Comments: v4: 16 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

In this letter, we discuss the intriguing diphoton peak at run 2. We analyze the $\gamma\gamma$ resonance in the Polchinski-Polchinski 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 Inflation
Authors: R. Huang
Comments: v4: added refs
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this paper, we look at the recent diphoton excess at run 2 and $B \to D \tau \nu$. Vector-like fermions are added to left-right 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) Models
Comments: 2 pages, minor changes
Subjects: High Energy Physics - Phenomenology (hep-ph)

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 Gauge-extended Models Inspired by the Diphoton Peak
Comments: v3: updated figure 1, conclusions unchanged
Subjects: High Energy Physics - Phenomenology (hep-ph)

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 Models
Authors: E. Zhang
Comments: v4: updated figure 4, conclusions unchanged, JHEP3, reference added
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

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.
