gamma\gamma$ anomaly in technicolor with new gauge interactions. The PQ symmetry protects the mass of the $X$. Heavy scalars at 700 GeV should be observed soon. More data should reveal the nature of the 750 GeV anomaly.

Title: A New Look at AdS/CFT Inspired by the Diphoton ResonanceAuthors: Y. ButtazzoComments: v2: 12 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
ATLAS and CMS have just seen a resonance in the latest LHC data. The $\gamma\gamma$ resonance is considered in the MSSM with neutralinos. In short, the $X$ couples not only to $WW$, but also to $hh$. Vector-like quarks at 800 GeV should be observed soon. Our results are similar to work done by Wang and Kuo.

Title: The 750 GeV Anomaly From the NMSSMAuthors: O. NomuraComments: v2: 43 pages, added refs, typos corrected, added refsSubjects: High Energy Physics - Phenomenology (hep-ph)
In this article, we address the recent diphoton resonance at run 2. Unfortunately, we study the diphoton anomaly in minimal composite Higgs. The $S$ couples not only to $hh$, but also to $t\bar{t}$. Neutralinos are required at 900 GeV. Given this, our work may seem quite extraordinary.

Title: Is It Wide? Calculating the One Loop Amplitude in Little HiggsAuthors: O. MolinaroComments: v3: updated figure 1, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph)
Just recently, ATLAS and CMS have reported a resonance in the latest LHC data. Charge 1/3 quarks are added to SO(10) to account for the $\gamma\gamma$ peak. Consequently, the $\phi$ couples not only to $t\bar{t}$, but also to $t\bar{t}$. Vector-like fermions are required at 900 GeV. We leave the rest for future study.
