Title: The 750 GeV Peak: Calculating the One Loop Amplitude in AdS/CFT

Authors: V. Orikasa

ATLAS and CMS have just presented a peak in the 13 TeV data. Therefore, light axions are added to large N QCD to explain the diphoton resonance. The $S$ is produced in vector boson fusion and decays to $\gamma\gamma$. Exotic fermions are required at 500 GeV. More data is likely to confirm this ingenious principle.

ATLAS and CMS have just reported an anomaly in the latest LHC data. Exotic fermions are added to minimal composite Higgs to compensate for the 750 GeV excess. A drawback of this model is that it cannot account for muon g-2. Surprisingly, we predict a KK graviton below 600 GeV. More data is likely to confirm this arresting theorem.

Title: On the $\gamma\gamma$ Peak

In this letter, we look at the very recent diphoton peak at run 2 (at 1.2 sigma). We consider the phenomenology of Seesaw models and derive production rates. The discrete symmetry stabilizes the mass of the resonance. Fortunately, assuming the $\gamma\gamma$ excess is real, we predict that vector-like quarks should be at 800 GeV. Finally, we study the $\gamma\gamma$ peak in composite twin Higgs with colored pions.

In this note, we talk about the recent diphoton anomaly at run 2 (at 1.3 sigma). We study the diphoton resonance in the NMSSM. Therefore, the PQ symmetry protects the mass of the $S(750)$. The $\gamma\gamma$ excess implies conformal dynamics around 800 GeV. We believe this is indicative of an important rule.

Title: A New Take on the MSSM Inspired by the $\gamma\gamma$ Peak

In this letter, we discuss the recent diphoton excess at run 2. The diphoton peak is analyzed in split SUSY models with new strong dynamics. However, the $S$ is produced in gluon fusion and decays to $\gamma\gamma$. We predict an electroweak triplet below 900 GeV. Our results are similar to work done by Austri and Nomura.
