Title: Interpretations of the Diphoton Anomaly in Little HiggsComments: v4: 16 pagesSubjects: High Energy Physics  Phenomenology (hepph); High Energy Physics  Experiment (hepex)
In this letter, we discuss the intriguing diphoton peak at run 2. We analyze the $\gamma\gamma$ resonance in the PolchinskiPolchinski model with light axions. Fortunately, the conformal symmetry stabilizes the mass of the $\eta$. The 750 GeV anomaly implies conformal dynamics around 300 GeV. We leave the rest for future study.

Title: Explaining the $\gamma\gamma$ Resonance and Natural InflationAuthors: R. HuangComments: v4: added refsSubjects: High Energy Physics  Phenomenology (hepph)
In this paper, we look at the recent diphoton excess at run 2 and $B \to D \tau \nu$. Vectorlike fermions are added to leftright models to compensate for the 750 GeV peak. Quite simply, the R symmetry stabilizes the mass of the $\phi$. Exotic fermions at 600 GeV should be observed soon. More data should reveal the nature of the 750 GeV peak.

Title: Interpretations of the 750 GeV Anomaly in Flipped SU(5) ModelsComments: 2 pages, minor changesSubjects: High Energy Physics  Phenomenology (hepph)
Just recently, ATLAS and CMS have measured a peak in the second run of the LHC. We study the diphoton peak in two Higgs doublet models on warped metric. A corollary of this model is that it cannot account for natural inflation. Curiously, we predict a pseudoscalar below 400 GeV. Interestingly, there is much to be done.

Title: A New Take on Gaugeextended Models Inspired by the Diphoton PeakAuthors: J. Yu, H. Ding, M. Torre, U. Sanz, V. Sadhukhan, H. Zhang, B. Sannino, M. Mohapatra, H. Ren, S. SenguptaComments: v3: updated figure 1, conclusions unchangedSubjects: High Energy Physics  Phenomenology (hepph)
In this note, we address the very recent diphoton anomaly at run 2 (at 1.0 sigma). Therefore, the 750 GeV excess is scrutinized in minisplit SUSY models with neutralinos. Therefore, the resonance couples to $hh$, but not to $ZZ$, alleviating tension with Run 1. We expect an eta prime above 800 GeV. More data is likely to confirm this critical pattern.

Title: The Diphoton Peak From Composite ModelsAuthors: E. ZhangComments: v4: updated figure 4, conclusions unchanged, JHEP3, reference addedSubjects: High Energy Physics  Phenomenology (hepph); High Energy Physics  Experiment (hepex)
In this paper, we discuss the intriguing diphoton anomaly at run 2 and $h \to \mu \tau$. We scrutinize the diphoton excess in twin Higgs with charge 1/5 quarks. The discrete symmetry stabilizes the mass of the $X(750)$. Curiously, we expect a KK graviton above 800 GeV. However, there is much to be done.
