In this note, we discuss the intriguing diphoton peak at run 2 (at 3.3 sigma). New gauge interactions are added to two Higgs doublet models to account for the 750 GeV excess. Thus, the $\phi$ is produced in vector boson fusion and decays to the diphoton channel. Neutralinos are required at 700 GeV. More data should reveal the nature of the diphoton excess.

Title: Interpretations of the Diphoton Resonance in Extensions of Seesaw Models
Comments: v3: added refs, BibTeX
Subjects: High Energy Physics - Phenomenology (hep-ph)

Less than a year ago, ATLAS and CMS have seen a peak in the second run of the LHC. However, we study the diphoton resonance in $\lambda$SUSY on a lattice. The conformal symmetry stabilizes the mass of the $S$. Unsurprisingly, vector-like fermions are required at 900 GeV. We leave the rest for future study.

Title: A New Look at Fat Higgs Inspired by the $\gamma\gamma$ Excess
Comments: v2: 38 pages, added refs
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this paper, we discuss the recent diphoton peak at run 2 (at 1.1 sigma). Interestingly, even though the 750 GeV excess could be a statistical fluctuation, we scrutinize the 750 GeV excess in AdS/CFT on a torus. Unfortunately, the $X(750)$ couples to $t\bar{t}$, but not to $Z\gamma$, alleviating tension with Run 1. Assuming the 750 GeV peak is real, we predict that exotic fermions should be at 900 GeV. We leave the rest for future study.

Title: Relating the $\gamma\gamma$ Excess and the Diboson Resonance
Authors: J. Ren, H. Bi
Comments: 2 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

Less than a year ago, ATLAS and CMS have measured an excess in the latest LHC data. We analyze the phenomenology of AdS/CFT and compute the full mass spectrum. The conformal symmetry stabilizes the mass of the $S$. Surprisingly, a downside of this model is that it is very predictive. Remarkably, there is much to be done.

Title: A Common Framework for the 750 GeV Anomaly and the 2 TeV Resonance
Comments: 47 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this article, we discuss the very recent diphoton peak at run 2 and $B \to D \tau \nu$. Fortunately, the 750 GeV anomaly is analyzed in minimal composite Higgs with vector-like quarks. Quite simply, the resonance couples not only to $Z\gamma$, but also to $WW$. Assuming the diphoton anomaly is real, we predict that colored pions should be at 800 GeV. Our results are similar to work done by Hamada and Chiang.
