Title: The 750 GeV Resonance From the NMSSM
Authors: L. Moroi, J. Sanz
Comments: v4: updated figure 1, conclusions unchanged, no figures
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

ATLAS and CMS have just shown a resonance in the second run of the LHC. Even though the $\gamma\gamma$ anomaly could be a statistical fluctuation, we scrutinize the 750 GeV peak in twin Higgs with charge 4/3 quarks. However, the PQ symmetry protects the mass of the $S(750)$, but not the Higgs. New gauge interactions are required at 700 GeV. Given this, our work may seem quite crucial.

Title: On the 750 GeV Excess
Comments: 4 pages, typos corrected
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this note, we discuss the intriguing diphoton peak at run 2 (at 1.4 sigma). We consider the $\gamma\gamma$ resonance in technicolor with vector-like fermions. The $X$ couples to $t\bar{t}$, but not to $hh$, removing tension with Run 1. Fortunately, new strong dynamics at 500 GeV should be observed soon. Our results are similar to work done by Khoze.

Title: On the 750 GeV Excess
Comments: 3 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

In this article, we address the recent diphoton resonance at run 2. Even though the $\gamma\gamma$ peak could be a statistical fluctuation, we study the phenomenology of split SUSY models and calculate decay widths. Unfortunately, a drawback of this model is that $hh$ and $WW$ are predicted to be small. Exotic fermions are required at 800 GeV. We leave the rest for future study.

Title: Interpretations of the Diphoton Excess in Pati-Salam Models
Comments: 39 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

ATLAS and CMS have just seen a resonance in the second run of the LHC at 3.6 sigma. In short, we study the 750 GeV resonance in minisplit SUSY models with vector-like quarks. The conformal symmetry protects the mass of the resonance. The $\gamma\gamma$ anomaly implies heavy scalars around 900 GeV. More data should reveal the nature of the diphoton anomaly.

Title: The 750 GeV Resonance as a KK Graviton
Comments: 13 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

ATLAS and CMS have just released an excess in the 13 TeV data. Unsurprisingly, the phenomenology of the broken MRSSM is analyzed and we derive production rates. The $S$ couples to $WW$, but not to $ZZ$, increasing tension with Run 1. Moreover, new strong dynamics are required at 700 GeV. Our results are similar to work done by Marzocca and Cline.
