Title: A New Look at Folded SUSY Inspired by the $\gamma\gamma$ Peak
Authors: N. Park, X. Fichet
Comments: 4 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

ATLAS and CMS have just presented a resonance in the second run of the LHC at 1.4 sigma. New strong dynamics are added to two Higgs doublet models to explain the 750 GeV peak. The $\phi$ couples to $Z\gamma$, but not to $WW$, decreasing tension with Run 1. Interestingly, a corollary of this model is that it cannot account for muon g-2. Given this, our work may seem quite unforseen.

Title: A Common Framework for the 750 GeV Excess and $B \to D \tau \nu$
Authors: E. Cline, B. Zhang
Comments: v4: 4 pages, added refs
Subjects: High Energy Physics - Phenomenology (hep-ph)

ATLAS and CMS have just shown a resonance in the second run of the LHC. Unfortunately, we scrutinize the phenomenology of $\lambda$SUSY and derive decay widths. The $X(750)$ couples not only to $ZZ$, but also to $WW$. New gauge interactions are required at 300 GeV. More data should reveal the nature of the 750 GeV resonance.

Title: A New Look at Seesaw Models Inspired by the Diphoton Excess
Comments: v3: 46 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

In this article, we look at the very recent diphoton anomaly at run 2. Quite simply, while the $\gamma\gamma$ anomaly could be a statistical fluctuation, we scrutinize the phenomenology of split SUSY models and predict the statistical significance. Surprisingly, the resonance is produced in vector boson fusion and decays to two photons. We predict scalar singlet below 500 GeV. More data should reveal the nature of the diphoton anomaly.

Title: Relating the $\gamma\gamma$ Anomaly and the Strong CP Problem

Less than a year ago, ATLAS and CMS have shown an anomaly in the latest LHC data. Thus, we scrutinize the 750 GeV resonance in little Higgs. The $\phi$ is produced in vector boson fusion and decays to two photons. We predict an eta below 900 GeV. We leave the rest for future study.

Title: A New Take on Pati-Salam Models Inspired by the Diphoton Peak

In this letter, we talk about the intriguing diphoton excess at run 2 (at 4.3 sigma). The diphoton resonance is analyzed in minisplit SUSY models with vector-like quarks. A corollary of this model is that $Z\gamma$ and $WW$ are predicted to be sizable. Unfortunately, the $X$ is produced in elastic scattering and decays to two photons. Therefore, there is much to be done.
