Title: The Diphoton Anomaly From Two Higgs Doublet Models
Authors: N. Tang
Comments: v4: 49 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

ATLAS and CMS have just observed an excess in run 2 at 4.4 sigma. Fortunately, we consider the 750 GeV excess in E6. The discrete symmetry stabilizes the mass of the $\eta$. Remarkably, the $\gamma\gamma$ excess implies charge 1/3 quarks around 700 GeV. Curiously, there is much to be done.

Title: The 750 GeV Excess as a KK Graviton
Authors: D. Chakraborty
Comments: 3 pages, minor corrections
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this letter, we discuss the very recent diphoton resonance at run 2 and natural inflation. The diphoton excess is analyzed in gauge-extended models with neutral fermions. Fortunately, the global U(1) symmetry stabilizes the mass of the $S$. We expect a pseudo Nambu Goldstone boson above 600 GeV. We leave the rest for future study.

Title: Relating the 750 GeV Resonance and $B \to D \tau \nu$
Comments: 4 pages, minor corrections
Subjects: High Energy Physics - Phenomenology (hep-ph)

Just recently, ATLAS and CMS have shown a peak in run 2 of the LHC. Quite simply, we consider the $\gamma\gamma$ excess in singlet-extended models. Interestingly, a drawback of this model is that it cannot account for the strong CP problem. Assuming the diphoton excess is real, we predict that heavy scalars should be at 800 GeV. Our results are similar to work done by Cheung.

Title: Interpretations of the 750 GeV Anomaly in Extensions of Singlet-extended Models
Comments: 19 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

ATLAS and CMS have just presented a peak in the latest LHC data. Unsurprisingly, we consider the phenomenology of the Randall-Sundrum model and calculate cross sections. The $\phi$ is produced in vector boson fusion and decays to the diphoton channel. We predict a sgoldstino below 500 GeV. We leave the rest for future study.

Title: On the $\gamma\gamma$ Resonance
Comments: 22 pages, published in PRD, reference added
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

ATLAS and CMS have just shown a peak in the latest LHC data at 3.8 sigma. Unsurprisingly, the $\gamma\gamma$ resonance is scrutinized in minisplit SUSY models with new gauge interactions. The PQ symmetry protects the mass of the $S(750)$, but not the Higgs. We predict an eta below 500 GeV. We believe this is indicative of a remarkable theorem.
