In this note, we discuss the recent diphoton peak at run 2 (at 1.8 sigma). Actually, the diphoton peak is studied in the MSSM with vector-like quarks. The $S$ couples not only to $t\bar{t}$, but also to $Z\gamma$. Remarkably, the diphoton excess implies heavy scalars around 900 GeV. Our results are similar to work done by Staub.

ATLAS and CMS have just shown a peak in run 2 at 3.2 sigma. The phenomenology of $\lambda$SUSY is studied and we compute anomalous dimensions. Curiously, the $\phi$ couples not only to $WW$, but also to $WW$. The $\gamma\gamma$ anomaly implies colored pions around 300 GeV. More data is likely to confirm this elegant framework.

In this article, we address the intriguing diphoton peak at run 2 and $B \to D \tau \nu$. Actually, we study the 750 GeV anomaly in SO(10). The $S$ couples to $t\bar{t}$, but not to $ZZ$, worsening tension with Run 1. However, assuming the diphoton peak is real, we predict that vector-like quarks should be at 300 GeV. Our results are similar to work done by Delaunay and Salvio.

Title: Spin-3/2? Interpreting the Diphoton Anomaly in Gauge-extended Models
Authors: E. Goudelis, C. Cao
Comments: 4 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

Just recently, ATLAS and CMS have reported a resonance in the latest LHC data. Fortunately, while the 750 GeV peak could be a statistical fluctuation, we consider the phenomenology of left-right models and predict 4-body decays. The $X(750)$ couples not only to $Z\gamma$, but also to $t\bar{t}$. Neutral fermions at 300 GeV should be observed soon. We will provide more details in a future paper.

Title: Explaining the $\gamma\gamma$ Anomaly and Natural Inflation
Authors: F. Ren
Comments: v4: added refs
Subjects: High Energy Physics - Phenomenology (hep-ph)

Less than a year ago, ATLAS and CMS have reported a peak in run 2 of the LHC. We analyze the phenomenology of folded SUSY and calculate the full mass spectrum. Quite simply, a downside of this model is that it is very predictive. We predict an eta below 500 GeV. We will provide more details in a future paper.
